When importing a document containing an invalid PDF object dictionary key an exception is thrown.

 

Exception when merging file that contains notdef characters with PdfStreamWriter

For example, importing URI Action with invalid mailto URL scheme - mailto:***@***.**(E-mail), throws UriFormatException: 'Invalid URI: The hostname could not be parsed.'

System.ArgumentException when setting a password to a document with form fields

This is reproducible with specific PDF files which use custom Encoding for the fonts of the field widgets. 

WORKAROUND: Change the font of VariableContentWidgets before editing the field value. You should additionally call RecalculateContent() method of these widgets if the value of their corresponding fields is not edited. The following method may be used for changing the font of all existing widgets in the document:

private static void FixEncodingIssues(RadFixedDocument document)
{
    foreach(Annotation annotation in document.Annotations)
    {
        VariableContentWidget widget = annotation as VariableContentWidget;

        if(widget != null)
        {
            widget.TextProperties.Font = FontsRepository.Helvetica;
        }
    }
}

Currently Type0Font class has CMap that can only be Identity-H.

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.

This is not a valid scenario, but Adobe Acrobat handles it and we should too. 

German umlauts (the characters 'Ä', 'Ö', 'Ü', 'ä', 'ö' and 'ü') will not be printed to a generated pdf file, but the other German "special" character "ß" works.

 

I use the trial version via the Telerik NuGet feed. A test program and my locally generated file are attached.

A remote go-to action is similar to an ordinary go-to action but jumps to a destination in another PDF file instead of the current file.

PdfProcessing: Signature field validation fails if a document is imported from a byte array of CopyStream property is false.

Workaround: Set the CopyStream property of the ImportSettings to true:

PdfFormatProvider formatProvider = new PdfFormatProvider();
formatProvider.ImportSettings.CopyStream = true;

Inserting a table with more than 10K rows is very slow.

Workaround: 

Use the following approach with SpreadStreamProcessing,SpreadProcessing and PdfProcessing:

 1) Generate an xlsx document with RadSpreadStreamProcessing 
 2) Import the document from 1) with RadSpreadProcessing 
 3) export 2) to PDF

The CIDToGIDMap value is exported as an indirect object. When the value is a PdfString ist should be directly exported and not referred as an indirect object. 

A StackOverflowException is thrown when cloning documents containing a page containing links to the same page. 

More information is available in the Pdf Reference 1.7. Page 442 lists all predefined CMaps that should be imported and exported as PdfName objects. At this point, trying to import a document with such encoding, a NotSupportedException is thrown with message Encoding type is not supported.

OutOfMemoryException has thrown when creating a thumbnail with the ThumbnailFactory.

This behavior is observed with binaries version 2020.2.513 or later.

In Adobe Acrobat, if you bring up the "Document Properties" dialog window and then click on the "Advanced" tab, there is a property under the "Print Dialog Presets" section called "Page Scaling". We should preserve the value on import/export and be able to set it in the code behind.

Importing document containing TextBox widgets with NormalContentSource defining text properties, such as FontSize and Position, are exported with incorrect appearance when the value of the field is modified.

The checkbox state is not correctly imported when the value is not specified

AcroForms are not saved when splitting a document into pages. This leads to forms not being recognized when the file is imported back.
