參數
範例
下列程式代碼範例是專為搭配 Windows Forms 使用而設計,而且需要 PaintEventArgse
,這是 Paint 事件處理程式的參數。 程式代碼會執行下列動作:
建立左上角為 (0, 0) 的矩形,並將裁剪區域設定為此矩形。
建立左上角為 (100, 100) 的第二個矩形,並將裁剪區域設定為此矩形的交集和目前的裁剪區域(第一個矩形)。
以純藍色筆刷填滿包含上述兩個矩形的大型矩形。
將裁剪區域重設為無限。
在兩個裁剪區域周圍繪製矩形。 它會針對第一個裁剪矩形使用黑色畫筆,第二個裁剪區域的紅色畫筆。
結果是只有兩個矩形的交集填滿藍色。
public:
void IntersectClipRectangle( PaintEventArgs^ e )
{
// Set clipping region.
Rectangle clipRect = Rectangle(0,0,200,200);
e->Graphics->SetClip( clipRect );
// Update clipping region to intersection of
// existing region with specified rectangle.
Rectangle intersectRect = Rectangle(100,100,200,200);
e->Graphics->IntersectClip( intersectRect );
// Fill rectangle to demonstrate effective clipping region.
e->Graphics->FillRectangle( gcnew SolidBrush( Color::Blue ), 0, 0, 500, 500 );
// Reset clipping region to infinite.
e->Graphics->ResetClip();
// Draw clipRect and intersectRect to screen.
e->Graphics->DrawRectangle( gcnew Pen( Color::Black ), clipRect );
e->Graphics->DrawRectangle( gcnew Pen( Color::Red ), intersectRect );
}
private void IntersectClipRectangle(PaintEventArgs e)
{
// Set clipping region.

// Reset clipping region to infinite.

// Draw clipRect and intersectRect to screen.
e.Graphics.DrawRectangle(new Pen(Color.Black), clipRect);
e.Graphics.DrawRectangle(new Pen(Color.Red), intersectRect);
