Getting the colour of where you have clicked on a JPanel?
I only want a method to activate if the pixel that is clicked is white. How woul开发者_开发问答d I implement this? Trying to look for a method that returns the colour at a coord, but I can't find one.
Depends. If you have got a BufferedImage (or some other Image) you can use its getRGB
methods (or getRaster().getPixel
). If you haven't, you can use JPanel's createImage
methods and use the returned image to get the pixel data.
