firstly loading the document i have use

If you reference the Telerik.Reporting and Telerik.Documents.Flow packages, you cannot use the Telerik.Documents.Core.Fonts.Fontfamily. Reports that it exists in both the packages. Even when aliasing or fully qualifying, it reports the same message that FontWeights and FontFamily exists in both the packages.

System.InvalidOperationException: 'FixedExtensibilityManager.ImagePropertiesResolver and FixedExtensibilityManager.JpegImageConverter cannot be both null. The .NET Standard does not define APIs for decoding images. That`s why in order to export images different than Jpeg and Jpeg2000 and ImageQuality different than High you will need to reference the Telerik.Documents.ImageUtils assembly/NuGet in your project and to set its basic implementation to the ImagePropertiesResolver/JpegImageConverter property or to create a custom one inheriting the ImagePropertiesResolverBase/JpegImageConverterBase class.

I am trying to programmatically reproduce a header, and nothing I've tried will add a background color or shading.  How do you format a table in a header?

Hi,

I have: Telerik UI for ASP.NET AJAX

I test SplitDocumentPages from PDF example. from https://github.com/telerik/document-processing-sdk/blob/master/PdfProcessing/ManipulatePages/Program.cs

net.framework: 4.8

test pdf is: https://github.com/telerik/document-processing-sdk/blob/master/PdfProcessing/ManipulatePages/InputFiles/MultipageDocument.pdf

Not working well. see picture split1.pdf, only large rectangle without any data.

Please help.

Thx

Hi,

 

I have an existing xlsx file that contains graphics (drawing)

I simply open the workbook, 

When I open the result file, with release 2024.3.806, I got an error. It delete drawing parts :

Partie supprimée: /xl/drawings/drawing1.xml partie.  (Forme de dessin)

With release 2024.2.426, it works fine.

Any ideas why?
