5.1 Public Interface


5.1.1 Ordinary functions

Function: render (data-stream &key byte-order)

Given a GIF data stream, returns a rendered image.

The BYTE-ORDER keyword argument is one of :ARGB or :BGRA. It states the order of bytes in the resulting vectors.

Three values are returned.
The first value is a list of vectors containing resulting ARGB data in row-first order and each second element
The second value is a list of integer values for the frame delays in milliseconds.
The third value is a list of three values: image width, image height and a generalized boolean signifying if the GIF should loop.
