I want to save the raw pixel representation of my presented stimuli. To make the stimuli, I use GratingStim with the appropriate parameters. After drawing the content to the screen and flipping the window, I would like to extract the matrix representation containing the rgb values for all individual pixels. In psuedo-code something like this:
# Create the variables window = visual.window(...) grating = visual.GratingStim(...) grating.draw() window.flip() # And then something like.. image = grating.getPixelValues() # Or maybe? image = window.getPixelValues()
This is similar to PsychToolbox’ Screen(window, “GetImage”). How can one achieve this, or is it possible at all in Psychopy?
