範例

以下程式碼範例是為 Windows Forms 設計，並需要 PaintEventArgse，一個 OnPaint 事件物件。 此程式碼會執行下列動作：

• 建立圖形路徑並加入一個矩形。

• 從路徑點（在此例中，點形成矩形，但幾乎可以是任何形狀）建立 a PathGradientBrush 。

• 將中心顏色設為紅色，周圍顏色設為藍色。

• 在應用乘法轉換前，先 PathGradientBrush 將 畫到 螢幕上。

• 建立 s 矩陣，將畫筆旋轉 90 度，並在兩個軸向平移 100 度。

• 將此矩陣應用於畫筆上，方法是使用該 MultiplyTransform 方法。

• 把畫筆拉到螢幕上。
