Acorn 4.0.3

Everyone needs to edit images at some point, but not everyone has the time to learn complicated super pricey image editing programs. 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 favorite photos or make something new from scratch. Do all this and more with Acorn.

New in Acorn 4:
Speed
Acorn 4 is a lot faster than its predecessors. From applying selections and filters to large images to using Instant Alpha, everything is faster.
Non-Destructive Filters
Layer styles and filters are now merged together into a happy new UI. Chain filters together to create endless combinations of unique effects knowing you can always change your mind later on.
Curves
Adjust the tonal response and even the individual color channels to perfect the midtones, shadows, highlights, and contrast in your images.
Multiple Layer Selection
You can now select multiple layers and move, delete, or reposition them all at once.
Boolean Shape Operations
Union, subtract, difference, and exclude. Perform Boolean operations with multiple shapes to make complex vectors in your images.
Merlin HUD
With the new filter HUD, you can now directly manipulate the radius and center points for your filters right on the canvas.
Improved UI
Acorn's tools have been expanded and the tools palette is now a separate window. The windows have even been given a new coat of paint.
New Shape Tools
Stars, Arrows, and a Bezier anchor selection tool await you in Acorn 4. Modify the points of a star to create triangles, diamonds, and other variations!
