Örnekler

Aşağıdaki kod örneği, Windows Forms ile kullanılmak üzere tasarlanmıştır ve OnPaint bir olay nesnesi PaintEventArgsegerektirir. Kod aşağıdaki eylemleri gerçekleştirir:

• Bir grafik yolu oluşturur ve buna bir dikdörtgen ekler.

• Yol noktalarından bir PathGradientBrush oluşturur (bu örnekte, noktalar bir dikdörtgen oluşturur, ancak çoğu şekil olabilir).

• Orta rengi kırmızıya, çevresindeki rengi maviye ayarlar.

• Çarpma dönüşümünü uygulamadan önce PathGradientBrush ekrana çizer.

• Fırçayı 90 derece döndüren ve her iki eksende de 100 çeviren s matrisi oluşturur.

• MultiplyTransform yöntemini kullanarak bu matrisi fırçaya uygular.

• Fırçayı ekrana çizer.
