Örnekler

Aşağıdaki kod örneği, görüntüyü yeniden renklendirmek için ve SetPixel yöntemlerini kullanarak GetPixel bir dosyadan yeni Bitmap oluşturma işlemini gösterir. Ayrıca , Widthve Height özelliklerini kullanırPixelFormat.

Bu örnek sırasıyla ,PictureBox ve Button adlı Label1PictureBox1Button1ve içeren bir Label Windows Forms ile kullanılmak üzere tasarlanmıştır. Kodu forma yapıştırın ve yöntemini düğmenin Click olayıyla ilişkilendirinButton1_Click.
