Images hosted inside multiple Form XObjects are not rendered.

Some documents cannot be printed with the PdfViewer. In this case no exception is thrown and the result file is 0 bytes. 

When opening a document with a CFF Type1 font an exception is thrown: NullReferenceException: 'Object reference not set to an instance of an object.'

When changing the device culture to RTL (e.g. Hebrew but not only) in a project targeting .NET 5 (or later), some documents are rendered incorrectly.

The image inside an XObejct is not shown in the correct position. 

 Exception when rendering a file with a lot of RenderTargetBitmap objects (Com Exception: MILERR_WIN32ERROR). It seems that we are creating this for tilling patters which are not reused and we ca reconsider our appraoch.  

The text elements in a document are positioned wrongly and are slightly offset from their expected positions.

The "scn" value is not interpreted correctly which causes graphics to be drawn differently from Adobe.

 Expose API that allows you to access the current editor.

The memory consumption is increasing each time the Document property is changed at runtime. This memory doesn't get collected by the GC. To reproduce this, the Document property changes should happen with a small time interval between them. For example, several consecutive button clicks. Also, in order for that to be presented, the RadPdfViewerNavigationPane should be used and bound to the RadPdfViewer.

The issue is not reproducible if there is enough time between the Document changes, so that the UI is properly loaded.

To avoid the memory leak, avoid using the RadPdfViewerNavigationPane.

Copy and Paste omits white spaces.

A memory leak occurs in the RadTreeView control used for the table of contents in the RadPdfViewerNavigationPane, when changing the DocumentSource of RadPdfViewer at runtime.

To work this around, you can get the RadTreeView used by RadPdfViewerNavigationPane and manually clear its internal item storage before assigning the new DocumentSource.

 

 

Some lines on attached files are to thick. Other pdf programs shows that correctly.
