Manipulate color of screen pixel
<p>as the title says, I try to manipulate the color of each pixel on the screen, because I want to make a filter, so that the screen appears to be just black and white. My idea was to create a Frame, take the color of the pixel and write the result to the Frame. I use Processing for the code, but I think you can figure it out:

<p>The problem is of course that I also record the Frame and the result is displayed multiple times. I can't hide the Frame before I take the screenshot because you can see the window flickering.</p>

<p>Are their any better solutions or ideas?
Thanks in advance.</p>
