DESCRIPTION

This routine draws a contour onto an image which is specified by the point pairs in the matrix argument. The routine image_draw_segment() is used to draw lines between consecutive points. The matrix (x,y) is mapped into image (i,j).

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.
