PdfReport with different Fonts

    we create C1PrintDocuments and add them to a C1MultiDocument. Then, we export the C1MultiDocument as a PDF to disk.

    After migrating to Windows10, we observe a strange behaviour. The exported PDF contains pages with different fonts altough we define the same font (name and size) for each C1PrintDocument.

    The behaviour can not be reproduced deterministically. This means, one time the font differs on page 1 and page 3, an other time the font differs only on page 2. And sometimes the font do not differ at all.

    Here is how we create the C1PrintDocument

    C1PrintDocument.UsePrinterForDefaultPageSettings = False

    Dim doc As C1PrintDocument = New C1PrintDocument()
    doc.CreationDpi = dpi
    doc.FontHandling = FontHandling.EmbedFonts
    doc.Style.Font = New Font("Courier New", 9, GraphicsUnit.Point)
    doc.PageLayouts.Default.PageSettings.PaperKind = PaperKind.A4
    doc.PageLayouts.Default.PageSettings.TopMargin = New Unit(0.5, UnitTypeEnum.Cm)
    doc.PageLayouts.Default.PageSettings.BottomMargin = New Unit(1, UnitTypeEnum.Cm)
    doc.PageLayouts.Default.PageSettings.LeftMargin = New Unit(2, UnitTypeEnum.Cm)
    doc.PageLayouts.Default.PageSettings.RightMargin = New Unit(1.3, UnitTypeEnum.Cm)

    Dim cr As RenderText = New RenderText()
    doc.PageLayouts.Default.Overlay = cr

    Return doc

    Additional Information:

    I found out that some fonts are missing in the exported PDF file altough they are added as embeddedfont in the C1PrintDocuments (FontHandling.EmbedFonts).

    We use the following fonts:

    • Arial

    • Arial Narrow

    • Courier New

    • Courier New, Bold

    It is not deterministic which and how many fonts are missing.

    Hello Mohit,

    I added a test project with a test class MultiDocumentsTest.

    It generates and exports a higher amount of C1MultiDocuments containing one C1PrintDocument. Each C1PrintDocument consists of RenderTexts and RenderTables. The texts are styled with different fonts.

    Strange is:
    If I copy the test into your application and start it, all pdf look fine. But as soon as I execute the test itself, fonts are missing in some of the exported pdfs.

    I am able to reproduce the issue at my end. I have escalated the issue to our development team (434479) and will inform you once I get any information from them.

    Hello Mohit,

    thanks for escalating to your development team.
    I hope there will be a fix soon because my customer sends those PDFs to its own customers and therefore requires a universal style for all the PDFs

    Hello Mohit,

    did you receive any feedback from your developer team so far?
    It is pretty urgent since we want to release within the next month and the non working report generation is a deal-breaker.

    Best regards
