Post subject: | PDfSharp and Unity |
Hello everybody, I have an issue on a specific usage and I hope someone will help me. I try to fill AcroForm on iOS app create with Unity (I know, it's weird, but I need Unity for AR development). In Unity Editor, everything work! The compilation on iOS work fine and no error with PDFSharp library. But in the app, when I try to read my original PDF I have this issue: Code: System.InvalidCastException: Unable to cast object of type 'PDFDictionary' to type 'PdfDocumentInformation'. at PDFSharp.Pdf.Advanced.PdfTrailer.get_info () ... at PdfSharp.Pdf.PdfDocument.get_info () .. at PdfSharp.Pdf.IO.PdfReader.Open(System.IO.Stream stream, System.String password, PDFSharp.Pdf.IO.PdfDocumentOpenMode openmode, PdfSharp.Pdf.IO.PdfPasswordProvider passwordProvider) ... at PdfSharp.Pdf.IO.PdfReader.Open(System.String path, System.String password, PDFSharp.Pdf.IO.PdfDocumentOpenMode openmode, PdfSharp.Pdf.IO.PdfPasswordProvider Provider) ... I try to read the pdf with PdfDocumentOpenMode.Modify. Someone have an idea? Thanks! Best regards, Alexis |

Hello, I'm using: PDFSharp 1.50.5147 (Nuget package here) Me code: Code: string path = "Devis_Client_Vierge.pdf"; string dest = "Devis-Test.pdf"; PdfDocument document = PdfReader.Open(path, PdfDocumentOpenMode.Modify); document.Save(dest); document.Close(); I found the problem come from IL2CPP scripting backend (not from PDFSharp library directely). If I use Mono scripting backend when I build me project, everything work. But when I use IL2CPP (And I need it for iOS app...), the issue appear. I will investigate in that direction! Sorry for your time. Best regards, Alexis |

Same here. Also happens when importing a PDF file and compiling with IL2CPP in Unity (Mono works fine). |
