Table columns are not the expected width after export while having large cropped images as content and all table content is resized. The input document's images are not resized and are too big to fit on the table and thus are cropped. 

Expose a way to add new shapes to the document, modify them, or delete them.

InvalidOperationException caused by some PageNumberType formats.

Bolding of some content on Import/Export. 

Cannot import a document containing style with no name.

Preserve Footnotes/Endnotes information.

TOC list numbering and page numbering are missing.

Generate a document with the following approach: https://docs.telerik.com/devtools/document-processing/knowledge-base/populate-table-data-mail-merge

Before calling MailMerge, add two document variables with the editor: https://docs.telerik.com/devtools/document-processing/libraries/radwordsprocessing/concepts/fields/document-variables 

 

When a style doesn't have explicitly defined font, the font from the default character properties (\defchp) is used when present. Instead, the font used for the style should be the default font for the document, defined with \deffN tag.
The same issue occur when the doesn't contain \defchp at all. In this case, the font for the style is not imported, but instead the defined with  \deffN tag should be used.

The construction is not common, and MS Word for example doesn't produce such documents.

When a paragraph has defined tab stops in its style and has the same tab stops locally cleared, the tab stops are still respected when exporting to PDF. Instead, cleared tab stops should not be respected.

Workaround:
Copy the default styles after the Mail Merge

RadFlowDocument merged = sourceDocument.MailMerge(mailMergeSource);
merged.DefaultStyle.ParagraphProperties.CopyPropertiesFrom(sourceDocument.DefaultStyle.ParagraphProperties);
merged.DefaultStyle.CharacterProperties.CopyPropertiesFrom(sourceDocument.DefaultStyle.CharacterProperties);

If the value from the source contains new lines, they should be inserted in the resulting documents as new paragraphs.

The <font> tag has a 'size' attribute that can be set to a number from 1 to 17. This is currently not supported and is just ignored.

CSS style property with a numeric value will not be imported from HTML when the unit type is not specified. Example: .td{padding-bottom: 200;}

This is invalid according to the HTML spec (value is optional only after 0), though web browsers and MS Word open such HTML's correctly.

In specific situations, a paragraph in a table cell which is last on a document page is not exported to the PDF document.
Possible workaround is adding a new paragraph to the last table cell before exporting the document.
For instance:
BlockCollection footerContent = this.document.Sections.First().Footers.Default.Blocks;
Table footerTable = footerContent.First() as Table;
footerTable.Rows.Last().Cells.First().Blocks.AddParagraph();

Import styling properties from HTML for elements without DocumentElementProperties. For example, for ImageInline: the image has width and height and currently they could not be applied through CSS styling as the styling mechanism works only for document elements with DocumentElementPropertiesBase (RadFlowDocument, Section, Table, Paragraph, etc.)

Implement API allowing to add watermarks without specifying its width and the height. The size could be automatically calculated using the text, its font size and font family.

The text of the watermark is exported with the default font family due to incorrect escaping while writing the OpenXML.
