I am trying to convert DOCX file to RTF. The DOCX file contains content controls and images.
Content controls and text inside the controls are getting removed during conversion. Images are getting removed also.
Are these featured supported? Are there any settings to make it work?

Thank you.

Thanks for your request. We have just released a new version of Aspose.Words. The main feature in Aspose.Words for .NET 5.0.0 is load and save of DOCX documents reaching its Release status. So please try using this version.
The new version of Aspose.Words is available for download from here.
Note that Full support for Content Controls will be available later, hopefully in March.
Also note that there are two different ways images and shapes can be included in OOXML documents: VML and DrawingML. VML images and shapes are supported by Aspose.Words in DOCX files. However, DrawingML is not yet supported. We are still working on DOCX import and that includes supporting DrawingML. I think full support for DrawingML will come out in March.
Best regards.
