Most libraries from Telerik Document Processing are affected after you install January 9, 2018, .NET Security and Quality Rollup (KB4055002). Applications that request a fallback font or a character that is not included in the currently selected font return the following error messages:
“FileFormatException: No FontFamily element found in FontFamilyCollection that matches current OS or greater: Win7SP1”.
Inner exception originates from: CompositeFontParser
Microsoft has released an update which fixes the issue. More information about it you can find here: Description of the Security and Quality Rollup for .NET Framework 4.6, 4.6.1, 4.6.2, 4.7, and 4.7.1 for Windows 7 SP1 and Server 2008 R2 SP1 (KB 4074880).
To keep .NET 4.7.1 installed and maintain protection against vulnerabilities that are addressed by the January security updates, uninstall the January .NET Framework Security and Quality Rollup (KB 4055002), and then install the January .NET Framework Security-Only Update (KB 4054183). To do this, follow these steps:
Roll back to the previous version of .NET Framework. To do this, follow these steps:

This week's latest resources are described below.
The content of this article is updated to describe the new properties added to the TextFragment class.
Headers and Footers
The article is introduced to describe the new feature in RadSpreadProcessing - applying headers and footers when printing a document or exporting to PDF.
A new help section that explains how you could use the new RadSpreadStreamProcessing library to achieve fast export of spreadsheet documents with minimal memory usage.
I've a .NET core web-api project and I need to edit the existing pdf (like adding an image/ text) without using UI. The pdf files are stored in Azure Cloud which I can access through URI.
So, is that doable? Would appreciate if you could point me to the right Telerik libraries and any examples would be great.
I'm using Telerik UI for Blazor and have to create some PDFs (via RadFixedDocument and PdfFormatProvider). This works fine so far.
But I also have to display a preview of the Document on my blazor-generated website (server side, not WebAssembly). It doesn't matter if this is a preview of the FixedDocument or of the generated PDF.
Does a control for "Telerik UI for Blazor" exist which can display the RadFixedDocument or the PDF? Or is there a possibility to export the RadFixedDocument or the PDF to an image and I can display this image? Or is there another way for making the created Document visible for preview?
Hello! We are having an issue while using DocxFormatProvider to convert docx to RadFlowDocument. When the provider converts, it replaces all charts in the document with blank paragraphs, and we can't catch this case. (doc for example sample doc)
Not sure that this actually qualifies as a bug, but it was unexpected behavior. For unit testing I was creating an empty Workbook document and writing it to a file. It turns out, that the file is corrupt unless it has a Worksheet added to it. The XlsxFormatProvider does not issue any error and happily writes a 3k file, but Excel can't read it. Excel throws a dialog "We found a problem with some content in the 'test.xlsx'. Do you want us...". Selecting Yes eventually comes back with a "The workbook cannot be opened or repaired by Microsoft Excel because it is corrupt." message.
Simply adding a worksheet:
will allow it to create a file that Excel will handle. Again, not sure you could call this a bug, but it wasn't what I expected it to do. It might be better if the XlsxFormatProvider threw an exception for trying to write out an empty file.
At any rate, figured I throw this out there in case anyone else runs into this behavior.
I am making a catalog of pictures. During the process the user can either select on file or multiple files sorted by category.
Why would the pdf files be so much larger than the Word files? It’s usually the other way around!
I combined the individual pdf files and it became 45MB. I combined the word files and it was 37MB. I then turned the 37MB word doc into a pdf and it became 4MB. So as output from Smartview(my program) the pdf file is 45MB but generating a pdf from the word files it is 10x smaller!!!!
