the problem with using the gdi library is that it is not free threaded.
this means that one asp.net request could block another (as some
routines can only be used one thread ata time). this can cause a
performance problem. there is also small chance with async processing a
webrequest could block it self. you can avoid this by setting aspcompat
on (which limits a webrequest to one thread) and again limits
performance. the aspcompat feature is not available to web services.


another minor problem is you could call a routine that accesses the
desktop, and of course this would throw an exception.
