image_draw_point - Draws a point on an image

int image_draw_point
(
KJB_image *ip,
int i,
int j,
int width,
int r,
int g,
int b
);
DESCRIPTION
This routine sets the pixels (i += width, j += width) of "ip" to (r,g,b). The
color triple is specified using integers. See image_draw_point_2() for a
similar routine using floating point (r,g,b).
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.
