Hi I'm a bit new to both asp.net and pdfSharp.

I'm trying to make some report pdf's and everything is nice and good. But now have I moved from my local server to the developing server, and have meet some issues.

I get a security exception:
Code:
Exception Details: System.Security.SecurityException: System.Security.Permissions.SecurityPermission

XFont pdfTitle = new XFont("Arial", 20, XFontStyle.BoldItalic);

I know I might solve this by changing the permissions.

But I would like to use the fonts from an external folder e.g ~/Resources/Fonts/
So I don't have to make the site more unsecured, due to some fonts.

How do I accomplish this? Any help would really be appreciated :)

And thx for the good library :D

Hi!

You can use a PrivateFontCollection to avoid this.

Using PDFsharp 1.3, PrivateFontCollection works in the WPF build.

Using PDFsharp 1.2, PrivateFontCollection works in the GDI+ build.

Sorry not to make everything more complicated. But I have just used the standard font from asp.net, to what seems, to be without problems:

Code:
Font pdfTitle = new Font("Arial", 20, FontStyle.Bold);
Font heading1 = new Font("Arial", 14, FontStyle.Bold);
Font heading2 = new Font("Arial", 12, FontStyle.Bold);
Font normal = new Font("Arial", 12, FontStyle.Regular);


But now I get another security problem:

Code:
XGraphics gfx = XGraphics.FromPdfPage(page);

And the stack if it helps:
Code:
[SecurityException: Request for the permission of type 'System.Security.Permissions.SecurityPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.]

   System.Web.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() +599
   System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) +171


So I really don't understand what there's going on? I would really like to get enlighten on this one :)
