int image_draw_image
(
	KJB_image *canvas_ip,
	const KJB_image *ip,
	int i,
	int j,
	int scale
);

DESCRIPTION

This routine draws an image ip onto canvas_ip at location (i, j), reducing the size of ip by scale. The image is clipped if part (or all) of it lies outsize canvas_ip.

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.
