If the font family name is defined using a language other than English, the font is not applied to the content. This also can affect the performance as the font is read but it is not registered in the FontsRepository.

These permissions are defined on a document level and apply permission handlers. The permission handlers are similar to the security handlers but do not require the document to be encrypted. They are also used to determine which objects are to be included in the digest calculation used for the digital signature functionality.

By specification the destination string can be a string of up to 512 bytes. However, the current implementation supports strings of up to four bytes which leads to: ArgumentOutOfRangeException: 'bytes should be less or equal than 4.Parameter name: bytes'.

When there is a destination object in a RadFixedDocument and it doesn't have page set (it is null), an exception is thrown. However, this is supported by Adobe and it is not forbidden in the Pdf specification.

According to the specification, the startfref keyword must be followed by the offset the xref table start on, defined on a new line. Some documents, however, have both entries defined on the same line, which leads to InvalidOperationException with message "Stack empty" while importing. Make sure this case is handled in PdfProcessing as well.

When a TrueType font is defined, the mapping of character codes to glyph indices depends on the built-in cmap table mappings defined in the font and the Encoding property defined in the PDF dictionary.

However, the current implementation maps all characters with cmap tables for Microsoft Symbolic and Macintosh Roman, which causes incorrect mapping results, e.g. space characters are mapped to an Ê glyph.

The issue is also described in the following public item: TryGetCharCode for OpenTypeFont uses wrong cmap and returns wrong charcode.

Workaround: Change the font  of the TextBoxField's widget appearance:
foreach (var widget in field.Widgets)
{
    widget.TextProperties.Font = FontsRepository.Helvetica;
}

In principle, the blend function B (Cb , Cs ) is used in the compositing formula to customize the blending operation in Adobe transparency imaging model. The blending mode may define any function which yields another result color from the backdrop and source colors. This will allow overlaying objects on each other forming a transparency stack.

Support for the Blend Mode parameter of the external graphic state should be implemented.

Currently adding an Image content element with ImageSource instantiated with a PNG file format leads to NotSupportedException: 'Can not export other than Jpeg and Jpeg2000 and ImageQuality different than High', when exporting the document.

Support for adding PNG images and exporting to PDF should be implemented for PdfProcessing for .NET Standard scenario.

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)));
document.Pages.AddPage().Content.AddImage(imageSource);
...
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;
}

When merging files the documents might have the same fonts embedded. Then the PdfProcessing should use only one of the fonts and skip embedding the second font in the resulting document.
