Enum Request

pub enum Request {
    Destroy,
    SetSource {
        x: Fixed,
        y: Fixed,
        width: Fixed,
        height: Fixed,
    },
    SetDestination {
        width: i32,
        height: i32,
    },
}

Variants

Destroy

remove scaling and cropping from the surface

The associated wl_surface’s crop and scale state is removed. The change is applied on the next wl_surface.commit.

SetSource

set the source rectangle for cropping

Set the source rectangle of the associated wl_surface. See wp_viewport for the description, and relation to the wl_buffer size.

If all of x, y, width and height are -1.0, the source rectangle is unset instead. Any other set of values where width or height are zero or negative, or x or y are negative, raise the bad_value protocol error.

The crop and scale state is double-buffered state, and will be applied on the next wl_surface.commit.

Fields

x: Fixed

source rectangle x

y: Fixed

source rectangle y

width: Fixed

source rectangle width

height: Fixed

source rectangle height

SetDestination

set the surface size for scaling

Set the destination size of the associated wl_surface. See wp_viewport for the description, and relation to the wl_buffer size.

If width is -1 and height is -1, the destination size is unset instead. Any other pair of values for width and height that contains zero or negative values raises the bad_value protocol error.

The crop and scale state is double-buffered state, and will be applied on the next wl_surface.commit.

Fields

width: i32

surface width

height: i32

surface height
