xil_sel_get_height(3)

NAME

xil_sel_get_height, xil_sel_get_width, xil_sel_get_key_x, xil_sel_get_key_y − read the values of structuring element attributes

SYNOPSIS

#include <xil/xil.h>

unsigned int xil_sel_get_height ( XilSel sel);

unsigned int xil_sel_get_width ( XilSel sel);

unsigned int xil_sel_get_key_x ( XilSel sel);

unsigned int xil_sel_get_key_y ( XilSel sel);

DESCRIPTION

These routines read the values of structuring element (SEL) objects used in erosion and dilation imaging operations. Key values specify the key pixel position - a position relative to the upper left corner of the SEL. The key pixel aligns with the output pixel and constrains which input pixels are used to generate the output.

xil_sel_get_height () gets the height of the specified SEL.

xil_sel_get_width () gets the width of the specified SEL.

xil_sel_get_key_x () gets the x coordinate of the key value of the specified SEL.

xil_sel_get_key_y () gets the y coordinate of the key value of the specified SEL.

ERRORS

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

EXAMPLES

Get the coordinates of a SEL’s key value:

XilSel sel;
unsigned int key_x, key_y;
key_x = xil_sel_get_key_x (sel);
key_y = xil_sel_get_key_y (sel);
