image_draw_gradient - Draws a line segment with gradient on an image

SYNOPSIS

#include "i/i_draw.h"

int image_draw_gradient
(
	KJB_image *ip,
	Vector *p1_vp,
	Vector *p2_vp,
	int width,
	int r1,
	int g1,
	int b1,
	int r2,
	int g2,
	int b2
);

DESCRIPTION

This routine sets the pixels of "ip" in the segment joining p1_vp and p2_vp to a shade of (r1,g1,b1) and (r2,g2,b2).

NOTE

If displayed, image (i,j) generally results in the first coordinate indexing row number downwards, and the second coordinate indexing column. Thus the X and Y axes swap, and the vertical axis goes in the opposite direction than in the XY coordinate system.

DISCLAIMER

This software is not adequatedly tested. It is recomended that results are checked independantly where appropriate.
