The width values from the widths PDF property should be taken with priority compared to the font file calculations.

Fix available in R2 2018 SP1 release version.

Usually, the entries are on neighboring rows. However, some producers introduce some extra blank rows between entries and this causes exception in RadPdfViewer implementation.

This is reproducible when the field VariableTextProperties has zero value for font size.

The file contains the following:
68.637 604.561 455.981 -107.996 re
72.237 604.561 l
S
Instead of the more usual
68.637 604.561 455.981 -107.996 re
S
72.237 604.561 l
S
Both are valid but the first seems to create a problem.

When a PDF is printed all images are omitted.

Loading page with a lot of text takes several minutes which is unacceptable. This performance issue is caused by class GlypInfoFactory, which caches the glyph information.

The Ò symbol is not found in the encoding as is rendered as a ".notdef" glyph.

Decode array for image masks with DeviceGray color space is not respected, and always the default array of [0 1] is used for visualization. When the mask is encoded with [1 0], the mask is applied inversed, making the wrong pixels transparent. This may lead to images becoming invisible.

Fix available in LIB Version 2017.3.1120.

This may result in inversed transparency issue when rendering images with ImageMask.

Fix available in LIB Version 2017.3.1120.

Currently, the implementation relies on the fact that the previous cross-reference value of a stream object is always a stream object. Instead during the cross-reference recursion, we should check on each step whether the previous cross-reference item is table or stream.

The appearance of such invisible annotation is not imported property and the viewer is trying to recalculate it in an infinite recursion which causes the StackOverflowException.

Fix available in LIB Version 2017.3.1009.

When annotations have annotation flag Print they should be visualized when printing the document. Usually, Widget annotations have such flag and currently RadPdfViewer does not print them at all.

The current implementation relies on the graphic state color to be always SolidColorBrush. However, it may be other color type and InvalidCastException is thrown. This results in missing content.

Available in LIB version 2017.1.410.

The issue is caused by memory optimization that requires loading page content only for the visible pages. 

In order to fix the issue and still benefit from the memory optimization, we are introducing setter in FixedDocumentPresenterBase VisiblePages property. Now this property needs to be set each time the visible pages are changing in custom presenter implementation. Setting VisiblePages ensures that all visible pages content will be loaded correctly.
