mlib_ImageDivShift2_Inp(3MLIB) mediaLib Library Functions mlib_ImageDivShift2_Inp(3MLIB) NAME
mlib_ImageDivShift2_Inp - division with shifting, in place SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_ImageDivShift2_Inp(mlib_image *src2dst, const mlib_image *src1, mlib_s32 shift); DESCRIPTION
The mlib_ImageDivShift2_Inp() function divides the second source image into the first source image on a pixel-by-pixel basis. It scales the result by a left shift and writes the result to the destination image on a pixel-by-pixel basis. It uses the following equation: src2dst[x][y][i] = src1[x][y][i] / src2dst[x][y][i] * 2**shift In the case of src2dst[x][y][i] = 0, src2dst[x][y][i] = 0 if src1[x][y][i] = 0 src2dst[x][y][i] = DATA_TYPE_MAX if src1[x][y][i] > 0 src2dst[x][y][i] = DATA_TYPE_MIN if src1[x][y][i] < 0 where DATA_TYPE is MLIB_U8, MLIB_S16, MLIB_U16, or MLIB_S32 for an image of type MLIB_BYTE, MLIB_SHORT, MLIB_USHORT, or MLIB_INT, respec- tively. PARAMETERS
The function takes the following arguments: src2dst Pointer to second source and destination image. src1 Pointer to first source image. shift Left shifting factor. 0 <= shift <= 31. 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
