A bit of a lot of things – lots of trial and error. But I settled on a process for now: Paint dot NET is my homebase. a) Have color image. b) Convert it to 1-bit using a little thing I found http://blog.roguecode.co.za/update-for-my-agent-1-bit-image-converter-1bitter/ c) Open in Inkscape d) Control-A (Select All) e)Path:Trace Bitmap “Grays” Turn off Smooth Options: Turn off Smooth Corners f) Path: Simplify (or Control-L) about three times g) File: Export Bitmap. To do: 1) Automate b) – maybe imagemagick “convert” can do it? 2) Maybe shrinking the image to like 64×64 will make thresholding work better? I don’t know. 3) Use potrace instead of Inkscape for tracing. I did and can but as I haven’t mastered potrace at all, I have to learn its options (same problem I have with Imagemagick – I don’t know it well) 4) Find another way to “simplify”. I think potrace can but I don’t know for sure.

It was the help of an app called Fourier Anime that got me started. It created rubber-band animation from a standard image. I took one of the frames, simplified it further using Inkscape’s “simplify” to get here. App page for Fourier Anime says it uses this process, which I’d like to figure out to do by hand: 1. Edge Detect Differentiate the luminosity value of the monochrome input image, then we can get the edges where the luminosity are changing significantly. 2. Find Contours Extract contour curves from the edge image one by one. 3. Fourier Transform Contours are the sequences of points. Convert this complex sequences into Fourier coefficients by Fourier transform. 4. Low-pass Filter Leave only the coefficients of low-frequency parts. 5. Inverse Fourier Transform Reconstruct the complex sequences of points from low-pass filtered Fourier coefficients. And draw the curves in the display (parametric representation).

I voted for Gillum as well. Community oriented guy as Mayor. It’s good for all of Florida, including Republicans who just don’t realize that yet.

His parents were Methodist and to raise him as a normal boy, he’d have been baptised Methodist. Since didn’t convert to anything else, Superman is still Methodist.

I’m looking forward to whoever gets in next. Exploring EVERY loophole of “It doesn’t say I “CAN’T” do this” will cause ALL THOSE LOOPHOLES his lawyers are finding for him to get closed. More rules for whoever comes after to PREVENT this from happening again. Obama was our last President. Whoever is our next President won’t get the same luxuries as whoever’s sitting there now.
