This function returns the video aspect ratio (width / height) of the file
loaded. It can be used to adapt the size of the emotion object in the canvas,
so the aspect won't be changed (by wrongly resizing the object). Or to crop
the video correctly, if necessary.
The described behavior can be applied like following. Consider a given
emotion object that we want to position inside an area, which we will
represent by *w* and *h*. Since we want to position this object either
stretching, or filling the entire area but overflowing the video, or just
adjust the video to fit inside the area without keeping the aspect ratio, we
must compare the video aspect ratio with the area aspect ratio::
w = 200; h = 300; # an arbitrary value which represents the area where
# the video would be placed
obj = Emotion(...)
r = w / h
vr = obj.ratio
Now, if we want to make the video fit inside the area, the following code
would do it::
if vr > r: # the video is wider than the area
vw = w
vh = w / vr
else: # the video is taller than the area
vh = h
vw = h * vr
obj.size = (vw, vh)
And for keeping the aspect ratio but making the video fill the entire area,
overflowing the content which can't fit inside it, we would do::
if vr > r: # the video is wider than the area
vh = h
vw = h * vr
else: # the video is taller than the area
vw = w
vh = w / vr
obj.size = (vw, vh)
Finally, by just resizing the video to the video area, we would have the
video stretched::
vw = w
vh = h
obj.size = (vw, vh)
.. note:: This function returns the aspect ratio that the video *should* be, but
sometimes the reported size from emotion_object_size_get() represents a
different aspect ratio. You can safely resize the video to respect the aspect
ratio returned by *this* function.
