A pop-up annotation displays text in a pop-up window for entry and editing. It typically does not appear alone but is associated with a markup annotation (its parent annotation) and is used for editing the parent’s text.

By specification, the last line of the file contains only the end-of-file marker, %%EOF. If the file contains many trailing bytes at its end, a NotSupportedException: 'StartXRef keyword cannot be found.', is thrown.

Workaround: Trim any content after the end-of-file marker (see FixInvalidEndOfFile).

This would allow to encrypt documents only with Owner Password and not showing password dialog when disabling some PDF features permissions. The customer should be able to disable printing, text and graphic selection and extraction, page rotations and others. The full specification of all permission bits may be seen in Table 3.20 on page 124 in PdfReference 1.7. On page 120 in PdfReference 1.7 are described the User and Owner passwords.

When merging documents containing the same embedded font every time a document is merged the same font is repeatedly embedded in the merged document. This leads to very large files.

A possible workaround before this feature is developed could be to use the PdfProcessing model to import and merge the documents. After the documents are merged to iterate the document`s content in order to cache the fonts using their name and if there are duplicated names to set the already cached one (check the attached project). 

As a side note, the suggested workaround doesn't cover all possible cases (e.g. if there are fonts with a common name but different font sets (modified fonts or font subsets) this may lead to missing/different characters in the produced document). So in order to use this workaround, you will need to ensure the font names are unique for every different font.

For example when some PDF file has uncompressed contents we may import it and apply better compression to the stream objects. Ensure that all the content inside the document is compressed.

Currently, importing a document with non-embedded TrueType font will result in a font instance with an empty font source. Support should be added for providing custom font data of TrueType fonts during document import.

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

To allow the library to export such images you can use the extensibility point for providing a custom implementation of the JpegImageConverterBase. More information and examples can be found in the PdfProcessing`s Cross-Platform Support help and Create Custom JpegImageConverter in .Net Standard knowledge base articles.

or there should be an optional parameter "bool AcceptNewlines" or "bool IgnoreNewlines"

 

Currently, this can be implemented like this:

private void InsertTextWithNewlines(Block block, string text)
{
    string[] lines = text.Split(new[] {"\r\n", "\r", "\n"}, StringSplitOptions.None);

    for (int i = 0; i < lines.Length; i++)
    {
       block.InsertText(lines[i]);
       if (i < lines.Length - 1)
       {
          block.InsertLineBreak();
       }
    }
}

According to the PDF specification:
A clipping path operator (W or W*) may appear after the last path construction operator and before the path-painting operator that terminates a path object.

Invalid:

W                          % clipping path operator
0 0 m                     % start of the path construction
596 0 l
596 842 l
0 842 l
h                            % end of the path construction
n                            % path-painting operator
Valid:
0 0 m
596 0 l
596 842 l
0 842 l
h
W
n

Currently (in the invalid cases), the path construction is skipped on import.
