mlib_ImageBlendRGBA2BGRA - image blending and channel reordering SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_ImageBlendRGBA2BGRA(mlib_image *dst, const mlib_image *src); DESCRIPTION
The mlib_ImageBlendRGBA2BGRA() function blends the source image of the RGBA format into the destination image of the BGRA format. The image type must be MLIB_BYTE. The source and destination images must contain four channels. It uses the following equation: Cd = Cs*As + Cd*(1 - As) Ad = Ad where, Cs and Cd are the RGB color components of the source and destination images, respectively. As and Ad are the alpha components of the source and destination images, respectively. PARAMETERS
The function takes the following arguments: dst Pointer to destination image. src Pointer to source image. RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE. ATTRIBUTES

mlib_ImageBlend_Fp(3MLIB) mediaLib Library Functions mlib_ImageBlend_Fp(3MLIB) NAME
mlib_ImageBlend_Fp - blend with an alpha image SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_ImageBlend_Fp(mlib_image *dst, const mlib_image *src1, const mlib_image *src2, const mlib_image *alpha); DESCRIPTION
The mlib_ImageBlend_Fp() function blends two images together 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: dst[x][y][i] = alpha[x][y][0]*src1[x][y][i] + (1 - alpha[x][y][0])*src2[x][y][i] It uses the following equation when the alpha image has the same number of channels as the source and destination images: dst[x][y][i] = alpha[x][y][i]*src1[x][y][i] + (1 - alpha[x][y][i])*src2[x][y][i] PARAMETERS
The function takes the following arguments: dst Pointer to destination image. src1 Pointer to first source image. src2 Pointer to second source image. alpha Alpha image used to control blending. The pixels in this image should have values in the range of [0.0, 1.0]. RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE. ATTRIBUTES
