This interface allows a client to set a factor for the alpha values on a
|
|
surface, which can be used to offload such operations to the compositor,
|
|
which can in turn for example offload them to KMS.

Warning! The protocol described in this file is currently in the testing
|
|
phase. Backward compatible changes may be added together with the
|
|
corresponding interface version bump. Backward incompatible changes can
|
|
only be done by creating a new major version of the extension.

This interface allows the client to set a factor for the alpha values on

a surface, which can be used to offload such operations to the compositor.

The default factor is UINT32_MAX.

This object has to be destroyed before the associated wl_surface. Once the
|

wl_surface is destroyed, all request on this object will raise the

This destroys the object, and is equivalent to set_multiplier with

a value of UINT32_MAX, with the same double-buffered semantics as
|
|
set_multiplier.

<description summary="specify the alpha multiplier">
|
|
Sets the alpha multiplier for the surface. The alpha multiplier is
|
|
double-buffered state, see wl_surface.commit for details.
|
|
|
|
This factor is applied in the compositor's blending space, as an
|
|
additional step after the processing of per-pixel alpha values for the
|
|
wl_surface. The exact meaning of the factor is thus undefined, unless
|
|
the blending space is specified in a different extension.
|
|
|
|
This multiplier is applied even if the buffer attached to the
|
|
wl_surface doesn't have an alpha channel; in that case an alpha value
|
|
of one is used instead.
|
|
|
|
Zero means completely transparent, UINT32_MAX means completely opaque.
