For those who know Photoshop, you can change the mode of the image; Normal, Dissolve, Darken, Multiply, Screen etc.

Is there a way to do this with in Java?

That looks like modulate to me.

dstColor*=srcColor;


Ofcourse I'm wrong - that is nothing like a modulate =)

In java2d there are those composite modes and over in opengl you have blend funcs (in this case it would be GL_ONE, GL_ONE).

I'm doing something like this, and doesnt work:

1  
2  
3  
4  
5  
6  
7  
8  
9  
10  
11  
...
AlphaComposite originalComposite = (AlphaComposite)g.getComposite();
g.setComposite(makeComposite(0.5F)); // 50% transparent
g.drawImage(...);
g.setComposite(originalComposite);
..

private AlphaComposite makeComposite(float alpha) {
   int type = AlphaComposite.SRC;
   return(AlphaComposite.getInstance(type, alpha));
}


This is all very new to me...any help appreciated. What do I change to make it work as intended?

Amazing what a quick google can find.

http://www.pegtop.net/delphi/blendmodes/

As to how to implement that in Java - implement the Composite interface, and define your own compositing rule. (you will in turn have to define a CompositeContext - with the necessary magic in the compose(Raster src, Raster dst, WritableRaster dstOut) method.

It won't be quick though (so don't use it in a real-time animation).
