Most PDF Viewers come with the ability to print, email, text etc the PDF that is loaded.  For example, in the default iOS PDF viewer there is a "share" icon.  When the "share" icon is tapped, multiple options and apps come up that allow users to "print", "message/text", "email" the PDF.  It would be a great feature to have in the Xamarin UI PDF Viewer.  It could just be part of the PDFViewer Toolbar options.

Provide the option to integrate the hand signature using the digital signature of the PDF document

Please add a search option to PDF Viewer.

It will be great If you can also add a thumbnail preview option to view all pages in the PDF and a page slider to help navigate user to any page in seconds.

Support for FileDocumentSource

Pdf document is not loaded when it contains Type1Font "middot" glyph.

Implement import of documents containing Type 3 fonts.

As an effect of this, characters, which are not contained in the StandardEncoding names, e.g. umlauts, are measured with incorrect glyph widths. This leads to incorrect glyph positioning in RadPdfViewer.

Expose a document loaded event

Exception is thrown when importing color with Lab colorspace

An implementation of JPXDecoder should be created to allow the decompression of data encoded using the wavelet-based JPEG2000 standard.

Currently, importing a document with non-embedded TrueType font will result in a font instance with an empty font source. Support should be added for providing custom font data of TrueType fonts during document import.

Implement functionality for visualization of comment annotations.

Implement the ability to display the pages of a document with a different orientation.

Currently when the pdf document is loaded, no further changes can be made to it.  We should provide a way (automatically or explicitly through a method) to reload the page after the pdf content is modified.

Provide a way to create a custom layer in RadPdfViewer and allow to add custom objects on top of the pdf document (in a similar way as PdfViewer for WPF).

The square annotation type displays a square on the page.

Some Image XObjects are imported but not displayed in PdfViewer.

Some Image XObjects are imported but not displayed in PdfViewer.  This behavior usually occurs when the document contains scanned images.

KeyNotFoundException exception is thrown when the platform type is MacintoshNonSymbolic and the encoding is WinAnsiEncoding.
