I recalled that MLCad has a mosaic generator that can take a bitmap image as input. But I haven't found a good tool to draw the circles.

1. Paint.NET output isn't symmetrical in my tests.
2. GIMP draws the circles too thick. I want them only 1px thick.
3. This tool is pretty good, but I don't know how to get rid of the gray lines. https://donatstudios.com/PixelCircleGenerator
4. Ditto. http://www.mineconics.net/

I have a copy of Paint Shop Pro somewhere. I will need to dig it out of storage.

I ended up using GeoGebra to create an exact sketch of what I want, then reproducing the sketch in POVray and rendering at a small scale and without antialiasing. For instance, I've attached an (enlarged 10x) curvy road image to this post.

Eventually I would like to write a script that generates custom unofficial road models that follow splines and other shapes. (I did this for POV-Ray already, but details like road stripes are harder to pull off in LDraw.)

It seems MLCad's mosaic generator is not converting my image exactly. There are missing bricks, and extra bricks where there shouldn't be any. I need to find a different program. Sad
