Hi Pravin,

I have observed your requirements and regret to share that at present there is no option to set image transparency in Aspose.Slides. Can you please share your requirements in the form a sample presentation so that we may investigate the possibility of implementation on our end by logging a new feature request.

Many Thanks,
