Büyük zorluk. İşte benim çözümüm. Orijinal çizgi romana olabildiğince yaklaşmaya çalıştım, hatta xkcd fontunu bile kullandım .
Bu bir WPF uygulaması, ancak System.Drawingtembel olduğum için çizim parçalarını kullanırdım.
Temel kavram: WPF'de pencereler Visuals, yani oluşturulabilecekleri anlamına gelir. Tüm Window örneğini bir bitmap üzerinde oluşturuyorum, siyah ve toplam siyah veya beyazı sayıyorum (yazı tipi yumuşatması ve öğelerinde grileri yok sayarak) ve ayrıca görüntünün her 3'ünde de (her panel için) sayıyorum. Sonra tekrar bir zamanlayıcıda yapıyorum. Bir veya iki saniye içinde dengeye ulaşır.

Her zaman indirdiğiniz dosyaları virüs, vb. İçin kontrol edin.
Görmek istiyorsanız yukarıdaki yazı tipini sisteminize yüklemeniz gerekir, aksi takdirde WPF varsayılanıdır.

Kod temizlenmedi, ancak biraz okunabilir olmalı, üzgünüm.
