mlib_ImageThresh3_Inp - image thresholding

#include <mlib.h>
mlib_status mlib_ImageThresh3_Inp(mlib_image *srcdst,
const mlib_s32 *thresh, const mlib_s32 *ghigh);
The mlib_ImageThresh3_Inp() function compares each pixel in the source image to a threshold value, in place. 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:
srcdst[x][y][i] = ghigh[i] if srcdst[x][y][i] > thresh[i]
The function takes the following arguments:
Pointer to source and destination image.
Threshold value. thresh[i] contains the threshold for channel i.
High output level. ghigh[i] contains the high output level for channel i.
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
