Function Documentation

int ff_rle_encode ( uint8_t *  outbuf,
int  out_size,
const uint8_t *  inbuf,
int  bpp,
int  w,
int  add_rep,
int  xor_rep,
int  add_raw,
int  xor_raw 
)

RLE compress the row, with maximum size of out_size.

Value before repeated bytes is (count ^ xor_rep) + add_rep. Value before raw bytes is (count ^ xor_raw) + add_raw.

Parameters:
outbuf Output buffer
out_size Maximum output size
ptr Input buffer
bpp Bytes per pixel
w Image width
Returns:
Size of output in bytes, or -1 if larger than out_size
