Some of the lines that should be dashed are rendered as continuous lines.

Please implement Crypt Filter for PDFs to open RC4 (40Bit, 128Bit) and AES (128Bit,256Bit) pdf Files inside PDFViewer.

There is opportunity to further optimize the caching mechanism of the image sources, which will reduce the memory consumption. The fast scrolling in a document containing big images could lead to an OutOfMemoryException.

Available in R1 2017 Official Release Version.

Currently, when printing landscape pages the content is rotated clockwise. There has to be an option to set it to anti-clockwise.

This may allow someone to notify the users.

Provide public API for accessing document properties such us Title, Author, Subject, Keywords, Creation date, etc...

Currently, all images are decoded and preserved in RGBA format (32 bits for each pixel). However, there are files that optimize their images by preserving them with 1 bit for each pixel. In WPF we may create monochrome System.Windows.Media.ImageSource that would optimize the performance and memory consumption when rendering such images.

Available in R1 2018 Official Release Version.

A rubber stamp annotation displays text or graphics intended to look as if they were stamped on the page with a rubber stamp. When opened, it displays a pop-up window containing the text of the associated note.

When this feature is implemented it should visualize the bookmarks similarly to in the attached screenshot.

Available in R3 2018 Official Release Version.

Import documents that use this type of encryption. Currently, a handled NotSupportedEncryptionException is thrown while importing such a document and it cannot be opened in RadPdfViewer.

Available in R1 2018 Official Release version.

Bitonal image scaling algorithms which improve the readability of bitonal, black and white images. Due to the lack of colors within the palette of 1-bit black and white images, they become splotchy and distorted when zoomed in or out

RadPdfViewer partially supports CCITTFaxDecode (that is basically TIFF). There are some limitations that are not supported at this stage like EncodedByteAlign = true or Group 3, 2-D encoding.

Customers are reporting an issue when trying to copy content in an application hosted on a remote machine (there are reports using TigerVNC and Citrix).  The exception is thrown from the Clipboard class with a message: OpenClipboard failed (Exception from HRESULT: 0x800401D0 (CLIPBRD_E_CANT_OPEN)).

It seems like such a behavior could be reproduced when the clipboard is already opened by another application. Here is a discussion on the matter: https://stackoverflow.com/questions/68666/clipbrd-e-cant-open-error-when-setting-the-clipboard-from-net

Fix available in LIB Version 2018.3.1029.

The hierarchical document structure is a means to describe the PDF document structure, which is currently not supported. See 10.6.1 Structure Hierarchy on 856 page of the PDF specification for details.
This document structure is an alternative to the standard PDF structure and most non-Adobe software does not support it.

The document might have been created with Adobe software like Adobe LiveCycle Designer. Very often the document contains some fallback text in the standard PDF structure like:
"Please wait... If this message is not eventually replaced by the proper contents of the document, your PDF viewer may not be able to display this type of document."
"The document you are trying to load requires Adobe Reader 8 or higher. You may not have the Adobe Reader installed or your viewing environment may not be properly configured to use Adobe Reader. For information on how to install Adobe Reader and configure your viewing environment please see  http://www.adobe.com/go/pdf_forms_configure."
"For the best experience, open this PDF portfolio in Acrobat X, Reader X, or later."

Add built-in localization for the UI control and its tooltips. Currently they can be localized by expanding the XAML of RadPdfViewerToolBar and adding the required resources to the code.

Add UI for adding comments and ability to save them. Comments are represented in the document model as text annotations (annotations with Subtype Text). 

The rendering of images with size ~5000/6000 and BitsPerComponent=1 is time-consuming. The scenario is optimized in terms of memory but would be nice to increase the performance as well.

At the moment the AnnotationsHandler, SelectionHandler and PanHandler cannot be removed or disabled. It would be convenient for this to be possible.
