TI Bitmap (86i) is a raster image file format used by Texas Instruments graphing calculators. The 86i format is used to store bitmap images, which are composed of individual pixels with a specific colour and intensity. The file format allows for images to be displayed on the calculators.
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.
