NAME
mlib_ImageCreateSubimage - subimage creation SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_image *mlib_ImageCreateSubimage(mlib_image *img, mlib_s32 x, mlib_s32 y, mlib_s32 w, mlib_s32 h); DESCRIPTION
The mlib_ImageCreateSubimage() function creates a mediaLib image data structure for a subimage based on a source image. Note that the mem- ory space of the source image data is used for the subimage data. The data type of the image can be MLIB_BIT, MLIB_BYTE, MLIB_SHORT, MLIB_USHORT, MLIB_INT, MLIB_FLOAT, or MLIB_DOUBLE. PARAMETERS
The function takes the following arguments: img Pointer to source image. x X coordinate of subimage origin in the source. y Y coordinate of subimage origin in the source. w Width of the subimage in pixels. h Height of the subimage in pixels. RETURN VALUES
The function returns a pointer to the mlib_image data structure. ATTRIBUTES

NAME
mlib_ImageCopySubimage - copy subimage SYNOPSIS
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); 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. ATTRIBUTES
