Hi,
i have created a pdf with syncfusion tools and it seems invalid.
The code for PdfDocument creation is the following
Dim pdfDocument As New PdfDocument(PdfConformanceLevel.Pdf_A1B)
pdfDocument.FileStructure.Version = PdfVersion.Version1_4
pdfDocument.FileStructure.CrossReferenceType = PdfCrossReferenceType.CrossReferenceTable
The code for PdfFont creation is the following
...
Dim font As System.Drawing.Font = New System.Drawing.Font(name, size, fontStyle)
Dim pdfFont As New PdfTrueTypeFont(font, True)
The result is that when i open the PDF file in AcrobatReader it seems a valid PdfA but NOT when i analyze it with Adobe Acrobat Pro.
I've attached a zip with the PDF created with Syncfusion and an image with the result of Adobe Acrobat Pro.
Regards,
Stefano
