- Description
- The ATK (Andrew Toolkit raster object) file type is a raster image format used by the Andrew Toolkit, a graphical user interface development system developed by Carnegie Mellon University. ATK files store both vector and bitmap graphics and are used to create graphical user interfaces for applications.
- An ICO file is an image format used to store icons for Windows programs, files, and folders. It contains two bitmaps: 1) the AND bitmap - the image mask (which determines what part of the icon is transparent) and 2) the XOR bitmap - contains the icon which is mapped onto the image mask. ICO files can be modified to create custom icons.
