NAME
vrast - provides routines to perform bilinear interpolated raster fills

DESCRIPTION
vrast library provides routines used to perform bilinear interpolated raster fills over areas in an image defined by four points, including degenerate cases such as colinear points, twists, etc.

For an explanation of all the following routines in greater detail, with explanations of all arguments to each routine, see the section on vrast in the Khoros Programmer's Manual, chapter 8, Libraries.

ALL programs that utilize these routines MUST include the statement:

#include "vinclude.h"
#include "vipl/lvrast.h"

AVAILABLE ROUTINES
