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.

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

They are used by the page and the XObjects drawn on it and deal with the overlaying of the colors. These groups are described on page 556 of PdfReference 1.7.

When using CTRL+Mousewheel to zoom in to a PDFViewer document, it should zoom into the point where the mouse pointer is located. Currently it just does a simple zoom of the whole document.

For example see Acrobat Reader or Google Maps.

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

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

Most PDF viewers have option (enabled by default) which allows fields to be highlighted with colors predefined in the settings. Required fields are highlighted using different color.

For example: In Adobe Acrobat Reader DC this is enabled in "Edit" -> "Preferences" -> "Forms" -> "Highlight Color" -> "Show border hover color for fields".

Currently, RadPdfViewer uses WPF DrawingContext class for drawing page elements to a Canvas.  When PDF page has many content elements (usually geometries) drawing the page may be time-consuming and freezes the UI. 

Instead, we should consider implementing another approach for rendering the content asynchronously which would improve the user experience.

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.

At this point, the Print() method allowing the customers to silently print a document uses the PrintableAreaWidth and PrintableAreaHeight properties of the print dialog, which are read-only and cannot be changed through the API. Consider changing them with PrintTicket.PageMediaSize.

We should also consider the scenario when the client needs to print a smaller PDF page on a bigger page size. For instance, A5 page to be printed on an A4 sheet without scaling the content.

Expose a button in the UI that can be used instead of Ctrl+F.

Such a button can be currently added by customizing the default toolbar. For more information, check the documentation that describes how to achieve that: https://docs.telerik.com/devtools/wpf/controls/radpdfviewer/default-ui#customizing-the-default-ui

Hi!

Please extend CreateThumbnail. It is currently defined as:

 public ImageSource CreateThumbnail(RadFixedPage page, Size thumbnailSize)

Well, it works great for thumbnails and display on screen, but for saving bitmaps it is not perfect. 

If I want to change the DPI settings when saving the bitmap it is not possible, also the Pixelformat is not settable because they are hardcoded in CreateThumbnail.

Please extend CreateThumbnail like this:

 public ImageSource CreateThumbnail(RadFixedPage page, Size thumbnailSize, PixcelFormat pixelformat, int DPIX, int DPIY)

By the way, opening up the API behind radFixedPage.LoadContent and the hole drawing/rendering complex would be even better :-)

I'm dreaming of, to be able, only drawing certain layers. Sometimes it helps to see the hole object tree of a page to understand what gets painted over one another.

Thanks!

The document will be imported with a loss of content. The reason is that ASCII85Decoder will throw an ArgumentException when the stream doesn't end with '~>'. 

Although this is invalid case according to PDF specification, other applications are handling it and the document is successfully visualized in them. We may also consider implementing workaround that handles such invalid streams.
