Go to Java to get the pixel color of a picture

public int getpixel (int x,int y) throws awtexception{//function returns the RGB value of the color.
Robot RB = null; The class in the Java.awt.image package can be used to crawl the screen, that is, screenshots.
RB = new Robot ();
Toolkit tk = Toolkit.getdefaulttoolkit (); Get the default toolkit
Dimension di = Tk.getscreensize (); Screen Size Specifications
Rectangle rec = new Rectangle (0,0,di.width,di.height);
BufferedImage bi = rb.createscreencapture (rec);
int pixelcolor = Bi.getrgb (x, y);
return 16777216+pixelcolor; The value of Pixelcolor is negative, after practice: The maximum color value is the actual color value.
}
