mediaLib Library Functions mlibImageConstDivInp(3MLIB)
NAME
mlibImageConstDivInp - division into a constant
SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include
mlibstatus mlibImageConstDivInp(mlibimage *srcdst, const mlibd64 *c);
DESCRIPTION
The mlibImageConstDivInp() function divides each pixel in
an image by a constant value on a pixel-by-pixel basis, in
place.
It uses the following equation:
srcdst[x][y][i] = c[i] / srcdst[x][y][i]
In the case of srcdst[x][y][i] = 0,
srcdst[x][y][i] = 0 if c[i] = 0
srcdst[x][y][i] = DATATYPEMAX if c[i] > 0
srcdst[x][y][i] = DATATYPEMIN if c[i] < 0
where DATATYPE is MLIBU8, MLIBS16, MLIBU16, or MLIBS32
for an image of type MLIBYTE, MLIBSHORT, MLIBUSHORT, or
MLIBINT, respectively.
PARAMETERS
The function takes the following arguments:
srcdst Pointer to source and destination image.
c Constant into which each pixel is divided. c[i]
contains the constant for channel i.
RETURN VALUES
The function returns MLIBSUCES if successful. Otherwise
it returns MLIBFAILURE.
