Hi Damien,
Thank you for your update
We have checked the
ImageSharp project and found that the project provides only a limited set of features. Please verify the features supported by
ImageSharp project in below link
For example, the simple text rendering and gradient brush rendering are not feasible with this project. So, it is not feasible to use this project for slide to image conversion in ASP.NET Core platfrom.
Please let us know if you need any further assistance in this.
Thanks,
Meikandan
