#include <mlib.h>
mlib_status mlib_ImageCopySubimage(mlib_image *dst, const mlib_image *src, mlib_s32 xd, mlib_s32 yd, mlib_s32 xs, mlib_s32 ys, mlib_s32 w,
mlib_s32 h);
DESCRIPTION
The mlib_ImageCopySubimage() function copies a specified rectangular area from one image to a specified area of another image. The data
type of the images can be MLIB_BIT, MLIB_BYTE, MLIB_SHORT, MLIB_USHORT, MLIB_INT, MLIB_FLOAT, or MLIB_DOUBLE.
It uses the following equation:
dst[xd+i][yd+j][i] = src[xs+i][ys+j][i]
where i = 0, 1, ..., w-1; j = 0, 1, ..., h-1.
PARAMETERS
The function takes the following arguments:
dst Pointer to destination image.
src Pointer to source image.
xd X coordinate of the area origin in the destination.
yd Y coordinate of the area origin in the destination.
xs X coordinate of the area origin in the source.
ys Y coordinate of the area origin in the source.
w Width of the area to be copied.
h Height of the area to be copied.
