draw in render result is posible?

hi, how are you??

I want to know if draw (lines, circles …etc) in the render result is posible… I test with grease pencil but that don’t work because I can’t save the lines or convert that

some ideas??

thanks

Diego

pd. I don’t want use openGL render

Gimp or ms paint. But sorry I don’t think blender has simple tools in uv image editor yet.
