Circle/curve generator?

[Michael Horvath]

Is there a tool available that can draw a curve or circle with a given radius, and then approximate that curve with bricks? Thanks.

[edit]

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.

If all you want is a paint program that can draw symmetrical bitmap curves, you can use MS Paint. Hold down Shift while drawing an oval to get a circle, and unlike Paint.NET, MS Paint draws symmetrical circles (as far as I can tell). Blow up the resulting image if you need to (without any smoothing) to make it pixellated. Do your actual drawing at 400%-800% zoom to better see what you're doing. (Note that I'm using MS Paint in Windows 10 with Anniversary update, but I think it has behaved this way pretty much forever.)

Thanks! I was able to create the attached image in case someone needs it. It is scaled up 10x for clarity. Normally, it is 32x32px which is the same size as a baseplate according to MLCad's mosaic generator.
