Release LIB 2021.2.531 (31/05/2021)
When there is no ToUnicode CMap, the text from the Simple Font instance should be extracted by mapping the glyph name to its corresponding charcode according to Adobe Glyph List. Additionally, the Differences array should be included in these calculations when there is custom encoding. The current implementation of RadPdfViewer makes ToString to the original char id byte value which leads to wrong characters.

"Save As" is common functionality in most of the popular PDF Viewers. It should save the currently loaded document to a file.

Workaround: Currently there is SDK demonstrating how to add such functionality: https://github.com/telerik/xaml-sdk/tree/master/PdfViewer/PdfViewerCustomSaveCommand

Available in R3 2017 Official Release Version.

This is not quite a valid PDF file scenario according to PDF file specification. However, we may try handling it in order to show the correct number of pages. When the kid is of type Pages, it should be added to the pages traversal recursion only the first time it is met.

Default RadPdfViewer presenters load image sources async which allows to render the rest PDF content faster. However, FixedDocumentSinglePagePresenter loads images syncrhonously and all page content is rendered right after all images on the page are loaded.

Setting DocumentSource throws NullReferenceException when PdfViewer is hosted in ElementHost. When setting the DocumentSource, the Application.Dispatcher is used, but in Winforms app, the Application is not instantiated. 

Steps to reproduce:
1. Host PdfViewer in ElementHost in a WinForms application
2. Set the DocumentSource property
3. Run
Expected: The document is opened
Actual: NullReferenceException is thrown

Workaround: the document could be set to the Document property of PdfViewer. Or instead hosting the PdfViewer for WPF in ElementHost, use WinForms version of the control.

By using "Auto Detect Hyperlink" functionality RadPdfViewer should detect URLs and email addresses and turn them into hyperlinks. For instance if the PDF file contains text http://www.telerik.com/ this text should become a hyperlink.

The issue is caused by memory optimization that requires loading page content only for the visible pages. 

In order to fix the issue and still benefit from the memory optimization, we are introducing setter in FixedDocumentPresenterBase VisiblePages property. Now this property needs to be set each time the visible pages are changing in custom presenter implementation. Setting VisiblePages ensures that all visible pages content will be loaded correctly.

There is a similar question in FAQ for FontForge (https://fontforge.github.io/faq.html#mingliu) where it is described that kaiu.ttf (and probably mingliu.ttf) font does not store the correct outlines and its outlines need special treatment in order to be rendered correctly. The Chinese glyphs are rendered wrong in RadPdfViewer as well. However, Adobe Reader, FoxitReader and ChromeViewer render the glyphs correctly.

Currently, the disabling of the scrolling functionalities in PdfViewer is pretty tricky. Expose an API that allows users to control this functionality easier (hiding the scroll bars, disabling horizontal and/or vertical scrolling).

A sample of how the scrolling could be completely disabled is attached to this item.

The performance of loading the thumbnails is decreased with the removing of the cache in PdfViewer. 

Possible reason is that the pages are no longer loaded asynchronously.

Steps to reproduce:
- Open the SDK with the thumbnails for PDFViewer.
- Notice that the load of the thumbnails is slow.
