In the image below you can see Acorn's canvas. This is where the composite of all your layers are viewed and where you draw, crop, or modify your image in other ways. The bottom portion of the canvas window is called the status bar.
On the bottom left hand side of the window along the status bar you can find the image size. Clicking on the image size label will toggle it between the image size, and the image PPI (Pixels Per Inch). If you have a selection present, this is where you can find its width, height, and x,y coordinates.
The current zoom (or magnification) level, as well as the option to change the zoom using a slider can be found on the bottom right hand side of the window's status bar. To manually enter a specific zoom value, click on the number percentage and an editable field will appear.
The file name and format can be found along the center of the top window bar, and the close, minimize, full screen buttons are at the top left.
Going into full screen mode allows you to expand Acorn to the entire screen. Toggle between regular screen and full screen mode quickly by using keyboard shortcut 'f'. To hide or display the tools palette in full screen mode, toggle the tab key. Move the canvas anywhere in the screen using the pan tool (quick tip- hold down the space bar while using the move tool as an additional way to position the canvas).
