When applying a table or table cell border with no thickness specified, the border is exported with a default thickness value of zero. However, by specification, the default value should be 2.

Workaround: Create a border by specifying the thickness value. For example:

table.Borders = new TableBorders(new Border(thickness, BorderStyle.Single, new ThemableColor(Colors.Black)));

Trying to clone the Signature of a SignatureField leads to InvalidOperationException as the FieldName of the cloned signature is already set.

The API should allow you to perform a text-based search and return the parent element(s) of the result(s) or directly the found element(s).

I was working on some acroforms and wherever I needed a space I kept on getting a different letter (Ê). On debugging the problem seems to be in the TryGetCharCode function of OpenTypeFontSource

Version: 2019.3.917

Below is copy of function

public override bool TryGetCharCode(int unicode, out int charCode)
        {
            bool result = false;
            ushort glyphId;
            charCode = CMap.MISSING_GLYPH_ID;
            if (this.TryGetGlyphId(unicode, out glyphId))
            {
                ushort uCharCode = CMap.MISSING_GLYPH_ID;
                CMapTable table = this.CMap.GetCMapTable(3, 0);
                if (table != null)
                {
                    result = table.TryGetCharId(glyphId, out uCharCode);
                }

                table = this.CMap.GetCMapTable(1, 0);
                if (table != null)
                {
                    result = table.TryGetCharId(glyphId, out uCharCode);
                }

                charCode = uCharCode;

                return result;
            }

            return false;
        }

The font used has 2 cmap tables: one with platformid of 3 and encodingid of 1, the other with platformid 1 and encodingid 0. According to https://docs.microsoft.com/en-us/typography/opentype/spec/cmap platform id 3 and encoding 1 is correct for windows so not sure why the first call to getcmaptable looks for encodingid 0.

Second of all even if I change it to the following

CMapTable table = this.CMap.GetCMapTable(3, 1);

if there is a second cmap with platformid of 1 whatever the result of the call with regards to platformid 3, the result will be overridden

I can say that if I add some checks so that if the first call succeeds it doesn't attempt the 2nd I do get the expected behaviour in the pdf and get spaces

As a note the FontFamily property of the OpenTypeFontSource is "Arial"

In WordsProcessing on import only the lower case CSS attributes are correctly imported. Upper case and mixed case are ignored and the default values are used.

Filter Selection dialog appears on the screen. 

Workaround: Open the file with Excel and save it as a new document.

The property controls whether a paragraph should be rendered at least partially on the same page with the following paragraph when the document is shown in page view mode.

Add support for conditional formatting of cells - allow applying of rules used during visualization of cells to automatically apply formatting depending on their values.

The NuGet packages don't differ .Net Core projects from .Net Core with Desktop Compatibility Pack. This leads to incorrect resolving of the dependencies and the .Net Core projects targeting .Net Core 3.0 cannot be built.

Workaround: An option applicable for all the libraries is to extract the assemblies from the .nupkg files. For PdfProcessing and ZipLibrary you can use the assemblies directly from the pdfviewer installation folder.

This type of destinations is not supported and leads to InvalidCastException when importing such elements.
