Acorn 3.5 – Bitmap image editor.

Acorn
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.
  • Gradients.
  • 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.


What’s New

Version 3.5: New Stuff:

  • The magic wand selection tool now has an option for contiguous or non-contiguous selections. In addition to this, if you use the magic wand tool on a shape layer with the contiguous option turned off, it effectively works as a "select all shapes with this fill color" tool. Which is pretty rad if you have a bunch of shapes that you want to change the colors on.
  • New File -- Layer Export… menu item, which will export a single layer out of Acorn. In addition to this, if you have a shape layer that you want to export and it doesn't have any layer styles associated with it, a pure vector PDF will be written out.
  • The contextual menu now has a copy of the Layer -- Shape Align and Size menu for working with selected shapes quickly.
  • New layer blend modes: Divide, Lighter Color, Darker Color, Hard Mix, and Subtract.
  • New Generator -- Sunburst filter, which lets you make some awesome backgrounds.
Changes:
  • Guides are now drawn when you free rotate your canvas.
  • In the Image Browser window (which you can open via File -- Open Folder… menu item), the little icons on either side of the zoom slider will now increase or decrease the zoom level of the preview images when clicked.
  • The "Open Image in Acorn" service will now work with selected files when used from the Finder.
  • If you're editing a file with Autosave + Versions turned on, and that file happens to be locked, Acorn will no longer warn you to duplicate it if you're only applying selections (which don't alter the image).
  • Holding down the shift key while rotating when using the Layer -- Rotate and Transform -- Scale and Rotate menu item will snap the rotation to 45° increments.
  • Increased the amount you can magnify an image with the zoom slider from 1000% to 2000%, which should help out Retina MBP owners. Pro tip: did you know you can click the little icons on either side of the slider to zoom in or out in a controlled fashion? And the zoom tool (shortcut key 'z') can zoom in even more than the slider!
  • Remove FXG as an exportable image format, since Adobe seems to have abandoned it.
  • Pressing the return or enter key on a shape layer no longer merges it down. Why did Acorn ever do this? I wish I knew, but it was on purpose.
  • Slight change in behavior with Image -- Trim to Edges: If a bitmap layer has pixels outside the canvas bounds, they are no longer taken into account when trimming down the size of the image.
  • Added a new property for JSTalk/JavaScript filters to show up in the Actions menu: set ACIsAction=true in the header section of your script.
  • Updated the JSTalk/JavaScript plugin to work on Group layers.
  • The "Plus Lighter" blend mode was renamed to "Linear Dodge", to more closely match other image editors.
  • The "Plus Darker" blend mode was renamed to "Linear Burn", to more closely match other image editors.
  • The blend modes were reordered to more closely match other image editors.
New Stuff for Scripters:
  • Some new plugin APIS:
    • A new method on CIImage: - (BOOL)writeToURL:(NSURL*)fileURL withUTI:(NSString*)uti
    • A new method to implement for the ACPlugin protocol- (NSNumber*)validateForLayer:(id)layer;
    • A new method for finding the opaque bounds on layers: - (NSRect)opaqueBounds;
  • You can also now mess with a layer mask with these new methods on ACLayer:
    • (void)setLayerMaskImage:(CIImage*)ciimage;
    • (id )mask;
    • (BOOL)maskIsLinked;
    • (void)setMaskIsLinked:(BOOL)value;
  • The plugin SDK has been moved to GitHub as well: https://github.com/ccgus/AcornSDK
Lots of Important Fixes:
  • Fixed a bug where sometimes the extension for your filename would disappear in the save sheet.
  • When using the various transform tools on a bitmap layer, the transform operation will now apply to the layer mask if it is linked.
  • Fixed a bug where sometimes text boxes would not get their line heights correctly scaled when resizing an image.
  • Fixed the little Purchase menu blip that you'd sometimes seen when starting up even though Acorn was registered already.
  • Various fixes with the magic wand tool, including little speed improvements.
  • Fixed a bug where you'd get interesting patterns in your selection in some cases with the magic wand tool.
  • Fixed a bug where Acorn thought it would sometimes still have a selection when using the magic wand tool + intersection selection mode, where no intersection was produced.
  • When exporting as PDF, Acorn will now create a document which respects the current DPI of the image.
  • Fixed a bug with the Scale and Rotate transform tool, where you couldn't enter fractional values for the rotation field in the palette.
  • Fixed a bug with the Add Border to Layer filter with Retina displays.
  • Fixed a bug where zooming with the scroll wheel (hold down the option key for this!) would put the canvas in unexpected locations on retina displays.
  • Fixed a bug where using the Scale And Rotate menu item on an even width/height image with a rotation of 180° would offset the image by 1 pixel.
  • Fixed a bug where using the Edit -- Fill menu item to fill your image with a pattern would blur the pattern image.
  • Fixed a bug in Web Export where the Save button wasn't enabled right away if you switched from saving as a PNG to a JPEG while the PNG was still being processed.
  • Fixed a bug where the File -- Add Images… menu item would let you select a PDF, but wouldn't actually import it as a new layer to the image.
  • Using the tab key to change fields in the Acorn Automator Crop Image Action (say it five times fast!) will no take you to the next field.
  • Fixed a bug where sometimes flipping a layer vertical or horizontal would trim out some of the pixels.
  • Fixed a bug where the trim bounds of a shape layer was sometimes wrong with multiple shapes.
  • Various Retina display fixes with layered screenshots and zoom to fit, among other miscellaneous things.
  • Fixed a bug where the file extension would not change correctly when changing the filetype in the Export sheet.
  • Fixed a bug where Acorn would crash when making a new document if there was bad data on the clipboard.
  • When duplicating a document, Acorn will notice if the rulers are showing and turn them on for the duplicated document if needed.
  • Fixed a bug where Acorn wasn't auto-registering from MAS versions of Acorn that were sandboxed.
  • Fixed a bug with the "New Image with Curved Drop Shadow" plugin on Retina MacBook Pros.
  • Fixed a bug with Trim to Edges, where sometimes the canvas would grow if a layer extended outside the bounds of the canvas.
  • Fixed a crasher when web exporting a completely transparent image with the trim and matte buttons checked.
