Contoh

Contoh kode berikut menunjukkan cara menggunakan ToBitmap metode . Contoh ini dirancang untuk digunakan dengan Formulir Windows. Buat formulir dan tempelkan kode berikut ke dalamnya. IconToBitmap Panggil metode dalam penanganan aktivitas formulirPaint, meneruskan e sebagai PaintEventArgs.

private:
   void IconToBitmap( PaintEventArgs^ e )
   {
      // Construct an Icon.
      System::Drawing::Icon^ icon1 = gcnew System::Drawing::Icon( SystemIcons::Exclamation,40,40 );

      // Call ToBitmap to convert it.
      Bitmap^ bmp = icon1->ToBitmap();

      // Draw the bitmap.
      e->Graphics->DrawImage( bmp, Point(30,30) );
   }

private void IconToBitmap(PaintEventArgs e)
{
    // Construct an Icon.
    Icon icon1 = new Icon(SystemIcons.Exclamation, 40, 40);

    // Call ToBitmap to convert it.
    Bitmap bmp = icon1.ToBitmap();

    // Draw the bitmap.
    e.Graphics.DrawImage(bmp, new Point(30, 30));
}

Private Sub IconToBitmap(ByVal e As PaintEventArgs)

    ' Construct an Icon.
    Dim icon1 As New Icon(SystemIcons.Exclamation, 40, 40)

    ' Call ToBitmap to convert it.
    Dim bmp As Bitmap = icon1.ToBitmap()

    ' Draw the bitmap.
    e.Graphics.DrawImage(bmp, New Point(30, 30))
End Sub

Keterangan

Anda dapat membuat Icon objek dari file, aliran, atau sumber daya yang disematkan. Untuk daftar konstruktor, lihat Icon. Anda juga dapat mengonversi Icon ke bitmap dengan menggunakan ToBitmap metode .

Sumber daya ikon dapat berisi beberapa gambar ikon. Satu file ikon mungkin berisi gambar dalam beberapa ukuran dan kedalaman warna. Gambar yang digunakan dalam aplikasi tergantung pada sistem operasi dan pengaturan. Daftar berikut merinci ukuran umum untuk ikon:

• 16 piksel x 16 piksel

• 32 piksel x 32 piksel

• 48 piksel x 48 piksel
