mlib_ImageCopyArea(3MLIB) mediaLib Library Functions mlib_ImageCopyArea(3MLIB) NAME
mlib_ImageCopyArea - copy an area SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_ImageCopyArea(mlib_image *img, mlib_s32 x, mlib_s32 y, mlib_s32 w, mlib_s32 h, mlib_s32 dx, mlib_s32 dy); DESCRIPTION
The mlib_ImageCopyArea() function copies a specified rectangular area from one portion of the image to another portion of the same image. The data type of the image can be MLIB_BIT, MLIB_BYTE, MLIB_SHORT, MLIB_USHORT, MLIB_INT, MLIB_FLOAT, or MLIB_DOUBLE. It uses the following equation: img[x+dx+i][y+dy+j][i] = img[x+i][y+j][i] where i = 0, 1, ..., w-1; j = 0, 1, ..., h-1. PARAMETERS
The function takes the following arguments: img Pointer to source image. x X coordinate of the area origin in the source. y Y coordinate of the area origin in the source. w Width of the area to be copied. h Height of the area to be copied. dx Horizontal displacement in pixels of the area to be copied. dy Vertical displacement in pixels of the area to be copied. RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE. ATTRIBUTES

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. ATTRIBUTES
