'Tree rings on gradient/transparent images

Oct 03, 2018

Hello all

Hoping someone can help please.

I have created slides using a light grey gradient rectangle shape with transparency (text placed on this). Behind the shape I place an image (bottom and sides). Looks fantastic on PPT slides but when published, the images have 'tree rings' near where the gradient/transparency starts occurring.

Anyone have suggestions on how to overcome this issue please?

Using Presenter 360 on ppt 13; published in html/flash format

Attached a snapshot image to show.

Thanks in advance.
