Acorn is a new image editor built with one goal in mind – simplicity. Fast, easy, and fluid, Acorn provides the options you’ll need without any overhead. Acorn feels right, and won’t drain your bank account.
- Take screenshots using Acorn and edit them right away.
- Chain together image filters to create stunning effects.
- Layer based image editing, an industry standard.
- Make new images and layers using your built-in iSight.
- Easy image and canvas resizing, just by changing the size of your window.
- Take advantage of every pixel of your monitor with full screen image editing.
- Tablet sensitive for pressure strokes and using the tablet’s eraser.
- Vector shape and text layers.
- Freeform, elliptical, rectangular, and magic wand selections.
- Create and apply custom text styles.
- Control opacity and blending modes for each layer.
- Write plugins using the Python scripting language, as well as in Objective-C.
- GPU powered. The same graphics card that makes your gaming experience smooth, helps Acorn fly through the toughest of graphics operations.
- A New "Radial Gradient Blur", which is sort of a like a vignette, but with a blur. It's awesome, try it out.
- You can now change change the depth of an image to 16 bits per component with the Image ▸ Image Depth menu item. Hello deep images!
- RAW files are now opened as 16 bit per component / 64 bit pixel images.
- The default color profile has now been changed to sRGB. (You can also change the default profile in Advanced prefs).
- All drawing is now going directly through OpenGL, which makes things quite a bit faster.
- You can now cycle through a layer's blend modes with Option Shift + or Option Shift - keyboard shortcuts.
- You can now share images with Flickr, Twitter, Facebook, iPhoto, Aperture, and other services using the File ▸ Share menu item.
- The Gaussian Blur filter now has a popup menu item to choose between clamping, blending, or doing nothing when blurring your image.
- The smudge and clone tools no longer share brush sizes with the burn and dodge tools.
- The pencil tool has been revamped with pixel editing in mind, making perfect squares to help you make perfect pixel art.
- You can now set the blend mode for the pencil tool, and in addition to this there's a new "Copy" blend mode for the pencil tool which will replace the brushed pixels with the selected color exactly, instead of blending (which is awesome if you're using a color with alpha in it).
- The eraser tool now has a softness option, which replaces the antialias checkbox.
- The brush slider now grows and shrinks in size at a manageable yet very nice speed when you scrub back and forth.
- The crop palette now has an option to keep the aspect ratio of your crop bounds when saving a new preset.
- Added a new menu item to flatten all layer styles/filters in a document. Open up the Layers menu, hold down the option key, and the "Flatten Layer Filters" menu item changes to "Flatten All Layer Filters".
- The color picker will now pick up alpha correctly if used over an Acorn canvas. The colorspace for the picked color is now calculated correctly as well.
- If you use the arrow keys with a selection (and a selection tool is active) and hold down the option key, Acorn will copy the selection in the direction you press with the keys, thus extending the selection by a pixel (or 10 if you hold down the shift key).
- Minor New Thing: The Levels and Curves now remember their window placement between uses.
- Holding down the option key with a bitmap drawing tool while on a shape layer will now pickup a color from the shape layer.
- The Levels filter got some tweaks.
- Bumped up the max font size from 1000 pt to 9999 pt.
- No longer snapping to the guides if they aren't visible.
- Removed the blend mode option for the grid since it slowed things down too much.
- Using the View ▸ Zoom To ▸ Fit in Window menu item while in full screen will now re-center your canvas.
- Fixed a bug where non-contiguous wand selections wouldn't work right if the target color had transparency in it.
- Fix: When resizing the crop bounds by an edge with the shift key down, it'll now keep it's aspect ration (previously this only worked if you used a corner to resize).
- Fixed a bug where changing the default color profile for new images wouldn't take effect until you restarted Acorn.
- Fixed a bug where the Tilt Shift filter wouldn't draw right when you were making a selection.
- Fixed a bug where using the auto levels button in the Levels window would sometimes cause portions of your image to go black for the preview.
- Fixed a bug where the rect selection would clip sometimes if you were zoomed way out on an image.
- Fixed a bug where using the subtract selection mode would not clear the selection if you subtracted the whole selection.
- Fixed a bug where group layer thumbnail previews weren't drawn tall enough in the layers list when you added a mask.
- Fixed a bug where the canvas wouldn't update correctly when moving 1px high shapes with the arrow keys.
- Fixed a bug where a shape stroke could only be set by pressing the enter key in the shape palette.
- Fix: You can now set the opacity of layer masks.
- Fixed a bug with selecting vertical bezier paths with only two anchors.
