WordsProcessing: Add support for TextDirection of table cell when exporting to pdf
Last Updated: 28 Sep 2022 13:41 by Martin

When exporting a document that contains a Widget created with FixedContentEditor an exception is thrown: System.ArgumentNullException: 'Value cannot be null. Parameter name: context'

It can be reproduced using the following code snippet:

RadFixedDocument document = new RadFixedDocument();
var page = document.Pages.AddPage();
FixedContentEditor editor = new FixedContentEditor(page);

PushButtonField pushButton = new PushButtonField("button");
editor.Position.Translate(20, 450);
editor.DrawWidget(pushButton, new Size(100, 20));

string path = "Exported.pdf";

using (Stream output = File.OpenWrite(path))
	PdfFormatProvider provider = new PdfFormatProvider();
	provider.Export(document, output);

Workaround: Add the form filed to the AcroForm`s FromFields collection before exporting the document:

From the PDF Specification: "An ink annotation represents a freehand “scribble” composed of one or more disjoint paths. When opened, it displays a pop-up window containing the text of the associated note."

Currently RadFixedDocumentInfo is used only for export of Author, Title and Description document metadata properties. This should be extended to support custom properties. We should also implement the import of RadFixedDocumentInfo.

PDF/A-1a is with conformance level A (for "accessibility"), and must adhere to all of the requirements of the PDF Reference as modified by the ISO 19005 specification. 

It requires structural and semantic properties to be preserved. Level 1a uses “Tagged PDF” and Unicode character maps to preserve the document's logical structure and content text stream in natural reading order. 

The following features are used:
- Language specification
- Hierarchical document structure
- Tagged text spans and descriptive text for images and symbols
- Character mappings to Unicode

The purpose is to improve accessibility and make the content accessible for screen readers.

Currently, when users need to add content to an existing page that is rotated, they should manually calculate the positions of the new content if they need to align it with the appearance of the page. Add API allowing them to easily transform the position respecting the top left edge of the page after its rotation.

Currently, for .NET Framework scenarios, this could be achieved using RadPdfViewer's WPF control ThumbnailFactory class. Sample code may be seen at this forum post: http://www.telerik.com/forums/pdf-thumbnail-returns-transparent-images#jO33X-E8Cki_qLh_KsToWg.

The feature should be implemented for .NET Standard as well.

When using the PdfStreamWriter to write a PdfPageSource whose content has "Predictor 1" set as DecodeParms an error message is shown when opening the exported document with Adobe reader.

Provide API or mechanism for reusing the already embedded fonts instead of creating a new one when editing an existing document. 

This causes an issue in adobe preflight (font name is not unique).  


The issue is observed when performing merge with RadFixedDocument as well.

Support for exporting WMF (Windows Metafile) and EMF (Enhanced Metafile) images should be implemented.

Workaround: Convert the WMF images to PNG before exporting:
ImageSource imageSource = new ImageSource(new MemoryStream(this.ConvertWmfImageToPng(stream)));
private byte[] ConvertWmfImageToPng(Stream wmfImageStream)
    byte[] pngBytes;
    using (MemoryStream pngImageStream = new MemoryStream())
        System.Drawing.Image imageDrawing = System.Drawing.Image.FromStream(wmfImageStream);
        imageDrawing.Save(pngImageStream, System.Drawing.Imaging.ImageFormat.Png);
        pngBytes = pngImageStream.ToArray();
    return pngBytes;
