Große Herausforderung. Hier ist meine Lösung. Ich habe versucht, dem ursprünglichen Comic so nahe wie möglich zu kommen, ich habe sogar die xkcd-Schriftart verwendet .
Es ist eine WPF-Anwendung, aber ich System.Drawinghabe die Zeichnungsteile gemacht, weil ich faul bin.
Grundkonzept: In WPF sind Fenster Visuals, dh sie können gerendert werden. Ich rendere die gesamte Window-Instanz auf eine Bitmap, zähle das Schwarz und das gesamte Schwarz oder Weiß auf (ohne die Graustufen in der Schriftglättung und so weiter) und zähle diese auch für jedes Drittel des Bildes auf (für jedes Panel). Dann mache ich es nochmal auf einem Timer. Es erreicht das Gleichgewicht innerhalb von ein oder zwei Sekunden.

Überprüfen Sie heruntergeladene Dateien immer auf Viren usw.
Sie müssen die oben genannte Schriftart auf Ihrem System installieren, wenn Sie sie sehen möchten. Andernfalls ist sie die Standard-WPF-Schriftart.

Der Code ist nicht aufgeräumt, sollte aber etwas lesbar sein, sorry.
