Does anyone have any sample code to set an images transparent color when adding to ppt?
I have observed your requirements and regret to share that requested support for setting transparent color for image is unavailable in Aspose.Slides for .NET. An issue with ID SLIDESNET-33621 has been created 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 feature will be supported.
The issues you have found earlier (filed as SLIDESNET-33621) have been fixed in this update.
