NAME

xil_lookup_get_band_lookup − get a single lookup table out of a combined lookup

SYNOPSIS

#include <xil/xil.h>

XilLookup xil_lookup_get_band_lookup ( XilLookup lookup,

unsigned int band_num)

DESCRIPTION

This function creates a copy of the lookup for the specified band in a combined lookup table. lookup is the handle to the combined lookup table, and band_num is the band number to be copied.

The lookup table that is returned is a single lookup table with one output element per input value. It can be used to convert a single-band input image to another single-band input image, or it can be used as the lookup table for one band of a multiband input image. It cannot be used to convert single-band data to multiband data.
