upsimage.cgi - Image‐generating helper for upsstats.cgi
As a CGI program, this should be invoked through your web server. If
you run it from the command line, it will either complain about
unauthorized access or spew a PNG at you.
upsimage.cgi generates the graphical bars that make up the right side
of the page generated by upsstats.cgi(8). These represent the current
battery charge, utility voltage, and UPS load where available.
The images are in PNG format, and are created by linking to Boutell’s
excellent gd library.
upsstats will only talk to upsd(8) servers that have been defined in
your hosts.conf(5). If it complains about "Access to that host is not
authorized", check that file first.
