Örnekler

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

• Yeni bir LinearGradientBrusholuşturur.

• Bu fırçayı kullanarak ekrana üç nokta çizer.

• LinearGradientBrushdönüştürmek için MultiplyTransform yöntemini çağırır.

• Dönüştürülmüş fırçayı kullanarak ilk üç noktanın hemen altına bir üç nokta çizer.

• Dönüşümü sıfırlar.

• İlk ikisinin altındaki ekrana üçüncü bir üç nokta çizer.

En düşük üç noktanın ilk ile aynı boyutta çizildiğine ve ResetTransform yöntemine yapılan çağrı nedeniyle gradyanın eşleşecek şekilde küçültüldüğüne dikkat edin.
