[open] Global background image possible?
Hello,
I am wondering if there is any way of setting the background of a whole experiment to be an image, or gradient of two colours, as opposed to a single colour? The reason being that I am running an experiment on an Android tablet that is more engaging and fun for children with a background image; however by placing this image upon each sketchpad of the sequence causes a long lag at the end of each trial. I'm guessing that the whole sequence could be written with in-line(?) but my coding skills are not up to that at the moment. I'm hoping that there is a relatively simple way of coding a global image background..?
Many thanks,
Alex

Hi Alex,
That's an interesting question, but the short answer is: no. The only way to achieve something close to what you want is with the
psychoback-end, by creating a stimulus at the beginning of the experiment withautoDraw=True. Like so:This will draw a
GratingStimwith every new display. However, the stimulus will be drawn last, so it will hide other stimuli with which it overlaps.See also:
