mlib_imageextrema2_fp
mlib_ImageExtrema2(3MLIB) mediaLib Library Functions mlib_ImageExtrema2(3MLIB)
NAME
mlib_ImageExtrema2, mlib_ImageExtrema2_Fp - image extrema
SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include <mlib.h>
mlib_status mlib_ImageExtrema2(mlib_s32 *min, mlib_s32 *max,
const mlib_image *img, mlib_s32 xStart, mlib_s32 yStart,
mlib_s32 xPeriod, mlib_s32 yPeriod);
mlib_status mlib_ImageExtrema2_Fp(mlib_d64 *min, mlib_d64 *max,
const mlib_image *img, mlib_s32 xStart, mlib_s32 yStart,
mlib_s32 xPeriod, mlib_s32 yPeriod);
DESCRIPTION
Each of the functions determines the extrema values for each channel in an image, possibly with subsampling.
It uses the following equation:
min[i] = MIN{ img[x][y][i] }
max[i] = MAX{ img[x][y][i] }
where
x = xStart + p*xPeriod; 0 <= p < (w - xStart)/xPeriod
y = yStart + q*yPeriod; 0 <= q < (h - yStart)/yPeriod
PARAMETERS
Each of the functions takes the following arguments:
min Pointer to minimum vector, where length is the number of channels in the image. min[i] contains the minimum of channel i.
max Pointer to maximum vector, where length is the number of channels in the image. max[i] contains the maximum of channel i.
img Pointer to a source image.
xStart Initial X sample coordinate.
yStart Initial Y sample coordinate.
xPeriod X sample rate. xPeriod >= 1.
yPeriod Y sample rate. yPeriod >= 1.
RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
