Struct VideoWallCommand 

pub struct VideoWallCommand {
    pub target: DeviceUid,
    pub pos_x: u16,
    pub pos_y: u16,
    pub width: u16,
    pub height: u16,
    pub raster_w: u16,
    pub raster_h: u16,
    pub op: VideoWallOp,
}

Asks one sink to crop its source to a wall window.

This replaces the sink’s window outright: unlike a V2IP device config, no field carries a validity marker, and a zero width or height is the wire spelling of “clear the wall and show the full frame” rather than “unset”.

The opcode belongs to the loadable v2ipwall module rather than MatrixOS, and a wall has no object of its own on the wire: it is a set of sinks each holding one rectangle, one frame each. It is a command with no reply, so nothing here is ever a status readback.

Fields

target: DeviceUid

The sink to act on.

pos_x: u16

Window origin, horizontal.

pos_y: u16

Window origin, vertical.

width: u16

Window width.

height: u16

Window height.

raster_w: u16

Active picture width the window was authored against, as on VideoWallWindow.

raster_h: u16

Active picture height the window was authored against.

op: VideoWallOp

What to do with the window.

Implementations

impl VideoWallCommand

pub fn has_window(&self) -> bool

Reports whether the geometry in this command is meaningful.

A revert zeroes the window and raster and the receiver ignores those bytes, so its zeros are not a clear.

pub fn is_cleared(&self) -> bool

Reports a command that clears the wall and shows the full frame.
