Implement import of documents containing Type 3 fonts.

Loading a document that contains big images could lead to OutOfMemory exception.

Dialog for inputting the password should be implemented in order to be able to decrypt the file content.

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.

The feature was implemented for Q2 2014.

Support for images used as brush.

Available in R2 2017 Release

We have a good news for all of you who have experienced problems with the memory consumption of RadPdfViewer. We have made significant optimization of what is cached for each page when scrolling in a document.
Please have in mind that when using big images in a document the optimization may seem not so significant. This is because there is additional opportunity to further optimization of the caching mechanism for the image sources.
I have logged this additional opportunity as a different feature request. Here is a link if you would like to subscribe for status updates of that item to: Optimize the image source cache - http://feedback.telerik.com/Project/143/Feedback/Details/189305-optimize-the-image-source-cache

The fix will be available in our official release Q1 2016.

When a PDF document contains images compressed with CCITTFaxDecode with applied BlackIs1 parameter, black color is visualized as white and white as black.

The images are loaded asynchronously and when scrolling too fast, the loader might fail to load an image if it is bigger.

Add support for importing and filling interactive forms.

Interactive Forms content is visualized read-only in RadPdfViewer UI with R1 2017 Release

Available in R3 2017 Official Release Version.

This is caused by an incorrect order of applying the TextMatrix and the glyph stroking operation.

Printing document on a machine with .NET Framework 4.6 installed does not work for some documents.

Currently, an issue is opened at Microsoft Connect: "Printing with PrintDialog fails when .NET 4.6 is installed" (https://connect.microsoft.com/VisualStudio/feedback/details/1980419/printing-with-printdialog-fails-when-net-4-6-is-installed).

Workaround: In the attached project.

Provide a functionality to show one page at a time mode.

Create appropriate methods, properties and events that will allow to users to scroll the RadPdfViewer and handle the scrolling events.
Introduce API that will allow to manipulate the scroll bars.

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

Available in R3 2018 Official Release Version.

Due to excessive memory consumption when decoding images, OutOfMemoryException can be thrown when viewing documents with large images inside them. 

Workarounds: 
- Set ExtensibilityManager.MaxImageSize = null. This will skip one resizing step, and could be beneficial in documents containing few large images.
- Use 64-bit process for the client application. This allows the process to consume much more memory. Note that starting 64-bit process while debugging can be tricky, as described in this blog post: https://weblog.west-wind.com/posts/2016/Dec/19/Visual-Studio-Debugging-and-64-Bit-NET-Applications.
