- Description
- 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.
- Bie (JBIG) is an image file format that uses data compression to reduce files sizes while retaining image quality. It is commonly used for faxing and is also used in digital image capture and printing.
