Provide a new property that specifies FileName in SaveAs command.

Add functionality for a PDF form filler that supports text auto-sizing/shrinking like Adobe:

Introduce locking a document opened in viewer.

Expose API that allows you to access the current editor. Perhaps add some events to the EditingFields class.

Add support for XFA fields

 Add support for highlight annotations

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

Introduce support for per page rotation. The result should be automatically saved as well. 

The PDF model allows actions to be defined for widgets using the optional /A entry. 

According to the PDF specification: Codes are never longer than 12 bits; therefore, entry 4095 is the last entry of the LZW table.

Add support for Trigger Events

Show the DropDownList icon when the document contains ComboBox field. This is the default behavior in adobe as well. 

I would like to be able to set a list of page numbers that will be skipped/not loaded by the PDFViewer.

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.

When a pdf/a compliant document is opened in Adobe, there is a bar saying that the document is compliant with the standard. Expose such functionality in PdfViewer as well.

The current implementation relies on valid cross-reference table offsets in the PDF documents so that PDF objects are easily found and parsed. However, a mechanism for importing documents with invalid cross-reference table offsets may be implemented.

The attached project shows how to repair such documents.

A remote go-to action is similar to an ordinary go-to action but jumps to a destination in another PDF file instead of the current file.

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