Surface alpha modifier manager

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.

Methods:

  • destroy –

    Destroy the alpha modifier manager object

  • get_surface –
