Ptolemy Art Encoder

Type a message and the image updates in real time. This page performs two checks: it decodes from the generated SVG geometry and again from a simulated PNG rendered to a hidden canvas. It also renders a visible raster debug overlay showing how each character was recovered.

Message

Recovered parameters

Red = logical start anchor Green = logical unit marker Magenta = character separators Cyan overlay = recovered AC chord Red overlay = recovered BD chord

Encoding per character: ASCII = 16q + r, AB = q + 1, BC = r + 1, CD = 1. The visible layout uses v = m·k mod N to spread the chords through the circle.
