Parametreler
Örnekler
Aşağıdaki kod örneği, Windows Forms ile kullanılmak üzere tasarlanmıştır ve Paint bir olay nesnesi PaintEventArgse
gerektirir. Kod aşağıdaki eylemleri gerçekleştirir:
Dikdörtgen oluşturan bir nokta dizisi oluşturur.
Ölçeklendirme dönüşümü (mavi dikdörtgen) uygulamadan önce bu nokta dizisini ekrana çizer.
Bir matris oluşturur ve x ekseninde 3, y ekseninde 2 ölçeklendirir ve her iki eksende de 100'e çevirir.
Matris öğelerini ekrana listeler.
Bu matris dönüşümünü nokta dizisine uygular.
Dönüştürülen diziyi ekrana (kırmızı dikdörtgen) çizer.
Kırmızı dikdörtgenin x ekseninde 3, y ekseninde ise 2 kat ölçeklendirildiğini, dikdörtgenin sol üst köşesi (dikdörtgenin başlangıç noktası) dahil olduğuna ancak çeviri vektörünün (matrisin son iki öğesi) yoksayıldığına dikkat edin.
