Hi to everybody of the support team,

the attached word document causes problems.

Aspose.Words Version 9.7.0

Example code

private static void Test_SaveAsPng(string strSourceFile)
{
    string strDestFile = Path.ChangeExtension(strSourceFile, "png");

    if (File.Exists(strDestFile))
    {
        File.Delete(strDestFile);
    }

    // Loading document causes exception ...
    LoadOptions lOpt = new LoadOptions(LoadFormat.Doc, null, null);
    Aspose.Words.Document currDoc = new Aspose.Words.Document(strSourceFile, lOpt);

    currDoc.ShadeFormData = false;
    ImageSaveOptions imageSaveOpt = (ImageSaveOptions)Aspose.Words.Saving.SaveOptions.CreateSaveOptions(Aspose.Words.SaveFormat.Png);
    imageSaveOpt.PageCount = 1;
    imageSaveOpt.PageIndex = 0;
    imageSaveOpt.Resolution = 100;
    imageSaveOpt.SaveFormat = Aspose.Words.SaveFormat.Png;

    if (currDoc.PageCount > 0)
    {
        SaveOutputParameters savedOutput = currDoc.Save(strDestFile, imageSaveOpt);
    }
}

Same exception occurs, when document is converted to pdf.

Example code:

private static void Test_SaveAsPdf(string strSourceFile)
{
    string strDestFile = Path.ChangeExtension(strSourceFile, "pdf");

    if (File.Exists(strDestFile))
    {
        File.Delete(strDestFile);
    }

    // Loading document causes exception ...
    LoadOptions lOpt = new LoadOptions(LoadFormat.Doc, null, null);
    Aspose.Words.Document currDoc = new Aspose.Words.Document(strSourceFile, lOpt);

    currDoc.ShadeFormData = false;

    PdfSaveOptions pdfSaveOpt = (PdfSaveOptions) Aspose.Words.Saving.SaveOptions.CreateSaveOptions(Aspose.Words.SaveFormat.Pdf);
    pdfSaveOpt.Compliance = PdfCompliance.Pdf15;
    pdfSaveOpt.BookmarksOutlineLevel = 3;
    pdfSaveOpt.HeadingsOutlineLevels = 3;
    pdfSaveOpt.SaveFormat = Aspose.Words.SaveFormat.Pdf;

    SaveOutputParameters savedOutput = currDoc.Save(strDestFile, pdfSaveOpt);
}

Hello

Thank you for reporting this problem to us. I managed to reproduce the problem on my side. Your request has been linked to the appropriate issue. You will be notified as soon as it is fixed.
It seems the reason of the problem is the following construction inside the footer of the document {IF {PAGE} <> {NUMPAGES} …}. As a workaround, you should change this construction like this {IF {PAGE} <> {NUMPAGES} “…”}
Best regards,

The error still exists with Aspose.Words 9.8.0.0. When the method PageCount is called the following exception is thrown.
