Automatically updating to the release or test versions of Acorn

Auto-update to test releases (newest, super fun development releases)
Auto-update to regular releases (boring old production releases)

Acorn 7.1.2
?, 2021.

# Other

  • Export will remember the last location you saved your image to for subsequent exports (it'll first default to where the image was opened from though).
    Related to this - if you would rather Acorn not default to the opening location of the image, you can use the following hidden pref to disable that:
    defaults write com.flyingmeat.Acorn7 ignoreDocumentLocationOnExport

# Bug Fixes

  • Fixed a problem where Acorn couldn't directly save a TGA file it had opened and edited.
  • Fixed a problem where the line height of a text box could be reset when editing it.
Acorn 7.1.1
October 27th, 2021.

# New Stuff

  • Pro Motion support, which means 120fps updates for those of you lucky enough to have one of Apple's new M1 MacBook Pros. Sweet, sweet, buttery smooth graphics.
  • Support for MacOS 12 Monterey.
  • New "RGBA Multiplier" filter, which lets you multiply the various components of a pixel by a specified amount.
  • The export window now has an option for a layered TIFF file (also known as a multipage TIFF).
  • The "MozJPEG" option in the export window has been renamed to "JPEG (MozJPEG)" so that it's more obvious it's a regular JPEG, but using a different encoder.
  • Improved support for navigating the filter popup when using the keyboard.

# New Scripting Things

  • You can now use AppleScript to make a magic wand selection with the command "wand select location {2, 5} tolerance 5", where the location is the x,y coordinate of the start of the selection (with the origin to the bottom left of the image).
  • You can now specify the selection mode (new/add/subtract/intersect) when scripting an oval, rect, or magic wand selection. The default is "new" if none is specified.

# Changes

  • When you're editing a layer mask and press the delete key the mask (or selected area) will now fill with white, effectively removing the mask. Previously Acorn would fill with black which added to the mask. This change brings Acorn in line with the behavior of other major image editors (and obviously makes more sense to remove the mask when delete is pressed).
  • Acorn will remember and use the last image size created via the File ▸ New menu item when making a new image. However, if you have an image on the clipboard Acorn will still use those dimensions for the New Image window.

# Bug Fixes

  • Fixed a problem where the color profile information was not included when exporting an image as WebP.
  • Fixed a problem where images would open up scaled at 50% when on a 1x display if there was a second 2x display also attached.
Acorn 7.1
August 31st, 2021.

# New Stuff and Changes

  • The Export window now has a share toolbar item, so you can send your exported image direct to Mail or other apps (10.15+).
  • The Export window has a new "Copy to Clipboard" button in the lower left corner.
  • Added support for Mozilla's MozJPEG encoder in the Export window (and also available via AppleScript via the "web export" command).
  • Acorn is a lot faster at opening up animated GIF and PNG files with lots of frames. It also uses way less memory when doing so now on your M1 Macs.
  • The sheet for adding filters is now a popover. This is awesome if you're on MacOS 11 or later and you're tired of seeing your image being dimmed out when you bring it up.
  • When using the rotation dial in the shape inspector, it will always round to nice whole values. But if you want super precise values when using the dial, hold down the option key.
  • New fussy pref: "Use PDF import window with New from Clipboard". This is awesome if you have PDF data on the clipboard and you want to get a preview of the image or change the DPI of the rasterized PDF or even give it a background color.
  • The action menu in the filters and shape processors inspector will now let you enable and disable all filters. In addition, the controls for the filters will become disabled if you turn off their visibility.
  • Updated the fuzzy matching algorithm for the Command Bar so it gets slightly better results.
  • If you have Acorn's color picker up, Command-Shift-C will close it (or bring it back up if it's already gone. It acts as a toggle now!)
  • Double clicking on a color in Acorn's color picker will now dismiss the color picker.
  • Updated the iOS presets in the new image window.
  • The AppleScript paste command now returns a layer object when the clipboard contains something that'll make a new layer.

# Bug Fixes

  • Made some tweaks to how Acorn's color sampler works when picking images out from the screen, where previously things might get wonky with certain display setups.
  • Fixed a problem where Export option for a background matte wouldn't work for Animated GIFs.
  • Fixed a problem where a font name in the font popup for background windows might change on you when it didn't make sense to.
  • Fixed a problem where the "Lock dimensions" setting wasn't saved along with a crop preset.
  • Fixed a problem where selecting a gray color profile on export would remove the alpha channel from your image.
  • Fixed a problem where the "Fill expansion with color" option when resizing a canvas could add just a bit _too_ much color to your image.
  • Fixed a problem where painting might not show up correctly on certain layers after moving them around a bit.
  • Fixed a problem where copying a layer to a mask could remove the original layer if the original layer and mask were on the same row, resulting in a sad outcome.
  • Fixed some problems where changing the text color might not work.
  • Fixed some problems where the Touch Bar wouldn't show the right controls for the Pencil tool.
  • Cleaned up some shape layer handle drawing when resizing multiple selected shapes.
  • Fixed problem where duplicated layers would get a blank name.
  • Fixed problem where histograms weren't showing up on 10.15.7 after Apple's Security Update 2021-002 Catalina was installed.

# Other

  • Shape shadow offsets no longer clamp to 200/-200 pixels.
  • Cleanup of some tool icons.
  • The zoom to fit shortcut is now 8% more accurate.
  • Tweaked the way histograms are drawn a little for the Levels filter.
  • Previewing some RAW files should be faster now.
  • The slider for the Exposure setting in the Dodge and Burn brushes now looks and acts like the other sliders in that inspector.
Acorn 7.0.3
April 28, 2021.

# New Stuff and Changes

  • New option in export for PNG files: Crush / übercompress. This toggle, which has always been on by default, will allow you to turn off the advanced compression routines for PNG files. This is awesome if you just want a quick and dirty PNG and don't care about file size.
  • Updated shape handle cursors for @2x displays.
  • In the shape inspector, clicking on the stroke checkbox no longer sets a default stroke value to all the selected shapes. Now it just keeps whatever value was already there.
  • Updated Polish localization.
  • New hidden pref for controlling the resolution of PDF data on the clipboard: defaults write com.flyingmeat.Acorn7 newDocPDFClipboardResolution 600 - where 600 is the DPI you would like the PDF to be rasterized at.

# Bug Fixes

  • Fixed problem where dragging and dropping an Illustrator .ai file into Acorn's canvas would cause it to lock up.
  • Fixed an issue when toggling between floating inspectors where the current tool wouldn't always load.
  • Fixed a little UI glitch when using the keyboard while changing the quality of a JPEG in the export window.
  • Fixed a problem where the tool icons in the bezier menu in the tools inspector wouldn't match the current dark/normal appearance settings.
  • Fixed a problem where option-dragging a text shape to duplicate it wouldn't copy over the stroke settings.
  • Fixed a crasher when using the Smudge tool on M1 Macs.
  • Fixed a problem where the values from quality slider for HEIC files in the Save As… sheet wasn't being passed along to the encoder.
  • Fixed a problem where the Reset All Image Metadata button in the File Info window might not work.
  • Fixed a crasher under certain conditions when switching the appearance of Acorn.
Acorn 7.0.2
April 1st, 2021.

# Changes

  • Pinch to zoom with your trackpad now works in Export, RAW Import, and New View windows.
  • Double clicking on the image name in the toolbar will now zoom the window on MacOS 10.14 and 10.15.
  • When making new shapes, pressing the ESC while you've still got the mouse down will cancel the creation of that shape.
  • Acorn is better at importing SVG files that were created from Apple's SF Symbols app.
  • Exported animated GIFs will now loop forever.

# Bug Fixes

  • Fixed a problem where changes in the color picker for the value field wasn't updating the color.
  • Acorn does a better job at fitting the content size to the window when the Window ▸ Zoom Window menu item is used.
  • Fixed a problem where the wrong cursor could come up when modifying an anchor in a bezier path when it's first being created.
  • Fixed a problem where the cursor for the Bezier Freehand tool might not show up.
  • Fixed a problem where the y value of a drop shadow might be displaying incorrectly if you had the canvas origin set to top left.
  • Fixed a problem where you couldn't disable a matte background in the new export window.
  • Fixed a regression from Acorn 6 where you couldn't drag an existing bitmap layer into another layer's mask.
  • Fixed a problem where you couldn't save a crop preset.
  • Fixed a problem where exporting as WebP wouldn't keep the alpha channel.
  • German localization fixes.
  • Fixed an issue where the FPS for animated GIFs wouldn't be set correctly on some images.
Acorn 7.0.1
March 22, 2021.

# Bug Fixes

  • Fixed an issue where drawing with the pixel tool might cause the last pixel placement to disappear.
  • Fixed a problem where the Show Registration Certificate menu item wasn't showing up.
  • Fixed a crasher when using the Hue Shift shape processor under certain conditions.
  • Acorn will now throw up a warning if it can't make a layered screenshot because of system security preferences.
  • German localization fixes.
Acorn 7
March 17, 2021.
Acorn 7 is a universal binary for Apple Silicon Macs and requires MacOS 10.14 Mojave, 10.15 Catalina, or MacOS 11 Big Sur.

# New Stuff

  • An all new interface
    Acorn now sports a unified window with a matching toolbar. Gone are the floating palettes everywhere and getting in your way. Palettes are now inspectors and can be brushed away by pressing the TAB key, and brought back the same way. Acorn also adopts many new MacOS Big Sur conventions to make it look and feel like it belongs on a Mac. If you prefer the previous behavior where inspectors are in their own windows, there is a preference to enable that.

    Speaking of tabs, Acorn has a new preference for opening up images in tabs. So now you can gather all of your open images under a single window.

  • Über Export
    A new export workflow gives you options for specifying a color profile (like CMYK or Gray), more formats to save as (now including WebP!), precise file size of your export, and a live preview even for PDFs. This new workflow builds on and merges the previous Web Export window, but now with tons more options.
    The File ▸ Share menu items also work when the Export window is up. So if you're just interested in mailing an image off to a friend after resizing it a little in the export window, this is a great way to go.
  • Animated GIF export
    This is a new option is part of the new export workflow, and allows you to export all the layers in an image as an animated GIF. You can open up existing animated GIFs, change a single frame or apply filters to a range of frames. You can then export your GIF with the original frames per second or speed or slow it down.

  • New color picker
    We built a brand new color picker from the ground up which is super accurate, supports wide gamuts like Display P3, uses 64 bits for super accurate color values (and representing over 281 trillion colors), lets you adjust RGB and HSV values without switching modes, and handles your various color profiles perfectly.

  • Speed
    We've always got your eyes on ways to make Acorn even faster. This time around we managed to make Flood Fill, Instant Alpha, and Magic Wand multithreaded and up to 3x faster. Filters have also been fully optimized for Metal on Apple Silicon and Intel Macs. We've also made tweaks to the Metal pipeline which should make Acorn even more responsive than ever.

  • Universal Build
    We'll say it again in case you missed it, but Acorn is now full optimized for Apple Silicon Macs. It's fast.

  • New Command Bar
    Using the File ▸ Command Bar menu item (shortcut key ⌘⇧O) will bring up a little text window you can type in to find menu commands or other hidden commands. You can also search Acorn's help documentation with this.
    • Type "h" followed by a space and then a help topic to only search documentation. For instance, if you typed "h crop" it will return all documentation related to the crop tool.
    • There are some entries which do not show up in the menu bar, but which can be useful: Toggle Dark Aqua, Fill Layer, Fill Layer With Stroke Color, Feather (10px radius), Use Pixels for Ruler, Toggle Stroke/Fill, Change Canvas Background, Capitalize/Lowercase/Uppercase Text.

  • RAW import improvements
    You can now Save presets for your RAW images. We've also rebuilt the import preview allowing you to zoom in and out of your image, all powered by Metal of course.

  • New Navigation & Zoom Inspector
    Get an overview of your whole image, at any zoom level. Move the viewfinder in the inspector to change what you're looking at on your canvas. Use the histogram as an overview for the color balances in your image.

  • Perspective Fix & Crop tool
    This cool little tool will help you draw a grid on the canvas which you can use to help fix images where there are problematic perspective distortions.

  • New Fussy Preference: "Use short file extensions (jpg & tif)". Now, I know what you're thinking. You're thinking "Really? Really this was added as a preference? This is what time was spent on?" Well some of you are very, very vocal about this. And for years I've tried to appease you by pointing out that this is what MacOS does by default, but still… you were never happy. But now, well I hope this preference will make your day a little better and you can focus your energies on sending me emails about other things you wish were different in Acorn. I wonder what those will be?

# Good Things Got Better

  • Double clicking on a bitmap layer with the move tool will begin a scale and rotate transform for the layer. This also works with selections! If you have a selection on a bitmap layer you can switch to the move tool (or hold down the command key with a selection tool active) and double click within the selection to begin transforming it. You can press the esc key to exit the transform and undo any changes, or press the enter key to commit it.
  • You can now set a background fill color when resizing your canvas. If you have more than one layer, then Acorn will use the bottom bitmap layer in your image. If there is a layer on the bottom that is not a bitmap layer, then the fill options will not be enabled.
  • The brush palette now has the option to set spacing for brushes. Previously you could only do this in the Brush Designer window.
  • If you use the contextual on a text box while its shape layer is active, you'll get a new menu item to begin editing that text. (This also works for Circle and Path text as well).
  • Flipping layers horizontal or vertical is more consistent between shape and bitmap layers.
  • Web Export now has an option to include your image's DPI.
  • When saving a TIFF file, Acorn will now use the original compression settings for that file, instead of defaulting to LZW.
  • When saving as a TIFF file, Acorn now gives you options for the compression: LZW, None, and Packbits.
  • New preference for whether or not to change the canvas background color during full screen.
  • New Rotate filter, which works on your image and generated filters. It's non-destructive, so you can always go back and change the angle later on.

# Shape Layer Stuff

  • New: Text boxes can now have a background color and stroke. The text inspector now has dedicated swatches and toggles for text stroke and fill.
  • You can option-click the p icon in the layer list to disable shape processors. And when this happens, you can interact with shapes on the layer as well (where you previously couldn't when you have shape processors going). Disabling all the shape processors will also do this, but it can be a bit more tedious going this route.
  • You can extend an open bezier path by holding down the shift key with the bezier tool selected, and clicking on the end of a bezier path.
  • Text boxes in shape layers got a bit of an interaction makeover. Editing and selecting text boxes should feel more natural and easy now.
  • More obvious selection bounds when trying to choose a shape to select.
  • Added a little extended handle on selected shapes to rotate them directly from the canvas. Previously, this was done by some invisible handles near the corners (which are still there in case you loved those!).
  • The "Arrange Shapes in a Circle" and "Rotate" processors now let you assign fractional values for the angle and spacing attributes.
  • Tweaks to the Shape Creator Processor, which now allows you to create circle shapes with a radius of .5. This is awesome if you're looking to make a star field of some sort. This processor will also automatically turn on fill for shapes, if the shape palette has both fill and stroke turned off.

# Other Notable Quality of Life Improvements and Miscellaneous Things

  • Acorn plays nice with the System Preferences General settings for opening windows in tabs and such.
  • New Fussy Pref: Copying selection trims transparent pixels.
  • New fussy preference: "Use system color panel", which uses the system color panel. You can also hold down the command key when clicking a color well to temporarily use the opposite of whatever this preference is set to.
  • Double clicking on the canvas zoom scale slider will zoom the canvas to 100%.
  • You can now change the color of the canvas background via the canvas's contextual menu (or the command bar).
  • Pressing the '`' (back-tick) key when using a brush or pencil tool will turn it into a temporary eraser. Previously you would hold down both the command and option keys together to get this behavior, but another big image editing app uses '`' so I figure Acorn should too.
  • If you have a color on the clipboard, pasting it into a bitmap layer will now fill it with the color. If you paste this color into a shape layer with selected graphics, it will set the fill color for those graphics. (Did you know: you can use the color picker loupe to put a color on the clipboard by pressing the 'c' key).
  • The layers list was completely rewritten to use modern APIs. Let us know if you notice any chance behavior!
  • The Hard Mix blend mode has been changed to more match the industry standard for this compositing operation.
  • Quartz Composer filters are no longer supported.
  • Using Edit ▸ Copy when multiple layers are selected will now place a composite of the selected layers onto the clipboard, as well as respecting the current canvas selection.
  • Auto-select layer tweaks: If you have the preference "Auto-select layers" under the Advanced tab turned on, Acorn will automatically select a layer for you when you use the move tool to click down on the canvas. If you hold down the command key, then this setting is ignored. Conversely, if you have it turned off and you hold down the command key Acorn will auto-select a layer for you.
  • Smart layer export settings will now reposition themselves when a layer or image is cropped or resized or canvas flipped.
  • Fixed some instances where you could modify a locked layer.
  • You can no longer rotate the canvas if there are locked layers.
  • The ruler now shows a accent color when you're moving selected shapes around, representing the selected shape bounds.
  • Acorn will no longer highlight shapes when you're hovering over a guide.
  • You can now drag and drop an app onto Acorn to open up an image with the app's icon.
  • Acorn will now show the startup window on reopen events if no windows are open and if the preference "Show startup window on launch" enabled.
  • Copying a selection on a bitmap layer now applies the mask before the image is written to the clipboard.
  • Holding down the option key when selecting a color profile from the Preference's default Color Profile for New Images popup will show the full path for the profile names. This is handy if you have multiple copies of sRGB installed, or any other profiles, and you'd really like to make sure you know which one you're using. This also works for the Image ▸ Color Profile… sheet, as well as the RAW Image import window.
  • Improved pasting of multiple objects from one shape layer to another shape layer in another document.
  • Acorn will no longer highlight shapes when you're hovering over a guide.
  • Removed the pref for the "old brush engine". You can use the default 'defaults write com.flyingmeat.Acorn7 useBrushEngine5 1' to bring it back if you really really want it.
  • New Fussy Pref: "Zooming a window fits to current canvas".
  • The exposure filter now uses percentages.
  • Acorn will now keep you from dragging layers out of locked groups.
  • Fixed a problem where various tile filters weren't updating the whole layer when you drew on them
  • Made the filter sheet picker a bit taller
  • You can now make the grid spacing up to 10,000 pixels wide for the canvas. The spacing slider also uses an exponential transformer now, so you can get way larger values now.
  • The canvas scale slider now uses a bit of mathematical magic to make it easier to zoom waaaay in and out.
  • Holding down the control key while dragging a canvas guide around will temporarily turn off snapping (and this trick works with most objects on the canvas too).
  • Take layered screenshots is now on by default when using Acorn's screenshot hotkey.
  • If a brush cursor is less than 5px wide on a retina display, or less than 3px on an @1x display, Acorn will now show a little crosshair because those brushes are otherwise too small to see.
  • You can no longer mess with layer filter settings if a layer is locked.
  • The export window will now auto-select the original color profile for an image, even if it was converted from a gray to an RGB color space. This is awesome if you open up a gray profile image (which Acorn doesn't support for editing normally) and you want to save it back out as the original.
  • Changed the screenshot shortcut key to Command-Shift-7, so it no longer interferes with the system one for taking screenshots of the Touch Bar.
  • Changed the default radius of the color loupe to 200pts (down from 400). If you would like the larger size back, you can paste the following into and hit return:
    defaults write com.flyingmeat.Acorn7 colorLoupeRadius 200
  • Acorn no longer supports plugins written in Python.

# Scripting

  • The JavaScript interface has changed quite a bit. The CocoaScript / JSTalk preprocessor has been deprecated and the [] syntax is no longer encouraged. In fact, your script will fail using this syntax unless it ends with .jstalk or .coscript. JavaScript files that end with .js will no longer be preprocessed. (Though there is a hidden preference to always enable it: defaults write com.flyingmeat.Acorn7 preprocessJS 1
  • The Cocoa Script / JSTalk bridge has been replaced with FMJS. If you have complicated JavaScript files, you might need to rework them a little bit.

Auto-update to test releases (newest, super fun development releases)
Auto-update to regular releases (boring old production releases)

Retrobatch Release Notes

Retrobatch 1.4.5 , 2021.
  • Fixed a problem where undo/redo could be a little wonky.
  • Fixed a problem where Instant Alpha for 64bit images wasn't as smooth as it could be.
  • Fixed a problem where the $FileNumber04$ token wouldn't always work as expected in the write node.
  • Fixed a problem where sometimes converting a PNG to a GIF would fail.
  • Fixed a problem on MacOS Big Sur where Apple Events via Automator were sometimes sending weirdly formatted URLs to Retrobatch and it was unable to process the event correctly.
  • Thumbnails for 16bpc images are now showing again if you're using MacOS Monterey (it's disabled on 10.15 / 11 because of a big memory leak in the system frameworks, which is now fixed in Monterey).
  • Added a new "ExifAux" group for the Remove Specific Metadata" node.
  • New hidden pref for keeping around the portrait and depth data from HEIC images when you write them out as JPEG or other file types:
    defaults write com.flyingmeat.Retrobatch keepDepthData 1
    Should this be a new node? Or maybe an option in the write node? This is a fun hidden pref to experiment with, but it'll probably change in the future.
Retrobatch 1.4.4 May 1st, 2021.
  • Fixed a problem for MacOS 10.15.7 where the April 26th security update from Apple made Retrobatch unable to render anything via Core Image.
  • Double clicking on the workflow name in the toolbar will now zoom the window.
  • Folks on MacOS 11 will get an updated icon.
  • Fixed an issue where using $IPTCKeywords$ for the Set Finder Tags node would only use the first keyword as a tag. Now it adds all keywords as tags.
Retrobatch 1.4.3 November 13th, 2020.
New Stuff
  • Retrobatch is now a Universal Binary, running natively on the new Apple Silicon Macs.
  • The Rotate node has a new "Cumulative" option. This is awesome if you have an image you'd like to duplicate a bunch of times and then rotate by a little bit more each time, and then write it all out.
  • Added two new sort options for the Read Folder node: Full input path, ascending / descending.
  • Added a new node "Alpha Multiply" which can increase or decrease the values in an image's alpha channel (Pro only).
  • The preview view does a better job at keeping the current image zoom level when cycling between preview images.
  • The Image Grid node bumped up the count of images you can have in a row or column from 100 to 1000.
  • New behavior for droplets: droplets made with Retrobatch 1.4.3 or later will now wait a second after processing images to quit, just in case a 3rd party workflow or script decides to send it more images to process. Previously, a droplet would ignore any additional images added to it, and instead quit after it's first batch of images were processed. Now it'll stick around and process any more images it has been given before quitting.
  • When using Retrobatch from the shell, any input files or folders are now sorted alphabetically before processing.
  • Fixed a problem where Retrobatch would have a bad time if there was an empty IPTC Keywords field in the "Set Specific Metadata" node.
  • Fixed a problem where Retrobatch wouldn't be able to correctly trim images with a non-RGB color profile.
Retrobatch 1.4.2 August 6th, 2020.
New Stuff
  • New "Truncate JPEG Data" node, which will remove empty data at the end of JPEG files which could be introduced when transferring files off of an iOS device.
  • New Premultiply and Unpremultiply nodes for Retrobatch Pro, which multiply (or divide) the image’s RGB values by its alpha.
  • Support for reading and writing Google's WebP image format.
  • Now clearing the image classification cache when a workflow is closed. This slows things down on the next open and run of it, but uses less memory in the long run.
  • Fixed a problem the Adjust Margin nodes would stop all processing from continuing when it was disabled.
  • Fixed a problem where the palette for a selected node would not be removed when the node was deleted.
  • Fixed a crasher in some cases when undoing a node added to the canvas.
  • No longer showing the file proxy for unsaved workflows.
  • The file path popup in the toolbar now behaves 14% more like the OS equivalent.
  • Added a new JavaScript plugin API for getting an image's bitmap as a typed array. You can read about this in the JSAPI documentation.
  • Did a bunch of internal plumbing on the JavaScript interface to get it ready for the new Apple Silicon Macs.
  • Tweaks to the Instant Alpha node, so that it works better on ARM Macs. (And we've got Universal builds of Retrobatch available as well. Known issue: the Animate node isn't available).
Retrobatch 1.4.1 April 2nd, 2020.
  • Fixed a problem where some JavaScript plugins stopped working.
  • Little tweaks to the Prompt for Files node to make sure it gets called before the Write node asks you for a place to save images.
Retrobatch 1.4 March 31st, 2020.
New Stuff
  • New Overlay node, which allows you to set a background image to draw all your workflow images above. You can adjust scale, placement, opacity, blend mode, and more.
  • New "Run Workflow for Previewing Image" menu item, which will process only the current image you are previewing through your workflow. This is super awesome for complicated workflows that you can't always get an accurate preview for, or for workflows which run scripts in the background.
  • JavaScript expressions in Retrobatch Pro. Various nodes which allow you to set the size or length of a value (such as the Crop, Border, Gradient, Adjust Margin nodes) now have an option of running a little snippet of JavaScript code to figure out the value. This is a super powerful feature, which you can read about in our JavaScript Expressions documentation.
  • New Oval Matte node, which will place an oval over your image (matching the bounds of your image) and fill the outside with a color of your choosing.
  • New Crop to Face node. Does what it says on the tin. Finds one or more faces, and crops your image to the bounds found, with options for adding margins on the sides.
  • New Make Square node. This node will make the width and height of your image the same, optionally making it bigger by expanding the margins, or by cropping it.
  • New Adjust Margins node. This node will let you add or subtract pixels to the edges of an image, and with an optional border to fill in the pixels if you make your image larger.
  • New Mask to Alpha invert colors option. Normally mask to alpha will convert the black areas of your image to transparent, and the white to opaque (with gray somewhere inbetween). With the new Invert Colors option, Mask to Alpha will now convert the white areas of your image to transparent, and keep the black opaque. This is great if you are scanning in line drawings from your own artwork, and want to make the backgrounds transparent.
  • File numbers with leading zeros in the Write node tokens. We've not yet added a UI for this, but you can add (and it's case sensitive) $FileNumber04$ in the File name: field of the Write node to have the file number of your image written out as part of the name, with a padding of up to 4 zeros. If you'd like to pad that number to 6, you would enter $FileNumber06$, and so on. Negative values won't work! And asking for values over 100 is asking for trouble, since MacOS will be angry with you and not allow it.
  • Minor update to new droplets- you can now have a droplet which doesn't take any files. Why is this useful? Well, imagine you have a workflow that reads an image from the clipboard, resizes it to a specific width, and then writes it back to the clipboard. Now you can save your workflow to do just this.
  • Fixed a problem where the Clipboard IO node could cause a crash in certain circumstances.
  • Fixed a problem where the file count for the Read Folder node wouldn't update on the canvas when the "Include images in subfolders" option was toggled.
  • The Image Grid node now takes out images from the preprocess stage which would otherwise be combined with other images in the grid. This means the canvas file count previews are now more accurate.
  • Fixed a problem where changing values in the Image Grid node would sometimes not stick if you were quickly tabbing between the fields.
Retrobatch 1.3.1 January 1st, 2020.
New Nodes
  • False Color: False color is often used to process astronomical and other scientific data, such as ultraviolet and x-ray images.
  • X-Ray: Applies an X-Ray style to an image.
  • Fixed an issue where animated PNGs and GIFs were not being properly created.
  • Fixed an issue where the Prompt for Files node wasn't processing images in ascending order.
  • You can set the FPS per image frame using the following code snippet in a JavaScript node. The JavaScript node should be placed before the Animation node.
    function processAsset(document, jsnode, asset) {
        // Set the FPS of this frame to something between 0-60
        asset.setUserValue_forKey(Math.random() * 60, "animationFramesPerSecond");
        return true;
Retrobatch 1.3 October 17th, 2019.
  • New options in the Trim to Edges node: Trim by transparency, selected color, or the edge color of an image.
  • New "Page Number" token for the Write node, which can be used as a path token (or for the name) when writing the image. The value of this token is incremented when a multi-page image or an animated image is passed through the "Layer and Page Splitter" node.
  • New "Source Folder Path" token for the Write node, can be used to write an image back to the same folder it was read from. The the token "Source Folder" has been renamed to "Source Folder Name".
  • The Add Border node now lets you set the width of the border as pixels, percentage of width, height, short side, or long side.
  • You can now set a target megapixel value for the scale node. So if you want all your images to be 12MP, even they all have different aspect ratios, you're now set.
  • New Remove Specific Metadata node for Retrobatch Pro.
  • New Linear and Radial Gradient nodes.
  • New Vignette node.
  • New option in the Write Node which asks for an output folder on every execution, meaning you don't need to have it set before running.
  • New "Duplicate" node, which takes a single image, copies it, and sends it on to the next node(s) for each copy. You can combine this with the Tile node to repeat an image multiple times into a bigger image.
  • The image info popover now shows a page number, which is helpful for figuring out which frame or page an image came from when split from a PDF or animated image.
  • Set Specific Metadata node: You can now set multiple keywords using the IPTC:Keywords field by separating keywords with commas.
  • Shell Script node improvements: If the output from your script contains a line that starts with outputImagePath: followed by a path to a valid image, that image will be used for the rest of the workflow.
  • More Shell Script improvements: You can return image data from a shell script if the output of your script is 'imageData:' followed by a newline, and then valid image data to read in.
  • Made some improvements to the PDF maker node, so that if you are splitting pages from a PDF and then stitching the back together, the original PDF data is used. This means if there's vector data, it's not rasterized to a bitmap. This will only happen as long as no nodes have modified the page data in-between it being split and and stitched back together.
  • Fixed color drift via the color picker when certain ICC Color Profiles where selected.
  • Fixed a problem where tiling images that had been processed with the grayscale node wouldn't work properly.
  • Fixed a problem rendering PDFs with special transforms in there (like the Special Counsel report!).
  • Fixed a problem when writing a depth map extracted from an image as a PNG.
  • Minor fixes with the Image Grid node.
  • Added a description to the Animated Image node.
  • Minor 10.15 Catalina fixes.
Retrobatch 1.2 April 2nd, 2019.
  • New Animated Image node, which will allow you to make animated GIF or PNGs.
  • Droplet support! Use the File ▸ Save As Droplet… menu item to write out your workflow as an application, which you can then drag and drop folders and images on to run your workflow. To re-edit a workflow contained in a droplet, you can either hold down the Option key when opening the droplet, or drag and drop the droplet onto the Retrobatch app icon.
  • New Set Finder Tags node, which can assign one or more tags to images in the Finder (Pro only). This will work on the image that was most recently written- so you don't need to write out a copy of an image to set it. You can instead have a Read node, and then a Set Finder Tags right after it and Retrobatch will then set the tags on the original files.
  • The Clipboard node got some improvements:
    • It will now notice when a new image shows up on the clipboard, and update the preview accordingly.
    • If you copy a file in the Finder, it'll now use that file on disk to process through any following nodes.
  • New preferences for sending out a notification when a workflow ends, as well as playing a sound.
  • The Watermark node now has a "File Number" token, which is the image number being processed.
  • The Shell Script node has a new field where you can enter arguments to the selected script. Arguments are separated by spaces.
  • New "Round Corners" node.
  • New "Limit" node which will limit the number of images or PDFs allowed to pass through (Pro only).
  • New "Image Grid" node.
  • New option for the Write Images node, which enables to you write your processed images back to the original image it came from.
  • New template "Classify and Set Keywords" which uses Machine Learning to figure out what's in the image, and sets the metadata keyword based on what it found.
  • New "Page Number" rule in the Rules Node. You can use this rule to say "only let the first page of a PDF through", or "all pages of an animated GIF except the first", or even limit images 5 though 16.
A New JavaScript Node Plug-In API for Retrobatch Pro (Beta!)
  • You can now write and distribute custom nodes in JavaScript using a new Plug-In API. This feature is currently in beta, and we're hoping to finalize it in a future release. But it's already incredibly useful today. If you have questions or ideas, head on over to the forums to ask about them and don't forget to read a short introduction on how to create one.
  • In addition, the CocoaScript bridge has been replaced with FMJS. No changes to current scripts should be needed.
  • Fixed some problems previewing images created from the clipboard.
  • Fixed a problem when changing the DPI of PNG images when no new image bits were written (just metadata changes).
  • Fixed a problem where using Automator to run a workflow wouldn't always process images through all the connected nodes.
  • You can now rename RAW files without having to re-encode them with the write node, as long as there are no changes to the pixels made in the image.
  • Fixed a problem where you couldn't select PDF files along with images from a couple of Open panels.
  • Squircle instead of circles for the node shapes on the canvas.
  • Retrobatch is now notarized from Apple. We're not sure what this does for you, but your Mac would eventually complain if we hadn't. Hurray!
Retrobatch 1.1.1 January 23, 2019.
  • Create indexed PNG files with the a new "Indexed PNG" node. This node builds on top of pngquant, which is a handy tool for reducing the number of colors in a PNG file resulting in smaller images.
  • New node for Retrobatch Pro: Mask to Alpha, which converts grayscale images with blacks to transparent and keeps the white areas opaque.
  • MacOS 10.13+: A new "Extract Disparity Image" node which will pull out a disparity map images which contain it (iPhone X(s), iPhone 8+, etc.)
  • MacOS 10.14+: A new "Extract Portrait Matte" node which will pull out the portrait matte on images taken iPhones which support it (iPhone X(s), iPhone 8+, etc.)
  • Fixed a problem where the DPI of a PNG would be lost when using the Crush option in the write node.
  • Fixed a problem where Retrobatch could crash if a text watermark font previously used went missing.
  • Fixed a problem where the Page Splitter node wasn't remembering the right DPI for TIFF files.
  • Fixed a problem with the HEIC to JPEG template.
  • Fixed a problem where Retrobatch wouldn't run via the command line tool correctly.
  • Fixed a problem where Retrobatch could hang when running via Folder Actions.
  • The scale node now takes decimal values for the scale as percentage field.
  • Removed the "ImageAlpha" node, in favor of the "Indexed PNG" node.
Retrobatch 1.1 September 7th, 2018.
  • Automator support. You can now create an Automator action which runs a workflow, passing in image paths to the workflow to run. You can even make a droplet from your Automator action.
  • New Instant Alpha node which removes pixels from your image based on a sampling location like the corners or center of your image.
  • New Auto Enhance node, which does some black magic to make your photos look better.
  • New preference for manual connections (control-drag to make connections between nodes).
  • New JavaScript node (Pro only) where you can sort out images, print out information on images, or apply Core Image filters. Visit the JavaScript documentation for more information.
  • New Dither node with Atkinson, Classic Mac, Floyd Steinberg, Gaussian Blue, and Ordered Reproducible algorithms.
  • New "Only scale smaller" option for the Scale node, which will only resize your images to a smaller dimension if the option is enabled.
  • The "Set Specific Metadata" node now allows you to use tokens for setting various values. For instance if you wanted to have the copyright notice set to the current year, you would add "Copyright (:date token here:)". Or if you wanted to pipe the image through a classification node before the metadata node, you could add the "Top Classification" node to the keywords field.
  • New "PDF Image Extractor" node (Pro only). This doesn't turn PDF pages into bitmaps, rather it pulls out bitmaps from PDF files and writes them out either as JEPG or PNG files. A PDF page can have multiple images in it, each at different resolutions. This node grabs the raw data for it, and pulls it out.
  • You can now call Retrobatch from the command line, with arguments for a workflow, output folder, and images / folder to process: --workflow path/to/workflow.retrobatch --output ~/Desktop/foo/ /path/to/files.jpeg /or/folders/
  • Added GIF as a writable format in the write node.
  • The Raw Import node now has an option to adjust the tint of your image.
  • Added a Color Posterize node.
  • Added a new Pixel Depth token for the file name.
Changes and Fixes
  • The shell script node now shows the output from the scripts in a new little console window. The new JavaScript node also uses this.
  • Did a bunch of background work which will make Retrobatch run more efficiently when preprocessing.
  • Minor fixes to the Raw Import node.
  • Minor optimizations.
  • Fixed a crasher when running non-executable shell scripts.
  • Fixed a crasher when using trim to edges on images with a gray color profile.
  • Fixed a problem where you couldn't paste into token fields (such as the File name: field in the write node).
  • Fixed a crasher with the Shell Script node.
  • Fixed a crasher when using certain classification models.
  • Fixed a problem where you could choose a file from the Write node as an output directory. That's not going to work in practice and probably cause a crash.
  • Fixed a problem with certain PDFs, when creating an image out of the first page.
  • Tweaking of the Scripting Dictionary, so you can call "execute" with a path to a workflow.
  • If you run a PDF through a Color Profile node before passing it to a Layer & Page Splitter node, the page bitmaps created from it will now pick up on the previously set profile. This way you can have all pages written out as CMYK if you'd like, without an expensive and lossy conversion after the split.
Retrobatch 1.0.2 June 21st, 2018 (happy summer solstice!).
Changes and Fixes
  • Fixed some bad juju between the PSD Maker and the Write Node when the Convert To was set to PSD.
  • Retrobatch's AppleScript node now recognizes compiled OSA ".scpt" files in addition to .applescript files.
  • Fixed a problem where "Reveal in Finder" wouldn't work on an image after it had passed through the ImageAlpha node.
  • When the read folder is set to be recursive, it will now make sure the images are written out in the original folder structure that they were read as. If you were using the "Source Folder" token in the write node, you might need to remove it for things to work as they did previously.
  • Retrobatch will now try and recreate write folders if they've been deleted while Retrobatch wasn't running (this will require a re-save of your Retrobatch documents with version 1.0.2).
  • Fixed an issue with Pro upgrade registrations not working correctly.
  • Added a warning when the tokens used in the File name field for the write node come up empty (for instance, if you had a Capture Date token in the file name, but there was no date for the image, so the filename would be blank).
  • Throttling the thumbnail loading background thread a bit, since it turns out some of you have folders full of 100 megapixel images and that tends to kill your computer if you try and load thumbnails for 16 of those images at once.
  • Added new Edit ▸ Select Next Node & Select Previous Node menu items, which helps with Accessibility as well as everyone in general.
  • Added support for Voice Over.
  • Fixed a problem where older macs without Metal support might not see the image preview.
  • Fixed a problem where images with indexed color profiles couldn't be resized.
Retrobatch 1.0.1 June 1, 2018.
Changes and Fixes
  • Fixed a couple of memory leaks.
  • Fixed a problem where empty file name tokens in the write node could cause Retrobatch to crash.
  • Retrobatch now accepts upgrade registration numbers from regular to Pro.
Retrobatch 1.0 May 29th, 2018.
  • Hello world.
