Observed:
When importing a document with empty pages collection an ArgumentNullException: 'Value cannot be null.
Parameter name: page', is thrown, which leads to application crash.
Workaround: Import the document using the PdfProcessing library and add an empty page:
PdfFormatProvider pdfProcessingFormatProvider =
new
PdfFormatProvider();
RadFixedDocument document = pdfProcessingFormatProvider.Import(stream);
if
(document.Pages.Count == 0)
{
document.Pages.AddPage();
}
Document cannot be loaded because the Encrypt property is not set and is null.
The UserDict collection is not parsed and the procedures for the operators are unavailable. The exception is thrown while trying to read the font file of the Univers and Univers Bold fonts. Internally, an ArgumenNullException is thrown, which results in missing content when the document is shown in RadPdfViewer.
All annotations are missing because ArgumentNullException is thrown while importing page annotations. The exception is handled and all non-annotation related pdf content is loaded successfully.
