C ++ DEMASIADO GRANDE
Intenté esto usando mi biblioteca de dibujo PPM hecha en casa . Es técnicamente escalable, pero estoy limitado por mi función de relleno recursivo porque no es confiable y le gusta segmentar, creo que está usando demasiada memoria, por lo que no dejaré que el usuario configure la escala. La imagen es irregular porque las coordenadas que ingresé para cada esquina de las barras están ligeramente apagadas.
Lo configuré para comenzar con un fondo negro, luego puse un círculo blanco en el medio, luego círculos rojos y azules en eso. Se usaron rellenos recursivos para agregar el resto de rojo y azul. Luego dibujó rectángulos con líneas blancas para marcar las barras negras. Divida el fondo negro en 4 secciones con líneas blancas y use 4 rellenos recursivos para hacer que cada sección sea blanca. Hacerlo en 1 pasada habría causado una falla predeterminada. Todavía es muy lento para renderizar.
Código principal sin golf (el resto de la biblioteca es demasiado grande, jugar al golf no importa)
