Creating, Opening, and Saving Images

Creating a New Image
To create a new image, choose File ▸ New (⌘N) from the menu bar.
You can choose a preset image size, or you can enter your desired dimensions manually.If you are manually entering the dimensions, you have the option to use different measurement values including pixels, inches, and centimeters. You can also select your image resolution and background color.For more information on resolution and PPI, read all about DPI, PPI, and printing.
Creating and Deleting New Image Presets
Bitmap Image Download
To create a new image preset, enter the width and height values into the appropriate fields then click on the preset drop down menu.Choose 'Save Preset'.You will be prompted to give your preset a name.In order to delete a preset you have created, hold down the option key while clicking on the preset name.A window will appear to confirm that you want to delete the preset.You can only delete custom presets.

To open an image, choose the File ▸ Open menu item.You can also drag and drop images onto Acorn's icon in the dock.If you would like to combine two or more images together, use the File ▸ Add Images.. menu or drag and drop your images from the Finder into Acorn's canvas or layers list.If you add a single image via the File ▸ Add Images… menu item and it doesn't fit on the canvas, Acorn will begin a scale and rotate transform for you.The image will automatically be scaled to fit into the canvas.If you want to pop out of the scale, pressing the ESC key will end it.
If Acorn is running and you have an image on your clipboard that you would like to open in Acorn, right-click on the Acorn icon in the dock and select 'New Image from Clipboard', or choose File▸ New from Clipboard from the menu. If you have a https: URL to an image on the clipboard, you can choose File▸ New from Clipboard and the image will download and open in Acorn.
Tip:If you can only see a small portion of your image, try zooming out using View ▸ Zoom Out or dragging the slider found on the lower right hand corner of the window to the left.Alternatively, you can use View ▸ Zoom To ▸ Fit in Window. If you are wanting a specific zoom percentage, click on the zoom percentage number located on the lower right hand corner of the canvas and enter a value.
Saving Images
You can save images by selecting File ▸ Save or File ▸ Save As. When working with an image editor such as Acorn, it is a good idea to always work off a copy of an image rather than the original.When in doubt, select File ▸ Save As and re-name the file so you don't accidentally make permanent changes to your original image!Also, be aware that saving certain file types will 'flatten' your layers so that you cannot edit them easily later.Acorn will warn you if you are at risk of losing your layers when saving, unless you have checked the 'do not show this message again' box.
When in doubt, be sure to save a copy of your file as .acorn.
Autosave and Versions
Using Acorn on OS X 10.7 or later gives you the ability to use autosave and access previous versions of your image using Time Machine.This feature is off by default, but can be enabled in Acorn's Preferences under the General tab. With autosave your changes are saved automatically for you. Versions of your image will automatically be created every hour, and every time you open the file.
To view previous revisions of your file, use the File ▸ Revert To ▸ Browse All Versions… menu item.
You can find out more about Autosave and Versions from Apple: OS X Lion: About Auto Save and Versions.
