The following code example is designed for use with Windows Forms, and it requires PaintEventArgse, which is a parameter of the Paint event handler. The code gets the color of a pixel in a bitmap, and then fills a rectangle with that color.
private: void GetPixel_Example( PaintEventArgs^ e ) { // Create a Bitmap object from an image file. Bitmap^ myBitmap = gcnew Bitmap( "Grapes.jpg" ); // Get the color of a pixel within myBitmap. Color pixelColor = myBitmap->GetPixel( 50, 50 ); // Fill a rectangle with pixelColor. SolidBrush^ pixelBrush = gcnew SolidBrush( pixelColor ); e->Graphics->FillRectangle( pixelBrush, 0, 0, 100, 100 ); }
