Özel durumlar

Örnekler

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

• Kırmızı ve yeşil kalemler oluşturur.

• Eğriyi tanımlamak için yedi nokta oluşturur.

• Bir çokgen oluşturmak için yedi nokta arasına yedi kırmızı düz çizgi çizer.

• Gerilim ve doldurma modu ayarları oluşturur.

• Yedi nokta boyunca yeşil kapalı bir eğri çizer.

yöntemi 1,0 gerilimi kullanır ve doldurma modunu FillMode.Alternateolarak ayarlar.

Açıklamalar

Bu yöntem, dizideki her noktadan geçen kapalı bir kardinal spline çizer. Son nokta ilk noktayla eşleşmiyorsa, kapatmak için son noktadan ilk noktaya ek bir eğri kesimi eklenir.

Nokta dizisi en az dört PointF yapı içermelidir.

tension parametresi, spline'ın şeklini belirler. tension parametresinin değeri 0,0F ise, bu yöntem noktaları bağlamak için düz çizgi kesimleri çizer. Genellikle tension parametresi 1,0F'den küçük veya buna eşittir. 1,0F üzerindeki değerler olağan dışı sonuçlar üretir.
