The following code example demonstrates how to construct a bitmap from a type, and how to use the Save method. To run this example, paste the code into a Windows Form. Handle the form’s Paint event, and call the ConstructFromResourceSaveAsGif method, passing e as PaintEventArgs
private: void ConstructFromResourceSaveAsGif(PaintEventArgs^ e) { // Construct a bitmap from the button image resource. Bitmap^ bmp1 = gcnew Bitmap(Button::typeid, "Button.bmp"); String^ savePath = Environment::GetEnvironmentVariable("TEMP") + "\\Button.bmp"; try { // Save the image as a GIF. bmp1->Save(savePath, System::Drawing::Imaging::ImageFormat::Gif); } catch (IOException^) { // Carry on regardless } // Construct a new image from the GIF file. Bitmap^ bmp2 = nullptr; if (File::Exists(savePath)) { bmp2 = gcnew Bitmap(savePath); } // Draw the two images. e->Graphics->DrawImage(bmp1, Point(10, 10)); // If bmp1 did not save to disk, bmp2 may be null if (bmp2 != nullptr) { e->Graphics->DrawImage(bmp2, Point(10, 40)); } // Dispose of the image files. delete bmp1; if (bmp2 != nullptr) { delete bmp2; } }
private void ConstructFromResourceSaveAsGif(PaintEventArgs e)
{
// Construct a bitmap from the button image resource.
Bitmap bmp1 = new Bitmap(Button.class.ToType(), "Button.bmp");
// Save the image as a GIF.
bmp1.Save("c:\\button.gif", System.Drawing.Imaging.ImageFormat.get_Gif());
// Construct a new image from the GIF file.
Bitmap bmp2 = new Bitmap("c:\\button.gif");
// Draw the two images.
e.get_Graphics().DrawImage(bmp1, new Point(10, 10));
e.get_Graphics().DrawImage(bmp2, new Point(10, 40));
// Dispose of the image files.
bmp1.Dispose();
bmp2.Dispose();
} //ConstructFromResourceSaveAsGif
