An icon is made up of an icon image and a mask that tells the system how to interpret the different areas of icon transparency. Mask-R-Aid is a utility that allows the creation of the mask to be carried out automatically by using three algorithms.
Version 4.0 of the tool includes the possibility of exporting the icons as icns files, as well as exporting the different elements selectively. Additionally, Mask-R-Aid can now save all images and settings to a single file.
Mask-R-Aid requires Mac OS X 10.2 or later and has a license price of $ 15.
