I'm using GS 32bits with the wrapper for C# .
This line works :
GhostscriptSharp.GhostscriptWrapper.GeneratePageThumb("a.pdf" , "a.jpg", 1, 100, 100, 50, 50);
But this line doesn't work
GhostscriptSharp.GhostscriptWrapper.GeneratePageThumb("a.pdf" , "C:\a.jpg", 1, 100, 100, 50, 50);
How GS handle the in/out path ?
