mlib_ImageScalarBlend_Fp(3MLIB) mediaLib Library Functions mlib_ImageScalarBlend_Fp(3MLIB) NAME
mlib_ImageScalarBlend_Fp - image blending with scalar SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_ImageScalarBlend_Fp(mlib_image *dst, const mlib_image *src1, const mlib_image *src2, const mlib_d64 *alpha); DESCRIPTION
The mlib_ImageScalarBlend_Fp() function blends the first and second floating-point 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 which should be in the [0.0, 1.0] range. 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_ImageBlend1_Inp(3MLIB) mediaLib Library Functions mlib_ImageBlend1_Inp(3MLIB) NAME
mlib_ImageBlend1_Inp - blend with an alpha image, in place SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_ImageBlend1_Inp(mlib_image *src1dst, const mlib_image *src2, const mlib_image *alpha); DESCRIPTION
The mlib_ImageBlend1_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: src1dst[x][y][i] = a[x][y][0]*src1dst[x][y][i] + (1 - a[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: src1dst[x][y][i] = a[x][y][i]*src1dst[x][y][i] + (1 - a[x][y][i])*src2[x][y][i] PARAMETERS
The function takes the following arguments: src1dst Pointer to first source and destination image. src2 Pointer to second 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
