int pixel_in_primitive ( PRIM_NODE *prim, int x, int y )

PRIM_NODE *prim;  // pointer to primitive

int        x;     // x coordinate of pixel

int        y;     // y coordinate of pixel

Synopsis

#include "silver.h"

The pixel_in_primitive function function examines primitive prim to determine if the pixel a location x, y lies within the boundaries of the primitive.

Parameters

prim is a pointer to a primitive. x and y are pixel coordinates, with 0 <= x < spixel_width and 0 <= y < spixel_height .

Return Value

If the pixel lies within the boundary of the primitive, 1 is returned.  Otherwise 0 is returned.
