Can GhostScript run in Medium Trust?

I am using GhostScript to generate some thumbnails of PDF pages in an ASP.NET application. I have it wrapped in this library called GhostScriptSharp that just uses DllImport to call methods in the GhostScript DLL.

It looks like this wont work on a medium trust hosting environment, either because of the fact that it is calling unmanaged code, or that it looks like the libr开发者_StackOverflow中文版ary is creating files all over the place (outside my virtual directory).

I ran Process Monitor and saw it trying to Read, QueryNameInformationFile, CreateFile and QueryStandardInformationFile in places like:

C:\WINDOWS\system32\Halftone\Default or C:\gs\gs8.63\lib\Halftone\Default or C:\gs\font\Halftone\Default

Any ideas about whether this is "fixable" to run in medium trust?

If I can't use GhostScript, is there another free/open source library that WILL work in Medium trust?

From what I understand, Medium Trust does not allow for Unmanaged Code to be run.

Therefore, GhostScript will not work in Medium Trust. (At least at the time of this answer.)
