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.

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

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.

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.

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

By specification, the InteractiveForm fields can have the same name if they are descendants of a common ancestor. Such fields are different representations of the same underlying field; they should differ only in properties that specify their visual appearance. When such a document is imported an ArgumentException: 'An item with the same key has already been added.' is thrown.

Telerik Pdf Processing Cannot open the attached pdf file and exception occur.

How do i slove it?

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

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

A submit-form action transmits the names and values of selected interactive form fields to a specified uniform resource locator (URL), presumably the address of a Web server that will process them and send back a response. Preserve the existing submit-form actions in the document and expose functionality enabling the users to create or modify such actions.

At this point, the setting paragraph Borders is not supported.

A possible workaround could be to draw a rectangle around the desired Block.

Currently, the ListLevel object doesn't provide an API for changing the passing of the Bullets.

Some documents result in glyphs with wrong widths after import-export. Widths are mixed making some of them to overlap and others to have bigger distance.
