mlib_ImageScalarBlend(3MLIB) mediaLib Library Functions mlib_ImageScalarBlend(3MLIB) NAME
mlib_ImageScalarBlend - image blending with scalar SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_ImageScalarBlend(mlib_image dst, const mlib_image *src1, const mlib_image *src2, const mlib_s32 *alpha); DESCRIPTION
The mlib_ImageScalarBlend() function blends the first and second source images by adding each of their scaled pixels. The first source image is scaled by the scalar a, and the second source image is inverse scaled by (1 - a). It uses the following equation: dst[x][y][i] = a[i]*src1[x][y][i] + (1 - a[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 Scalar blending factor. The a value equals (alpha * 2**(-31)). alpha[i] contains the blending factor for channel i. RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE. ATTRIBUTES

mlib_ImageBlend2_Fp_Inp(3MLIB) mediaLib Library Functions mlib_ImageBlend2_Fp_Inp(3MLIB) NAME
mlib_ImageBlend2_Fp_Inp - blend with an alpha image SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_ImageBlend2_Fp_Inp(mlib_image *src2dst, const mlib_image *src1, const mlib_image *alpha); DESCRIPTION
The mlib_ImageBlend2_Fp_Inp() function blends two images together, in place, on a pixel-by-pixel basis using an alpha image, when a 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] = alpha[x][y][0]*src1[x][y][i] + (1 - alpha[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] = alpha[x][y][i]*src1[x][y][i] + (1 - alpha[x][y][i])*src2dst[x][y][i] It uses the following equation: 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 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
