Is there any Group Class so that we can add shapes to Group and manipulate the Group dimensions
I like to share that at the moment the support for adding group shape from scratch is unavailable in Aspose.Slides. However, if there is already a group shape available in presentation slide, you can access that and can even add or remove shapes inside it like normal shapes. Please visit this thread link for your kind reference as it answers exactly the questions that you are looking for. Please share, if I may help you further in this regard.
