C ++ TROPPO GRANDE
Ho tentato di farlo usando la mia libreria di disegni PPM fatta in casa . È tecnicamente scalabile, ma sono limitato dalla mia funzione di riempimento ricorsivo perché è inaffidabile e gli piace segfault, penso che stia usando troppa memoria, quindi non permetterò all'utente di impostare la scala. L'immagine è irregolare perché le coordinate che ho inserito per ogni angolo delle barre sono leggermente spente.
L'ho impostato per iniziare con uno sfondo nero, quindi ho inserito un cerchio bianco nel mezzo, quindi cerchi rossi e blu. Riempimenti ricorsivi usati per aggiungere il resto di rosso e blu. Quindi disegna rettangoli con linee bianche per contrassegnare le barre nere. Dividi lo sfondo nero in 4 sezioni con linee bianche e usa 4 riempimenti ricorsivi per rendere bianca ogni sezione. Farlo in 1 passaggio avrebbe causato un segfault. Il rendering è ancora molto lento.
Codice principale non golfato (il resto della biblioteca è troppo grande, il golf non ha importanza)
