System.OverflowException Arithmetic operation resulted in an overflow

[shawoozy]

Hola,

We scan PDF text and parse some data from it. The PDF provider randomly changed their font and now we keep getting this exception when the font type in a PDF is Hervetica or some similar one. Not sure what to do now.. I have attached the PDF that is failing.

A fix for this should go out in tonight's nightly build. Nightly builds are available at: https://www.nuget.org/packages/PdfPig.Nightly/

@EliotJones this particular exception is fixed, but now, using the nightly build we get another error when trying to generate a pdf.

UglyToad.PdfPig.Core.PdfDocumentFormatException Expected a IndirectReferenceToken for the XObject, got a DictionaryToken

@sharokh1 can you confirm your new issue is related to the old one? Maybe it's worth creating a new issue if this one is fixed.

Also, can you share a way to reproduce your new issue? What are you doing when you're creating the document.
