Is overlay of images possible in Psychtoolbox?

Bugs & Features

Hi all,

I am a very new user of Psychtoolbox and I was wondering if a feature is available in the platform. I want to present some images that are overlayed (with one being in the background) and the other one being in the foreground. Is that something that is possible with Psychtoolbox?

Thank you very much in advance for your time.

Yes, you can draw image textures over each other, and if you have transparency you can use alpha blending to blend them together.
