This element specifies the settings for the document grid, which enables precise layout of full-width East Asian language characters within a document by specifying the desired number of characters per line and lines per page for all East Asian text content in this section.

If Latin text is interspersed on this line, then it is placed across the number of grid units needed to fit the
content, but all other grid positions are unaffected.

In a DOCX document, the users can define an image which is bigger than the size of the page. When such an image is at the beginning of the document and is converted with PdfFormatProvider, an additional page is added in the result PDF.

foreach (var image in document.EnumerateChildrenOfType<ImageInline>())
{
    var section = image.Paragraph.Parent as Section;
    if (image.Image.Height > section.PageSize.Height - section.PageMargins.Top - section.PageMargins.Bottom)
    {
        var height = section.PageSize.Height - section.PageMargins.Top - section.PageMargins.Bottom - (image.Paragraph.Spacing.SpacingAfter * (image.Paragraph.Spacing.LineSpacing - 0.97));
        image.Image.Size = new System.Windows.Size(image.Image.Width, height);
    }
}

When a HTML has a wrong encoding set (content="text/html; charset=utf-16") we use the UTF-16 encoding when importing this HTML. This leads to wrong import. 
Microsoft Word detects that the set encoding is wrong and uses UTF-8 instead so that the imported result is correct. 

The HTML5 specification forbids the use of the meta element to declare UTF-16, because the values must be ASCII-compatible: https://www.w3.org/International/questions/qa-html-encoding-declarations#utf16 

When the value in the document variable collection and the argument of the DOCVARIABLE fields are with different casing, the field is not updated.

Available in LIB Version 2018.3.1029.

In the current implementation, the parent of a hyperlink must be a paragraph. Otherwise, a NullReferenceException is thrown.

This element serves as a frame and allows the element to be positioned as a floating element. More information about it is available in section 22.9.2.18 ST_XAlign (Horizontal Alignment Location) of Open Office XML.
DECLINED: Duplicate with - Implement support for Text Frame Properties.

When importing documents containing pictures with references represented with the r:link attribute, ArgumentNullException is thrown.

Implement support for pictures with references represented with the r:link attribute in the schema.

Enable the customers to import SVG images and use them in their documents.

Implement support for footers in HtmlFormatProvider.

Enable the customers to add digital signatures to the documents and read signed documents.

When a document containing a field without a separator is inserted using the RadFlowDocumentEditor.InsertDocument(*) method, NullRferenceException is thrown.

Workaround: Fix the document before inserting: 

private static void WorkaroundFieldsIssue(RadFlowDocument flowdocument)
{
    foreach (FieldCharacter fieldCharacter in flowdocument.EnumerateChildrenOfType<FieldCharacter>().ToList())
    {
        // only for start
        if (fieldCharacter.FieldCharacterType == FieldCharacterType.Start)
        {
            if (fieldCharacter.FieldInfo.Separator != null && fieldCharacter.FieldInfo.Separator.Parent == null)
            {
                Paragraph parent = fieldCharacter.FieldInfo.End.Paragraph;
                int index = parent.Inlines.IndexOf(fieldCharacter.FieldInfo.End);

                fieldCharacter.FieldInfo.End.Paragraph.Inlines.Insert(index, fieldCharacter.FieldInfo.Separator);
            }
        }
    }
}

LineInfo objects are not cleared when there are tables in the document being exported to PDF which leads to OutOfMemoryException.

When the table borders are None, and each cell has custom set borders, when cells are merged, only borders of the cell that has <w:vMerge w:val="restart"/> are imported.

When the document contains an image with extension, which is not among the supported ones, a KeyNotFoundException is thrown during Import.

When exporting a nested table, which is inside a table with cells whose sum of widths is more than 100%, the last cells are missing from the exported with PdfFormatProvider document.

The issue is not observable in the other format providers.

Add support for importing HTML with syntax <img style="width: 300px; height: 300px;" /> At the moment only HTML attributes are supported.

Currently, the align attribute is supported only for a table and when applied to a cell or row is omitted on import.
