mlib_ImageSub2_Inp(3MLIB)				    mediaLib Library Functions					 mlib_ImageSub2_Inp(3MLIB)

NAME
mlib_ImageSub2_Inp - subtraction, in place SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_ImageSub2_Inp(mlib_image *src2dst, const mlib_image *src1); DESCRIPTION
The mlib_ImageSub2_Inp() function subtracts the second source image from the first source image on a pixel-by-pixel basis, in place. It uses the following equation: src2dst[x][y][i] = src1[x][y][i] - src2dst[x][y][i] PARAMETERS
The function takes the following arguments: src2dst Pointer to second source and destination image. src1 Pointer to first source image. RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE. ATTRIBUTES

NAME
mlib_ImageBlend2_Inp - blend with an alpha image, in place SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_ImageBlend2_Inp(mlib_image *src2dst, const mlib_image *src1, const mlib_image *alpha); DESCRIPTION
The mlib_ImageBlend2_Inp() function blends two images together, in place, on a pixel-by-pixel basis using an alpha image, when alpha is also on a pixel basis. The alpha image can be a single-channel image or have the same number of channels as the source and destination images. It uses the following equation when the alpha image is a single-channel image: src2dst[x][y][i] = a[x][y][0]*src1[x][y][i] + (1 - a[x][y][0])*src2dst[x][y][i] It uses the following equation when the alpha image has the same number of channels as the source and destination images: src2dst[x][y][i] = a[x][y][i]*src1[x][y][i] + (1 - a[x][y][i])*src2dst[x][y][i] PARAMETERS
The function takes the following arguments: src2dst Pointer to second source and destination image. src1 Pointer to first source image. alpha Alpha image used to control blending. The a value equals (alpha * 2**(-8)) for MLIB_BYTE image, (alpha * 2**(-15)) for MLIB_SHORT image, (alpha * 2**(-16)) for MLIB_USHORT image, and (alpha * 2**(-31)) for MLIB_INT image. RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE. ATTRIBUTES
