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();
}
