When exporting merged documents when they are imported with ImportSettings set to ReadOnDemand an exception is thrown: KeyNotFoundException: 'The given key was not present in the dictionary.'

When a document containing a SignatureField is exported with the IsEncrypted property set to true, a not set UserPassword is required to open it, which makes it impossible to be opened. An InvalidOperationException is thrown with the message "Password is not correct." when importing with PdfProcessing; Adobe Acrobat also doesn't recognize the password.

Workaround: Exporting with AES256 encryption does not have this problem:

provider.ExportSettings = new PdfExportSettings
{
	IsEncrypted = true,
	EncryptionType = EncryptionType.AES256
};

This could be implemented by linking to RadFixedPages or Bookmarks.

Until this feature is developed this could be custom created with the help of Link annotations:

RadFixedPage toc = new RadFixedPage();
document1.Pages.Insert(0, toc);

FixedContentEditor editor = new FixedContentEditor(toc);

foreach (RadFixedPage page in document1.Pages)
{
	int pageNumber = document1.Pages.IndexOf(page);

	if (pageNumber > 0)
	{
		int factor = 20;

		int offsetX = 70;
		int offsetY = 20 + factor * pageNumber;
		editor.Position.Translate(offsetX, offsetY);

		Block block = new Block();
		block.GraphicProperties.FillColor = new RgbColor(255, 5, 99, 193);
		block.InsertText($"Page {pageNumber}");
		Size blockSize = block.Measure();
		editor.DrawBlock(block);

		Location location = new Location
		{
			Left = 0,
			Top = 0,
			Zoom = 0,
			Page = page
		};

		GoToAction goToAction = new GoToAction();
		goToAction.Destination = location;

		Link uriLink = toc.Annotations.AddLink(goToAction);
		uriLink.Rect = new Rect(offsetX, offsetY, blockSize.Width, blockSize.Height);
	}
}

According to the PDF Specification: A redaction annotation (PDF 1.7) identifies content that is intended to be removed from the document.

There are two possible options to workaround this functionality:

1. To iterate the document content and replace the matches which meet certain conditions with an empty string:

   foreach (RadFixedPage page in document.Pages)
   {
   	foreach (ContentElementBase elementBase in page.Content)
   	{
   		if (elementBase is TextFragment textFragment)
   		{
   			if (IsValidEmail(textFragment.Text))
   			{
   				textFragment.Text = string.Empty;
   			}
   		}
   	}
   }

   Note: the desired content could be split into several text fragments and if so a custom parser should be created.
   
2. To iterate the document content and check if the TextFragment position is within a specific RectangleGeometry: 
   

   foreach (RadFixedPage page in document.Pages)
   {
   	foreach (ContentElementBase elementBase in page.Content)
   	{
   		if (elementBase is TextFragment textFragment)
   		{
   			if (IsIntersecting(rectangleGeometry, textFragment))
   			{
   				textFragment.Text = string.Empty;
   			}
   		}
   	}
   }

   Note: it should be taken into account that the text fragment could flow out of the rectangle.

Hello Support,

I am generating pdf using PdfFormatProvider. In this i am passing html data which should be converted into pdf. For that I have written below code.

HtmlFormatProvider htmlFormatProvider = new HtmlFormatProvider();

RadFlowDocument htmlDocument = htmlFormatProvider.Import(htmlContentValue);

 var anotherpara = sectionBody.Blocks.AddParagraph();

editor.MoveToParagraphStart(anotherpara);

editor.InsertDocument(htmlDocument, options);

This works fine and also get pdf with expected value. But I would like to set spacing between two lines which I could not set or its not working. For that I have added below code.

I have also attached screenshot for it. like how its showing on pdf

editor.ParagraphFormatting.AutomaticSpacingAfter.LocalValue = false;
editor.ParagraphFormatting.AutomaticSpacingBefore.LocalValue = false;
editor.ParagraphFormatting.SpacingAfter.LocalValue = 0;
editor.ParagraphFormatting.SpacingBefore.LocalValue = 0;

So could you please let me know fix for it.

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?
