#include <mlib.h>

mlib_status mlib_ImageLookUp_Inp(mlib_image *srcdst, const void **table);

Description

The mlib_ImageLookUp_Inp() function maps the source image to the destination image, in place, by using the user-specified lookup table.

The following equation is used:

srcdst[x][y][i] = table[i][srcdst[x][y][i]]

Parameters

The function takes the following arguments:

srcdst

Pointer to first source and destination image.

table

Pointer to lookup table. The data type of the lookup table is the same as the destination image. The number of entries in the lookup table is determined by the type of the input image. The format of the lookup table is:

table[channel][index]

The MLIB_BYTE type entries are indexed from 0 to 255. The MLIB_SHORT type entries are indexed from -32768 to -1, then from 0 to 32767. The MLIB_USHORT type entries are indexed from 0 to 65535. The MLIB_INT type entries are indexed from -2147483648 to -1, and then from 0 to 2147483647.

Return Values
