Acorn 4.5.5 – Bitmap image editor.

Acorn 4.5.5

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 4.5.5:

New Stuff
  • Acorn now comes with a share extension for 10.10 Yosemite, so you can copy images from Photos to Acorn.
Fixed Stuff
  • Fixed a bug where drawing with opacity with the brush tool after clearing a canvas selection wouldn't work properly.
  • Fixed a bug where the opacity slider would sometimes be disabled when you turned off visibility for the non active layer.
  • Fixed a preview issue with the CIVignette filter.
  • Fixed a preview issue with the BC Vignette filter from the BC Image Units package.
  • Fixed a redraw issue with the burn tool.
  • Fixed a bug where moving to a shape layer's mask would clear the current bitmap selection.
  • Fixed a bug where control clicking on a guide didn't always add "Delete Guide" to the contextual menu item (you had to be _right_ on the sucker).
  • Fixed a bug where creating a bezier path with mitered joins wouldn't always draw correctly with extreme join angles.
  • Fixed a bug where using the boolean operations from the quick config popover wouldn't disable after use (since you would only have a single shape selected at this point, and they wouldn't work).
  • Fixed a problem where the ruler wasn't showing the correct origin in the y axis on retina displays.
  • If you're running 10.10.3 or later, you'll get to use the very latest non-buggy version of the RAW importer (version 6) if available for your RAW images.
