Definition at line 36 of file pcxenc.c.

pcx_rle_encode()

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
