DESCRIPTION

This routine draws a circle of radius 'radius' at location (i,j) onto an image. See image_draw_circle_2() for a version that takes floating point RGB.

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.
