int image_draw_point_2
(
	KJB_image *ip,
	int i,
	int j,
	int width,
	float f_r,
	float f_g,
	float f_b
);

DESCRIPTION

This routine sets the pixels (i += width, j += width) of "ip" to (r,g,b) in floating point. See image_draw_point() for a similar routine with integral colors. If the image uses alpha, the alpha channel is set to 255.

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.
