Hello,

if we try load a document with input fields in the viewer,
our app crashes with an unhandled ArgumentOutOfRangeException
thrown inside the LoadDocument-Method.

Exception:

Argument out of range (param name "index")


Stack Trace:

at System.ThrowHelper.ThrowArgumentOutOfRangeException(ExceptionArgument argument, ExceptionResource resource)
at Patagames.Pdf.Net.PdfForms.FFI_GetPageCallback(FPDF_FORMFILLINFO pThis, IntPtr document, Int32 nPageIndex)



(Patagames.Pdf.Net.Controls.Wpf.PdfViewer)
(Patagames.Pdf.Wpf 3.8.1, Patagames.Pdf 3.8.1.2704)
(.NET-Framework 4.6.1).

Is this a known or already fixed behaviour or are their any chances for a quick fix?

Thanks for the quick and helpful response.

You can set back the FormsBlendMode property to FXDIB_BLEND_MULTIPLY

The document that you submitted earlier (10014416729_1_Kontoloschung-Vorlage+Coba.pdf) contains abnormal text annotations that will not be displayed correctly in this case.
At the moment we are working on finding a solution of that problem.
Thanks!
