Re: pixel coordinates of a line

Thanks to everybody.

Tom's method of course would work,
but I don't like to do such things in IDL 'by hand'.
Even in my case now, speed is not a matter.

Alex method with the polygon was really interesting.
Even I am not sure about the clipping here.
But I ended up using the z buffer method.

The interpolate routine is also a good suggestion, 
but also doesn't consider the clipping.

Anyway,
some useful tips for further problems,
thanks again,
:-) marc
