Definition at line 38 of file anm.c.

static int op ( uint8_t **  dst,
const uint8_t dst_end,
GetByteContext gb,
int  pixel,
int  count,
int *  x,
int  width,
int  linesize 
)
inlinestatic

Perform decode operation.

Parameters
dstpointer to destination image buffer
dst_endpointer to end of destination image buffer
gbGetByteContext (optional, see below)
pixelFill color (optional, see below)
countPixel count
xPointer to x-axis counter
widthImage width
linesizeDestination image buffer linesize
Returns
non-zero if destination buffer is exhausted

a copy operation is achieved when 'gb' is set a fill operation is achieved when 'gb' is null and pixel is >= 0 a skip operation is achieved when 'gb' is null and pixel is < 0
