[comp.graphics] decoding gif in pascal ?

BRAUN@FRECP12.BITNET (03/23/90)

    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
