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 = new Bitmap("Grapes.jpg"); // Get the color of a pixel within myBitmap. Color pixelColor = myBitmap.GetPixel(50, 50); // Fill a rectangle with pixelColor. SolidBrush pixelBrush = new SolidBrush(pixelColor); e.Graphics.FillRectangle(pixelBrush, 0, 0, 100, 100); }
