blitting a Picture on the screen at a given position.

[Christophe Pallier]

Dear all,

To blit a Picture at coordinates (x, y) on a screen, I first crate a canvas with location (x,y), blit the picture on the canvas, and then blit the canvas on the screen (see the (kind of ugly) code at https://github.com/chrplr/PCBS/blob/master/expyriment/cards/cards.py)

I guess I am not doing it right and there might be a more direct way of blitting a picture than going through a canvas (?)

[Florian Krause]

Dear Christophe,

every visual stimulus takes the "position" argument, so also the Picture stimulus itself. Hence, there is no need for first plotting on a canvas.

Best,

Florian

Well, it is  a good reminder for us to include a section in the documentation that states which methods are shared amongst all visual stimuli :-)
