time of adding image in the existing pdf some exception is throwing can you give solution on that with smple code

[Vaibhav]

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.

Hi, Vaibhav,

If you are observing this error when exporting PDF files containing unsupported images in a .NET Standard environment, you need to add a reference to the  Telerik.Documents.ImageUtils assembly/NuGet package in your project and specify either the ImagePropertiesResolver, or the JpegImageConverter  that the FixedExtensibilityManager offers.

The following Troubleshooting PdfProcessing article is quite useful on this topic.

I hope you find this information helpful. Please, let me know if there is anything else I can assist you with.
