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. ATTRIBUTES
