emptypoly Empty the polygons contained in a cimage
emptypoly cimage_polys cimage_empty
cimage_polys : cimage of polygons (input)
cimage_empty : the same cimage with empty polygons (output)
Cimage emptypoly (A , B )
Cimage A , B ;
This module empties the content of polygons in a cimage, as polygon images created using the fillpolys module. As a result, we get an image of squeletons. In this sense it is an inverse transform of fillpolys, except that the output is still an image instead of a polys structure.
