Open a Pdf Containing Unsupported Actions

Attempting to open a Pdf document containing an unsupported action type results in a NotSupportedActionException being thrown (see PdfProcessing: Add support for actions of type Launch).


Can the behavior be changed to ignore unsupported actions and allow the document to be opened?

Hi Charles,

You can handle such exceptions using the exception handling mechanism described in the Handling Exceptions help article.

This is an example using the previously provided code snippet: 

using (Stream stream = File.OpenRead(inputFileName))
	PdfFormatProvider provider = new PdfFormatProvider();
	provider.ImportSettings.ReadingMode = ReadingMode.OnDemand;

	RadFixedDocument document = provider.Import(stream);

	document.DocumentUnhandledException += Document_DocumentUnhandledException;

	using (Stream ostream = File.OpenWrite(outputFileName))
		PdfFormatProvider expProvider = new PdfFormatProvider();
		expProvider.ExportSettings.ComplianceLevel = PdfComplianceLevel.None;
		expProvider.Export(document, ostream);

and the exception handler:

private static void Document_DocumentUnhandledException(object sender, DocumentUnhandledExceptionEventArgs e)
	if (e.Exception is NotSupportedActionException)
		e.Handled = true;

I updated the feature request public item with this information as well.

Do not hesitate to contact us if any additional questions arise.
