NAME

xil_xor, xil_xor_const − bitwise logical XOR operations

SYNOPSIS

#include <xil/xil.h>

void xil_xor (XilImage src1,

XilImage src2,
XilImage dst);

void xil_xor_const (XilImage src1,

unsigned int ∗constants,
XilImage dst);

DESCRIPTION

xil_xor () performs a bitwise logical XOR operation on each pixel of the src2 (source) image with the src1 image and stores the result in the dst (destination) image. 

xil_xor_const () performs a bitwise logical XOR operation on each pixel of the src1 (source) image with a specified constant and stores the results in the dst (destination) image.  For a n-band image, n unsigned integers must be provided, one per band.  The value of constants[0] is XORed with the values in band 0, and so on. 

ERRORS

For a complete list of XIL error messages by number, consult Appendix B of the XIL Programmer’s Guide. 

EXAMPLES

Bitwise logical XOR image2 with image1 and store the result in dst:

XilImage image1, image2, dst;
xil_xor(image1, image2, dst);

Bitwise logical XOR a 4-band image1 with 4 constants and store the result in dst:

XilImage image, dst;
unsigned int constants[4];
constants[0] = 1;
constants[1] = 0;
constants[2] = 0;
constants[3] = 0;
xil_xor_const(image, constants, dst);

NOTES

Source and destination images must be the same data type and have the same number of bands.  In-place operations are supported.
