I have the XBoard SVG piece images on my website, at http://hgm.nubati.net/svg/ . It should be relatively easy for me to copy-paste the XBoard code for rendering these pieces to a bitmap (written in plain C) into a CGI program that then outputs it as PGN of a specified size. But I got stuck doing that. I have access to only 3 Linux machines: the one I use for development, running in VirtualBox, which has no web-server running on it. Then I have some webspace I borrow from a former collaborator on XBoard, where I have the XBoard development website on a Linux machine, including my git source repository. I have several CGI programs running there, but I cannot run any SVG stuff there, as librsvg-2 doesn't seem to be installed, and I have no root permission I can use there to install anything. Finally I have my own web server running on a VPS I rent (winboard.nl). I did not manage to run any new CGI program there (even those which tested OK on the XBoard website). Behavior there seems quite sick: I have gitweb.cgi running there to put a mirror of my git repository online, at winboard.nl/cgi-bin/gitweb.cgi . This works fine, despite the fact that gitweb.cgi DOES NOT EXIST, and the cgi-bin directory is entirely empty! If I place other CGI programs in the cgi-bin directory, or even just png images, and try to access these through the web server (lighttpd) with an URL, GitWeb starts running instead, browsing my repository?!? If I place CGI programs in another place in the www tree, they do not seem to run correctly, and produce a blank page when accessed through their URL. I wonder if the machine is somehow hacked.
So I am stuck. I can write a CGI program to produce scaled (or colored) pieces, but I cannot run it where I have a web server, and cannot test it where I can compile it...
