A customer of mine wants to create a pptx from various other powerpoints. This all works great.
But we now would like to add the ability to change the “theme” / “background”. It comes down to another header image. That is also the only difference. I’m using the Aspose cloud API but I cannot find out how to do this.
I have observed the requirements shared by you and regret to share that at present the support for setting the slide background image or changing theme is unavailable in Aspose.Slides. An issue with ID SAASSLIDES-189 has been added as new feature request in our issue tracking system to further investigate and resolve the issue. This thread has been linked with the issue so that you may be automatically notified once the support will be available.
