NAME
mlib_ImageDivShift1_Inp - division with shifting, in place SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_ImageDivShift1_Inp(mlib_image *src1dst, const mlib_image *src2, mlib_s32 shift); DESCRIPTION
The mlib_ImageDivShift1_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: src1dst[x][y][i] = src1dst[x][y][i] / src2[x][y][i] * 2**shift In the case of src2[x][y][i] = 0, src1dst[x][y][i] = 0 if src1dst[x][y][i] = 0 src1dst[x][y][i] = DATA_TYPE_MAX if src1dst[x][y][i] > 0 src1dst[x][y][i] = DATA_TYPE_MIN if src1dst[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: src1dst Pointer to first source and destination image. src2 Pointer to second source image. shift Left shifting factor. 0 <= shift <= 31. RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE. ATTRIBUTES

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
