Get the color of a specific pixelTag(s): AWT
We assume that we have an Image called picture
    
pixels = new int[width*height];
PixelGrabber pg = 
   new PixelGrabber(picture, 0, 0, width, height, pixels, 0, width);
try { 
  pg.grabPixels(); 
}
catch (InterruptedException e)  { }int c = pixels[index]; // or pixels[x * width + y] int red = (c & 0x00ff0000) >> 16; int green = (c & 0x0000ff00) >> 8; int blue = c & 0x000000ff; // and the Java Color is ... Color color = new Color(red,green,blue);
Here another way to achieve this
import javax.imageio.ImageIO; import java.awt.image.BufferedImage ... BufferedImage image = ImageIO.read(urlImage); int c = image.getRGB(x,y); int red = (c & 0x00ff0000) >> 16; int green = (c & 0x0000ff00) >> 8; int blue = c & 0x000000ff; // and the Java Color is ... Color color = new Color(red,green,blue);
