#142 Question

[Cris Teix]

Hey Karl, I'm aware (I think) you can specify a higher resolution than the webcam can handle since it's handled on the software side before its outputted to a virtual device.

In which case, what kind of upscaling/upsampling takes place (bilinear, right?), and could you maybe expose that option or implement more powerful algorithms for those of us with nice GPUs? It would be a major quality boost to be able to upscale using EWA_lanczos.

Then again I don't know if this is even a possibility because I don't know a lot about java.

Hi Cris,
WS use Java graphic2d and ImgScalr to resize the pictures:

I'm sorry, but i really don't know if EWA_lanczos method is usable in Java. I didn't find nothing useful, only this:

Maybe someone have a better knowledge about it.
Thanks.

I read the library's source code and it's pretty good at downscalling. I take it you used Method.ULTRA_QUALITY, Scalr.OP_ANTIALIAS.
I found another library which offered Lanczos3, but that's not good enough.

Thanks!
