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.
The CRG file type is predominantly associated with Calamus, a sophisticated desktop publishing software targeted mainly at professional users. Developed initially for the Atari ST in the late 1980s, Calamus offers powerful tools for layout, text handling, and graphic design. CRG files specifically contain raster graphic data used and generated within the Calamus environment. These files enable users to manage and incorporate detailed graphic elements into their publishing projects, ensuring high-quality outputs for print and digital media.
