Struct wayland_protocols::viewporter::client::wp_viewport::WpViewport

pub struct WpViewport(_);

Implementations

impl WpViewport

pub fn destroy(&self)

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.

This is a destructor, you cannot send requests to this object any longer once this method is called.

pub fn set_source(&self, x: f64, y: f64, width: f64, height: f64)

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.

pub fn set_destination(&self, width: i32, height: i32)

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.
