hq2x implementation?

Java 2D
#1

Has anybody seen or written an implementation of the hq2x image filter in Java?

For those of you who don’t know what this is, hq2x is a very high quality scaling/magnification filter that’s commonly used in emulators to allow games to have their resolution increased without a sacrifice in quality. It’s like Scale 2x but 10x better and a lot more complicated to implement.

You can read more about it here. http://www.hiend3d.com/hq2x.html

They do provide source, but it’s convoluted to say the least.

It was ment as a pointer to some related topic :wink:

So, yea I wa aware of the visual differences, but the scale2/3x thing is something he could have used in the meantime.
