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
dstoutput buffer
dst_sizesize of output buffer
srcinput buffer
src_plane_sizesize of one plane of input buffer in bytes
nplanesnumber 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
