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

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
