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.

Return Values

The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
