Message-ID: <90081.233843BRAUN@FRECP12.BITNET> Date: 23 Mar 90 03:38:43 GMT Lines: 11 Organisation: ECP-Paris France I'am trying to do a program in vspascal to decode gif pictures. I have 3 questions ... * My first question is : did anyone already write a program in pascal for decoding gif pictures ? (it will help me and save my time | ) * The second question is more precise : i have trouble locating the IMAGE DESCRIPTOR, wich is supposed to begin with the '2C'h byte * The third question is about the SCREEN DESCRIPTOR : what is the CR field (bits 4 to 6 in the 5th byte of the image descriptor) Thanks in advance Daniel
