Quite a lot of text: Opacity can be thought of as a postprocessing
|
||
|
|
operation. Conceptually, after the element (including its descendants)
|
||
|
|
is rendered into an RGBA offscreen image, the opacity setting specifies
|
||
|
|
how to blend the offscreen rendering into the current composite rendering.
|
||
|
|
The uniform opacity setting to be applied across an entire object. Any
|
||
|
|
values outside the range 0.0 (fully transparent) to 1.0 (fully opaque)
|
||
|
|
will be clamped to this range. If the object is a container element, then
|
||
|
|
the effect is as if the contents of the container element were blended
|
||
|
|
against the current background using a mask where the value of each pixel
|
||
|
|
of the mask is the opacity value
