Telerik report pdf export and print error on linux

[guillaume.lebel]

Hi Everyone,

I've recently upgrade telerik reporting to the last version. I'm currently using the report viewer in a .net core application on linux. Since the last version the print option and the pdf export doesn't work anymore.

On the front end i'm getting

telerik reporting The header contains invalid values at index 0: '<null>'

and on the server server side I'm getting an exception with 

telerik.Reporting.Pdf.Fonts.TrueType.FontDataProvider

I've set the appsettings to use the GDI and still have the system.drawing.common set at 6.0 for now. I never had any issues prior to this update with the same settings. Anyone had this issue before? All other export works perfectly fine, only the pdf and print options have issues.

Thank you very much,

Guillaume

I just found the bug was already reported https://feedback.telerik.com/reporting/1629675-cannot-render-reports-to-pdf-using-the-libgdiplus-library-with-r3-2023. Any one has a workaround? 

Thank you,

Guillaume

Hi Guillaume,

The issue is fixed and will be released tomorrow, November 15th, 2023 with the upcoming Service Pack.

The alternative is to use SkiaSharp with version 17.2.23.1010 on Linux.
