Jin chess pieces, how to obtain higher resolution? There are a set of good chess piece graphics at: https://code.google.com/p/raptor-chess-interface/wiki/AdditionalChessSets. In particular, I'm interested in the graphics used by the Jin Chess client, e.g.: JinAlpha.




Unfortunately, the highest resolution is at 132x132, which is too little in the 2015 standards. I'm looking for something like 256x256, or even SVG (resolution independent).

Anybody has any idea where to get the source for the graphics (e.g.: Adobe files)? Who created those graphics? Is there any way to increase the resolution without image loss? Who would have the skills to enhance the graphics?

Free or paid solutions are welcome.
I found this link to Github which could be useful: https://github.com/lukasmonk/lucaschess/tree/master/Pieces/JinAlpha

They seem to have the pieces in SVG format.
