TranslateTransform(Single, Single, MatrixOrder)

來源:

LinearGradientBrush.cs

依照指定的順序，根據指定的維度來轉換局部幾何變換。

public:
 void TranslateTransform(float dx, float dy, System::Drawing::Drawing2D::MatrixOrder order);

public void TranslateTransform (float dx, float dy, System.Drawing.Drawing2D.MatrixOrder order);

member this.TranslateTransform : single * single * System.Drawing.Drawing2D.MatrixOrder -> unit

Public Sub TranslateTransform (dx As Single, dy As Single, order As MatrixOrder)

參數

dx

Single

x 中轉譯的值。

dy

Single

y 中轉譯的值。

order

MatrixOrder

用來套用轉譯的順序 (附加在前端或後端)。

範例

下列程式代碼範例是設計來搭配 Windows Forms 使用，而且需要 PaintEventArgse事件OnPaint物件。 此程式碼會執行下列動作：

• 建立新的 LinearGradientBrush。

• 使用此筆刷將矩形繪製到具有色彩線性、由左至右轉換的螢幕。

• 旋轉 LinearGradientBrush 90 度並縮放漸層。

• 將旋轉和縮放漸層的矩形繪製到螢幕。

• 轉譯矩形，使其具有從上到下執行的線性漸層。

• 將轉譯的矩形繪製到畫面。

請注意，有三個矩形顯示上層，其中顯示由左至右的漸層、中間的矩形顯示旋轉和縮放的漸層，以及顯示最終轉譯漸層的底部。
