Image File Header Formats

BMP, PCX, JPEG, FLI/FLC, and AVI files include headers that define the image size, number of colors, and other information needed to display the image. Fastgraph provides functions for reading the image headers and retrieving their more useful items. However, there may be times when you need additional information stored in the file header. This section provides full details about the structure of the image file headers. In the tables that follow, we'll assume all offsets start at zero, all field sizes are in bytes, and all numeric values are stored with the least significant byte first.
