Text fields should support rich text strings allowing the user to use rich text elements and attributes.

Currently, NotSupportedEncryptionException is thrown when PdfFileSource is initialized with an encrypted PDF file.

Available in R2 2018 Official Release Version.

The NotImplementedException is thrown while getting the color from unsupported color space (for example ICC). This exception occurs during the import of shading patterns with gradient stops using this color space or during the import of tiling pattern with underlying color space.

Available in R2 2018 Official Release Version.

Currently this operator is interpreted correctly only for Pattern colorspace. It also partially supports the rest of the colorspaces from R1 2018.

Available in R2 2018 Official Release Version.

The Matrix property seems to be incorrectly interpreted during the import process.

Implement the "k" and "K" color operators, which sets the color in DeviceCMYK color space. Currently graphics with color set with these operators are imported with incorrect colors.

Available in R2 2018 Official Release Version.

This includes loading form fields data from FDF file and saving the form fields data to FDF file.

This would ensure preserving the existing PDF file pages and document properties untouched and additionally would allow making a few modifications to the file. By appending bytes to existing PDF file one may achieve:

 - Modifying specific pages content and properties.
 - Adding new pages to pages collection.
 - Modify some document properties (such as Bookmarks).
 - Edit interactive forms field values.
 - Add digital signatures to existing documents.

Support for forms. The feature is named 'Interactive forms' in the PDF specification.

Main scenarios to consider:

- Reading of the data in the forms.

- Writing data to the forms.


Available in R2 2017 Release

The letters are disordered after the file is exported using PdfFormatProvider.

A NullReferenceException is thrown when trying to clone the Signature property of the field.

Available in LIB Version 2018.1.312.

Although this is not a valid postscript scenario we should not throw exceptions and we should instead skip the invalid dictionary end characters.

Fix available in LIB Version 2018.1.312.

In business or enterprises there is more and more demand for PDF/A-3.

In Germany it is Zugferd for hybrid invoices, in Brazil Nota Fiscal Eletronica 2.0, in France FACTUR-X.

Also for longterm preservation it is import to support PDF/A-3.

If I would be the PM of this library this would be my number one priority!

These images are defined directly in the PDF page content stream with BI and EI operators. Currently InvalidCastException is thrown when document with such images is imported.

Available in R1 2018 SP2 release version.

This happens only in cases when the Radio flag is not set and there are multiple widgets with different "ON" state names.

Available in R1 2018 SP2 version.

Encryption Algorithm 4 is implemented for R1 2018 official release. This includes all encryptions except AES 256 which is related to Encryption Algorithm 5. For AES 256 you may vote and follow this feedback item:

Currently RadPdfProcessing allows setting standard fonts using FontsRepository static properties.

However, in RadWordsProcessing font can be set only by specifying FontFamily, FontWeight and FontStyle. As there is no way to set standard fonts this way, API users cannot benefit from using these fonts which may help them achieve smaller PDF size as standard fonts may not be embedded. The same applies to RadSpreadhProcessing as well.

According to PDF specification, the resources used for the dynamic appearance of fields are defined globally in AcroForm "DR" PDF property. However, there are some invalid documents which define these resources locally in the field node which causes exception in PdfProcessing implementation. As there are several such documents we may consider handling such scenario instead of throwing the exception.

Available in R3 2017 SP1 Official Release.

Some PDF files have an additional content added before the file header (before %PDF-1.4 for example). This additional content makes all byte offsets in the document invalid, which causes the format provider to throw an exception.

At this point, to import a similar document it should be pre-processed so the content before the version header is removed before importing it.
