[closed] using python variables as arguments in the draw image function

magusvulgaris

Hi. I have a string array, and I wanna use its content as a partial path for the draw image function. I know how to do it with opensesame variable (using brackets), but how do I do it with python variables?

Thanks!

In inline_script items, you use the functions self.get() and exp.set() to get and set variables respectively. This is described here:

• http://osdoc.cogsci.nl/usage/variables-and-conditional-qifq-statements/#getting-and-setting

For example, let's say that you have a variable img with the value 'smiley', and a file called smiley.png in the file pool. You can then show smiley.png with the following script:

from openexp.canvas import canvas
my_canvas = canvas(exp) # Create canvas
img = self.get('img') # Get the variable, like [img] in the GUI
img_path = exp.get_file('%s.png' % img) # Get the full path to the image
my_canvas.image(img_path) # Draw the image on the canvas
my_canvas.show() # Show the canvas

Cheers!
