Represents Highlights PDF content. While the other annotations are drawn on top of the content, the highlight annotation is behind the text it highlights. In other words, it has to be inserted at a specific place in the ContentElementsUILayer. The precise place where the highlight should be placed is described in the PDF file with the BDC, MCID and EMC operators. At the moment, we have implemented a read-only rendering for all annotation types which draws the annotions separately from the page content. In the case of Highlight, the annotation is drawn below the other content. With this implementation, depending on the PDF content, the highlight annotation might be visible or it might not be because in some cases there is geometry content below the highlighted text which hides the highlight annotation appearance. 

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

The fix will be available in next LIB release (v. 2015.1.0323).

Some glyphs are not rendered correctly - the letter are translated or become unrecognizable.

The fix will be available in our next LIB release (v. 2015.02.0706).

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.

Vertical lines with small length and big thickness are drawn as short horizontal lines with big StrokeThickess. This results in rendering them as big squares, which can hide parts of the content.

Implement import of documents containing Type 3 fonts.

Workaround for documents generated with PdfProcessing: When drawing lines using the FixedContentEditor the IsFilled graphic property should be set to false:

RadFixedDocument document = new RadFixedDocument();

Rect rect = new Rect(0, 0, 50, 50);
FixedContentEditor editor = new FixedContentEditor(document.Pages.AddPage());
editor.GraphicProperties.IsFilled = false;
editor.GraphicProperties.IsStroked = true;

editor.Position.Translate(50, 50);
editor.GraphicProperties.StrokeColor = new RgbColor(255, 0, 0);
editor.DrawText("Lines");
editor.DrawLine(rect.TopLeft, rect.TopRight);
editor.DrawLine(rect.TopRight, rect.BottomRight);
editor.DrawLine(rect.BottomRight, rect.BottomLeft);
editor.DrawLine(rect.BottomLeft, rect.TopLeft);

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

Some colors are changed due to incorrect import of some graphic state colors.

The fix will be available in our latest LIB release (v. 2015.1.0323).

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.

Some of the lines that should be dashed are rendered as continuous lines.

Currently, ICC version 2 and version 4 are not supported and these colors are rendered using alternative colorspace calculations.
