mlib_ImageCopyMask(3MLIB) mediaLib Library Functions mlib_ImageCopyMask(3MLIB) NAME
mlib_ImageCopyMask - copy with mask SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_ImageCopyMask(mlib_image *dst, const mlib_image *src, const mlib_image *mask, const mlib_s32 *thresh); DESCRIPTION
The mlib_ImageCopyMask() function copies one image to another image via a mask image by using it as a yes/no indicator. The data type of the images can be MLIB_BYTE, MLIB_SHORT, MLIB_USHORT, or MLIB_INT. It uses the following equation: dst[x][y][i] = src[x][y][i] if mask[x][y][i] <= thresh[i] dst[x][y][i] = dst[x][y][i] if mask[x][y][i] > thresh[i] PARAMETERS
The function takes the following arguments: dst Pointer to destination image. src Pointer to source image. mask Pointer to mask image. thresh Threshold for the mask image. thresh[i] contains the threshold for channel i. RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE. ATTRIBUTES

mlib_ImageThresh2(3MLIB) mediaLib Library Functions mlib_ImageThresh2(3MLIB) NAME
mlib_ImageThresh2 - image thresholding SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_ImageThresh2(mlib_image *dst, const mlib_image *src, const mlib_s32 *thresh, const mlib_s32 *glow); DESCRIPTION
The mlib_ImageThresh2() function compares each pixel in the source image to a threshold value. If the pixel is less than or equal to the threshold value, then the destination pixel is set to the low output level. If the pixel is greater than the threshold value, then the des- tination pixel is set to the value of the source pixel. It uses the following equation: dst[x][y][i] = glow[i] if src[x][y][i] <= thresh[i] dst[x][y][i] = src[x][y][i] if src[x][y][i] > thresh[i] PARAMETERS
The function takes the following arguments: dst Pointer to destination image. src Pointer to source image. thresh Threshold value. thresh[i] contains the threshold for channel i. glow Low output level. glow[i] contains the low output level for channel i. RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE. ATTRIBUTES
