targa_encode_rle()

static int targa_encode_rle ( uint8_t *  outbuf, int  out_size, const AVFrame *  pic, int  bpp, int  w, int  h  )

static

RLE compress the image, with maximum size of out_size.

Parameters

outbuf	Output buffer
out_size	Maximum output size
pic	Image to compress
bpp	Bytes per pixel
w	Image width
h	Image height

Returns

Size of output in bytes, or -1 if larger than out_size
