[pygame] How to control the physical size of displayed objects?
Hello,
I'm working on a program (written by someone else) to use PyGame to
display some images for use in a psychological experiment. I am new to
PyGame.
For the experiment we need to display circles of a given physical size
(let's that the diameter must be 30mm). Currently the program seems to
do the conversion with a hardcoded value.
I wanted to know if it possible to compute this value automatically.
If I understand correctly, I need to know the physical size of the
screen and the resolution. Knowing the resolution is simple with PyGame
but how can I access the screen size?
The program should be multi-platform.
Any advice?
Thanks in advance,
Mathieu
