If polygon is another stimulus instance, then the verticesĪnd location of that stimulus will be used as the polygon. Orientation convention is like a clock: 0 is vertical, and positive Precisely how this is used depends on the Blend Mode. The value should be a single float ranging 1.0 (opaque) to 0.0 Visual.TextStim(win) will be called “unnamed TextStim” in the logs. If name = None your stimulus will be called “unnamed ”, e.g. In your experiment this really helps to make sense of log files! The name of the object to be using during

#Psychopy picture size code#
I'd rather use a single line of code that just universally chances the size parameters of all the visual objects to account for the warping caused by being in a 16:9 ratio.ĮDIT: Below is an example of the stretch caused by psychopy's default to an 4:3 ratio and the appropriate image. Rather than change the size of each individual visual image object I use by the following: some_obj.size *= The task will be administered on a 1920 x 1080 monitor (i.e. I'm implementing an experiment in Psychopy 1.85.1.
