This is not a FoxPro question but someone may know the answer.

A old friend of mine developed a CAD package in Fortran years ago. He would like to migrate it to the Windows environment while maintaining it in Fortran.

He needs lightweight line-drawing functions and I thought about the Beziers screen saver that draws and erases the colored loops on the screen.

Does anyone know what API calls it uses?

The general question would be: what are the best API calls for 2D line drawing?

I believe he will be using Intel Fortran 90.
