Interface WlBufferRequests

public interface WlBufferRequests

content for a wl_surface

A buffer provides the content for a wl_surface. Buffers are created through factory interfaces such as wl_shm, wp_linux_buffer_params (from the linux-dmabuf protocol extension) or similar. It has a width and a height and can be attached to a wl_surface, but the mechanism by which a client provides and updates the contents is defined by the buffer factory interface.

Color channels are assumed to be electrical rather than optical (in other words, encoded with a transfer function) unless otherwise specified. If the buffer uses a format that has an alpha channel, the alpha channel is assumed to be premultiplied into the electrical color channel values (after transfer function encoding) unless otherwise specified.

Note, because wl_buffer objects are created from multiple independent factory interfaces, the wl_buffer interface is frozen at version 1.
