To overlay a 2D line over a 2D image and (as you said later in this 
thread) not wanting shadows suggests you have the wrong tool for the 
job. POV-Ray is a 3D rendering software, and not really suitable for 2D 
image composition. The best way to manipulate 2D images in a 
programmatic way is probably ImageMagick, which is open source and 
freely available at https://imagemagick.org/
