Exception when trying to import a file generated with the PdfProcessing library from HTML

Using the COUNTIF function throws an exception if the criteria parameter is set to "<>".

If a conditional formatting rule with formula is set to "B1=True" and the cell B1 has value "false", the formatting will still be applied.

Missing content when converting a specific PDF to images (mostly text and shapes).

Images are decompressed during import/export which result in significantly larger files

The image stream is not compressed resulting in a bigger size of the generated file.

Importing a TOC field with /t switch (containing a style like "Heading 1") causes IndexOutOfRangeException.

The Table Of Contents (TOC) is populated with additional elements when StyleLevel is set.

When opened in Adobe Reader it says that the file "claims compliance". However, when verifying the compliance with some validation tools there seem to be some issues mainly related but not limited to fonts. 

Add a setting that allows enabling printing of protected documents.

After signing a document using the PdfProcessing library and the document is loaded in Adobe Acrobat an error is shown when the signature widget is clicked:
Error during signature verification.  

Adobe Acrobat error.
Expected a dict object.

InvalidOperationException (Sequence contains no elements) when updating TOC field in a document

When importing documents with more than one cross-reference table that have not Prev tables specified the incorrect table is processed.

Wrong matrix calculations lead to incorrect image (Form XObject) during export

Add support for shapes, and especially for shapes with textual content. 
In OOXML, shapes are represented by the wps:wsp element, and shapes with textual content by <wps:txbx>, <w:txbxContent>.
Such shape can be added to a Word document using the Insert -> Text -> Text Box -> Draw Text Box, or through a shape's context menu -> Add Text.

Do not confuse these shapes with Text/Rich Text content controls (see https://feedback.telerik.com/Project/184/Feedback/Details/190057 )
