Name
MiniGIF
---------------------------------------------------------------------------
Description
The MiniGIF sample application displays GIF images.
GIF decoder decodes GIF89a images to RGB565, BGR565 or a GIFFRame
( actual frame with 8bit color and a color table )
The decoder only supports 8-bit frame output with color table. In order
to include the frame descriptor in output, a special parameter type
PalmCodecGIFFrameParamType is defined.
There is no frame resampling for GIF89a. No matter what width/height is
passed in with PalmImageParamType, it is ignored (each frame has its
own imageWidth and imageHeight).
Passing in (0, 0) for output size will make the codec adjust the
dimension to the global frame size described in GIF header.
The Decoder supports frame-by-frame decoding for GIF89a so the app can
show the animation. Each EncodeDecode() call outputs exactly one frame.
This implies that the output buffer must be large enough to contain one
frame (otherwise there will be an error).
The rest of the details are similar to other Image codecs. Please check
MiniImage sample and readme file.
