Bu Colordoygunluğu. Doygunluk 0,0 ile 1,0 arasında değişir ve burada 0,0 gri tonlamalı ve 1,0 en doygundur.

Örnekler

Aşağıdaki kod örneği Windows Forms ile kullanılmak üzere tasarlanmıştır ve Paint olay işleyicisinin bir parametresi olan PaintEventArgsegerektirir. Kod aşağıdaki eylemleri gerçekleştirir:

• Karşılaştırmalar için kullanılacak Color yapısının redShadebir örneğini oluşturur.

• redShadeile aynı doygunluğa sahip tüm bilinen renkleri bulmak için KnownColor numaralandırma öğelerinde yinelenir. 15 eşleşme bulunduğunda veya döngü sayacının değeri son KnownColor öğesinden büyük olduğunda yinelemeler sonlandırılır.

• Her yineleme sırasında, KnownColor öğesini (ölçütlerle eşleşiyorsa) bir diziye kaydeder.

• Dikdörtgenleri boyamak için fırça kullanır.

İlk dikdörtgen, redShadeile temsil edilen renge boyanmış. Diğer dikdörtgenlerin her biri, redShadedoygunluğuyla eşleşen bir KnownColor boyanmış.
