NAME
mlib_ImageThresh3_Fp - image thresholding SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_ImageThresh3_Fp(mlib_image *dst, const mlib_image *src, const mlib_d64 *thresh, const mlib_d64 *ghigh); DESCRIPTION
The mlib_ImageThresh3_Fp() function compares each pixel in the floating-point 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 value of the source pixel. If the pixel is greater than the threshold value, then the destination pixel is set to the high output level. It uses the following equation: dst[x][y][i] = src[x][y][i] if src[x][y][i] <= thresh[i] dst[x][y][i] = ghigh[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. ghigh High output level. ghigh[i] contains the high output level for channel i. RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE. ATTRIBUTES

NAME
mlib_ImageThresh1_Fp - image thresholding SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_ImageThresh1_Fp(mlib_image *dst, const mlib_image *src, const mlib_d64 *thresh, const mlib_d64 *ghigh, const mlib_d64 *glow); DESCRIPTION
The mlib_ImageThresh1_Fp() function compares each pixel in the floating-point 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 destination pixel is set to the high output level. The data type of the destination image can be MLIB_BIT or can be the same as the data type of the source image. It uses the following equation: dst[x][y][i] = glow[i] if src[x][y][i] <= thresh[i] dst[x][y][i] = ghigh[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. ghigh High output level. ghigh[i] contains the high output level 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
