예제

다음 코드 예제는 Windows Forms에서 사용하도록 설계되었으며 Paint 이벤트 처리기의 매개 변수인 PaintEventArgse필요합니다. 코드 예제에서는 한 RegionData 개체의 Data 사용하여 다른 RegionData대한 Data 설정하는 방법을 보여 줍니다.

   void DemonstrateRegionData2( PaintEventArgs^ e )
   {
      //Create a simple region.
      System::Drawing::Region^ region1 = gcnew System::Drawing::Region( Rectangle(10,10,100,100) );

      // Extract the region data.
      System::Drawing::Drawing2D::RegionData^ region1Data = region1->GetRegionData();
      array<Byte>^data1;
      data1 = region1Data->Data;

      System::Drawing::Region^ region2 = gcnew System::Drawing::Region;

설명

Region 클래스를 사용하면 사용자 지정 셰이프를 정의할 수 있습니다. 셰이프는 선, 다각형 및 곡선으로 구성될 수 있습니다. GetRegionData 이 Region포함된 셰이프를 설명합니다.
