| | const struct v4l2_rect * to); |
Arguments
r
rect to be scaled.
from
from rectangle.
to
to rectangle.
Description
This scales rectangle r horizontally by to->width / from->width and
vertically by to->height / from->height.
Typically r is a rectangle inside from and you want the rectangle as
it would appear after scaling from to to. So the resulting r will
be the scaled rectangle inside to.
