cc [ flag... ] file... -lmlib [ library... ] #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);
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.
The function takes the following arguments:
Pointer to destination image.
Pointer to source image.
X coordinate of the area origin in the destination.
Y coordinate of the area origin in the destination.
X coordinate of the area origin in the source.
Y coordinate of the area origin in the source.
Width of the area to be copied.
Height of the area to be copied.
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
