The experienced guys might be able to pin down something more specific, but
my next step here would be to try putting the same JSVGCanvas code on top of
a regular component like JFrame, to make sure that the file is actually
being read ok (I've had trouble in the past with file locations on windows,
I don't know if it would make any difference but substituting "d:/img1.svg"
might be worth a try). Maybe even just try inserting
System.out.println(f.exists());
Cheers,
Danny.
