Description

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

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

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.
