[MPlayer-dev-eng] [PATCH] Fractional zoom

[Panagiotis Issaris]

Hello everybody,

This patch allows you to use fractional values for specifying a zoom. I
really wanted this because in my opinion the difference between a 2x
zoom and 3x zoom is too big. 

Thus, instead of saying "mplayer -xy 2 mayall.avi" you can now say
"mplayer -xy 1.4" or "mplayer -xy 0.01" to scale down. 

At this time MPlayer uses values greater than 8 to scale down to a
certain width specified with an absolute value. My patch enables you to
use fractions and therefore specify a relative size when scaling down.

So, before this patch:
mplayer -xy v
v={2,...,8} to scale up accordingly
v={8,...,4096} to scale to the specified absolute width keeping aspect
ratio correct

After this patch:
v={0.001, ..., 0.2, ..., 1.4, ..., 8} to scale up accordingly
v={8,...,4096} to scale to the specified absolute width keeping aspect

With friendly regards,
Takis
