<description summary="single pixel buffer factory">
|
||
This protocol extension allows clients to create single-pixel buffers.
|
||
|
||
Compositors supporting this protocol extension should also support the
|
||
viewporter protocol extension. Clients may use viewporter to scale a
|
||
single-pixel buffer to a desired size.
|
||
|
||
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.

Create a single-pixel buffer from four 32-bit RGBA values.

Unless specified in another protocol extension, the RGBA values use

pre-multiplied alpha.

The width and height of the buffer are 1.
