Mirrored image in PDFViewer

[Martin]

Hi,

I have a problem with visualizating images, which was signed by component (SecureBlackBox).
The final document (which is signed by this component) has image, which is shown vertically mirrored in Telerik component RadPdfViewer as shown in attached file "current.png". I am currently using version 2018.2.1912.45.

In any other pdf viewer (webBrowser, acrobat reader) it looks normal. In newest version of "Demos - Telerik UI for WPF" the PDFViewer showing created pdf normally too, shown in attached file: "demo.png".

PS: I don't know, if it has anything to do with it, but it seems widget, which is connected to created PDF, is using transformation matrix (MatrixPosition) which has attribute hasInverse set on True. But it seems like the value of this matrix doesn't change anything.

I wanted to ask, if this problem was solved/patched in newer version then 2018.2 or If is there some property which is managing this kind of behaviour?

Thanks.

Best regards
Martin.

Hi Martin,

This behavior seems to be related to a known issue that is already fixed with LIB version 2018.3.1217: PdfViewer: Annotation appears turned upside down. I would like to suggest updating the binaries version in order to check if this behavior still exists with the newer version and if it is still reproducible I would like to ask you to send us the document causing this behavior. I must assure you we treat all client files in a strictly confidential manner and for testing purposes only.

As for the result in the Demos - Telerik UI for WPF you can check the demos` binaries version on the top of the window:

Hi,

thank you for your response. I will try updating the binaries version to resolve the issue. It will take some time, but I will contact you about the result after completion.

Best regards
