This is why we created Acorn. Add text and shapes to your digital pictures. Combine images together to create your own. Work with layers to touch up your favorites or make something new from scratch. Do all this and more with Acorn.
Palette: All of the tools condense into one easy to use palette to keep your screen uncluttered and inviting. Easily move the palette around if it gets in your way, or press the tab key to make it hide.
Layers: Use layers, layer styles, and blending modes to make the most of photo editing by allowing easy placement of text and other objects without destroying the picture underneath. Layers allow you to try things out, and change your mind later on.
Tutorials and Documentation: Acorn comes with online documentation, tutorials, and a forum, so you don't have to learn by yourself.
Text: Acorn's text tools give you control over text while maintaining an easy to use interface. Everything is in the text palette from bold and italic to kern and ligature. There's even spell check, because we need it. To take it to the next level, convert your text into a Bezier Path. Since Acorn's text tools build on top of Mac OS X's, you get full unicode support, and rich text formatting.
Drawing: Acorn features brushes that let you draw, scribble, and sketch right on your image. Use a track pad, mouse, or even a tablet. Create your own brushes using Acorn's built in brush designer.
Erasing: Powerful eraser tools like Instant Alpha make removing unwanted areas of your image both fast and fun.
Layer Masks: Use layer masks in your image to block out unwanted areas of your image or to expose layers below.
Filters: Acorn has all of the filters you're looking for, and even includes a great interface to chain filters together to create unique effects.
Gradients: Acorn's multistop gradients place endless combinations of colors at your fingertips. Add and remove colors simply by dragging and dropping them in and out of the gradient preview window.
Vector Shapes: Vector shapes let you make squares, circles and lines, but keep the flexibility of changing things later on. Add and subtract points from Bezier paths and rotate your shapes with the flick of a wrist. Acorn makes creating shapes in your image a breeze.
Screenshots: As long as Acorn is open, press the Command-Shift-6 keys while in any application. Acorn will make a screenshot of your entire screen. Your image will be brought into Acorn immediately, ready for work.
Selections: Make different shaped selections, invert them, feather, even add a corner radius. Use Quick Mask for intricate selections. Or, if you're looking to quickly select an entire color, try using the Magic Wand.
Web Export: When you need to get that image size smaller and still looking good for the web, take a look at Web Export. Acorn provides an estimate for the export file size and lets you compare the compressed version to the original.
Photoshop Files: Acorn now offers improved support for loading PSD images, and for exporting your images as layered Photoshop files.
Performance: Acorn goes all the way up to 64. Bits that is. A faster Acorn means less waiting equals more time creating.
Whats New in Version 3.3
For a complete list of changes see the release notes on our website (there's too many to fit in here).
* Retina Canvas and HiDPI Support - Acorn will map a single pixel from your image all the way to your display. No more fuzzy image editing for Retina display owners!
* You can now convert the current selection into a layer mask just by invoking the Layer ▸ Add Layer Mask menu item when your selection is active. Rad.
* Awesome new feature- Reselect! The Select ▸ Reselect menu item will now remember whatever the last selection for your image was. So you can make up some fancy selection, clear it, and then use it again later on.
* New shortcuts for making selections from layers. Holding down the command key while clicking on a layer in the layers list has made a selection based off using the layer image as a mask. Now if you hold command + the shift key, the new mask will be added to an existing selection, command + option will subtract, and command + shift + option will intersect.
* In the resize canvas sheet, you can now use Command 1 through 9 on the number keypad to choose an anchor for the image. Command-1 corresponds to the lower left, Command-9 is the top right, Command-5 is in the middle, etc.
* New iPad presets in the new document window.
* Subtraction and intersection selection modes now works for the magic wand tool.
* The text system got a little makeover so rendering more closely matches what you see when editing a text box.
* You can now close open paths using the Layer ▸ Shape Align and Size ▸ Close Path menu item.
* Command-control-- can now be used as a shortcut to delete the selected layer style in the layer style palette.
* New contextual menu for selected shape layers for Send to Back / Bring to Front.
* The Web Export window now has a scaling option. The AppleScript and JSTalk interfaces have also been updated to take width and height properties.
* Acorn is now sandboxed.
* Various fixes for OS X 10.8 Mountain Lion
* Fixed a bug where the Hue Adjust layer style would show your saved style in radians instead of degrees.
* Fixed a display issue with the ruler when you had units set to Centimeters.
* Fixed a bug where origins on bitmap layers sometimes reset to zero when changing the color profile of the image.
* If you've go the canvas origin set to the top left, then the canvas grid will correctly now set its origin to this point.
**Other interesting tidbits:**
* When trimming an image, the bounds for invisible layers will no longer be taken into account.
* If you start a selection and move the mouse outside the window and stop, Acorn would stop the selection even if you had more room to scroll around in. In 99% of the cases, this isn't what you wanted- so now Acorn will continue scrolling if you stop moving the mouse outside the window.
* Reworked the warning you get when trying to trim an image without any transparent edges. It is now 84% more accurate.
* When merging visible layers, Acorn will combine all the images into a new layer - and now it'll use the name of the selected layer (assuming it's visible) for the new composited image.
* The layer styles fx symbol in the layers list now dims when layer styles are disabled.
* You can now remove a gradient stop-point by moving it off the edge of the preview either left or right, in addition to below as it's always been.
* Flipping a layer in place now keeps it within the layer's opaque bounds.
* When you have a group layer selected and you copy + paste to a new image- instead of a composite of all the images the whole group with layers preserved are pasted.
* You can now use the various selection tools on a hidden layer.
* If you have multiple points selected in a bezier path, pressing the delete key now removes all of them instead of the first one Acorn comes across.
* The formatters in the filter panels no longer use commas in the numbers because that got really annoying.
What's New in 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.
* Mask to Alpha is now available as a new layer style option
* 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.
* 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 have been added- visit http://flyingmeat.com/acorn/releasenotes.html for the full list.
* The plugin SDK has been moved to GitHub: https://github.com/ccgus/AcornSDK
# Lots of Important Fixes:
* 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.
* And more- the whole list is available on our website: http://flyingmeat.com/acorn/releasenotes.html
What's New Version 3.5.1:
* Fixed a bug where drawing with a selection on transparent pixels would come out incorrectly.
* Fixed a bug where the delete AppleScript command wasn't working.
* Fixed a bug where the rectangle selection cursor was showing up in the wrong location.
* Fixed a bug where writing out a WebP image via AppleScript or JSTalk would always make the background black instead of white.
* Fixed a bug where using the Edit ▸ Fill menu to fill a layer with an image would sometimes not fill the entire image.
* Fixed a bug where taking your hand off the shift key when moving multiple layers inside a group layer would cause some to be moved by 10x (with the shift key down) and others by 1x.
* Fixed a bug where a unique combination of clicking the "trim" option in the web export window while also setting a scale would cause your image to be scaled in an odd manner.
* Fixed a bug where setting the opacity for a group layer would incorrectly apply it to layers below it as well.
* Fixed a bug where the View ▸ Zoom in / out menu items wouldn't work on a new canvas view window.
* Fixed problem where a single click with the selection tools wouldn't clear the current selection.
• Fixed a bug where Merlin (the filter HUD) wouldn't always work correctly on first click on the canvas after adding a new filter.
• Fixed a bug where double clicking a text box when you had another shape selected at the same time would cause color changes on all the selected shapes.
• Fixed a bug where RAW import window wouldn't update the image when you typed in values for some of the input fields.
