static int pcx_rle_encode ( uint8_t *  dst,
int  dst_size,
const uint8_t *  src,
int  src_plane_size,
int  nplanes 
) [static]

PCX run-length encoder.

Parameters:
dst output buffer
dst_size size of output buffer
src input buffer
src_plane_size size of one plane of input buffer in bytes
nplanes number of planes in input buffer
Returns:
number of bytes written to dst or -1 on error
Bug:
will not work for nplanes != 1 && bpp != 8
