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.

RadPdfViewer can not find startxref keyword at the end of a document if the document contains many zero bytes at its end. NotSupportedException is thrown with "Startxref keyword cannot be found" message. 

Workaround: Trim the ending zero bytes before loading the document to the PdfViewer. This is currently noted in the WinForms KB article:

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.

According to the PDF specification (AdobeĀ® Portable Document Format Version 1.7):
Append a rectangle to the current path as a complete subpath, with lower-left corner (x, y) and dimensions width and height in user space.

The operation: 

x y width height re

An invalid case:

0 - 595 -842 re

This leads to an exception thrown: System.NullReferenceException: 'Object reference not set to an instance of an object.'

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

Guidelines of how to provide a custom implementation of the JPXDecode filter can be found in the Customize Rendering section of the documentation and a sample implementation can be found in the SDK examples.

Provide an event that is fired when all annotations are clicked. Currently, the AnnotationClicked event is not fired for all annotations. Perhaps we can use the same event and add a property that controls for which annotations the vent is fired.

Introduce a fallback mechanism for glyphs that cannot be found in the current font

When extracting text from a composite font the ToUnicode mapping should be used but when this mapping is missing the char codes must be mapped by constructing a secondary map from fonts ordering and registry. 

A possible workaround could be to register a TrueType font using the FontsRepository.RegisterFont() method:

FontsRepository.RegisterFont(new FontFamily(fontName), FontStyles.Normal, FontWeights.Normal, File.ReadAllBytes(pathToFont));
and then to iterate the document content and change the specific font with the registered one:
FontsRepository.TryCreateFont(new FontFamily(fontName), FontStyles.Normal, FontWeights.Normal, out FontBase font);

foreach (RadFixedPage page in document.Pages)
{
	foreach (ContentElementBase contentElement in page.Content)
	{
		if (contentElement is TextFragment textFragment)
		{
			if (textFragment.Font.Name == fontName)
			{
				textFragment.Font = font;
			}
		}
	}
}
