NAME

xil_and, xil_and_const − bitwise logical AND operations

SYNOPSIS

#include <xil/xil.h>

void xil_and (XilImage src1,

XilImage src2,
XilImage dst);

void xil_and_const (XilImage src1,

unsigned int ∗constants,
XilImage dst);

DESCRIPTION

xil_and () performs a bitwise logical AND operation on each pixel of the src2 (source) image with the src1 and stores the results in the dst (destination) image. 

xil_and_const () performs a bitwise logical AND operation on each pixel of the src1 (source) image with the constants values and stores the results in the dst (destination) image.  For an n-band image, n unsigned integers must be provided, one per band. 

ERRORS

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

EXAMPLES

Bitwise logical AND image2 and image1 and store the result in dst :

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

Bitwise logical AND 4-band image1 and 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_and_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. Logical operations (AND, OR, XOR, NOT, and so on) are not supported for XIL_FLOAT data type.
