Struct ServerLoadedImageSurface 

pub struct ServerLoadedImageSurface { /* private fields */ }

The server-side counterpart of a LoadedImageSurface: a surface whose content is a bitmap given when it is created.

Implementations

impl ServerLoadedImageSurface

pub fn new( bitmap: Option<RefCounted<SharedBitmapImpl>>, ) -> Rc<ServerLoadedImageSurface>

Creates the surface with its bitmap (None for an image that did not load). The surface holds a reference to the bitmap until it is disposed.

Trait Implementations

impl IServerCompositionSurface for ServerLoadedImageSurface

fn bitmap(&self) -> Option<Arc<SharedBitmapImpl>>

The current content of the surface.

fn changed(&self) -> &ServerCompositionSurfaceChanged

Raised when the content changed.

fn natural_size(&self) -> Option<Size>

The size of the content in device independent pixels (the natural size of WinUI’s surfaces), which a surface brush lays out; None while the surface has no content. The default is the size of the bitmap at its DPI.

fn draw(&self, canvas: &mut dyn IDrawingContextImpl, dest: Rect, opacity: f64)

Draws the whole content of the surface into dest, in the coordinates of canvas. The default draws the bitmap.

impl IServerObject for ServerLoadedImageSurface

fn dispose(&self)

Releases the object: it has been disposed on the UI thread.

fn as_surface(self: Rc<Self>) -> Option<Rc<dyn IServerCompositionSurface>>

The object as a composition surface, if it is one.

fn as_any(&self) -> &dyn Any

fn into_any_rc(self: Rc<Self>) -> Rc<dyn Any>

fn deserialize_changes_core( &self, _reader: &mut BatchStreamReader<'_>, _committed_at: Duration, )

Reads the changes of the object from a batch.

fn values_invalidated(&self)

Called after a group of values of the object changed.

fn deserialize_changes( &self, reader: &mut BatchStreamReader<'_>, committed_at: Duration, )

Applies the changes of the object from a batch.

fn as_render_resource(self: Rc<Self>) -> Option<Rc<dyn IServerRenderResource>>

The object as a render resource, if it is one.

fn as_brush(self: Rc<Self>) -> Option<Rc<dyn IBrush>>

The object as a brush, if it is a server-side brush.

fn as_pen(self: Rc<Self>) -> Option<Rc<dyn IPen>>

The object as a pen, if it is a server-side pen.

fn as_render_data_geometry( self: Rc<Self>, ) -> Option<Rc<dyn IRenderDataGeometry>>

The object as a geometry usable by render data, if it is a server-side geometry.

fn as_transform(self: Rc<Self>) -> Option<Rc<dyn ITransform>>

The object as a transform, if it is a server-side transform.

fn as_gradient_stop(self: Rc<Self>) -> Option<Rc<dyn IGradientStop>>

The object as a gradient stop, if it is a server-side gradient stop.

fn as_animated(self: Rc<Self>) -> Option<Rc<dyn IAnimatedServerObject>>

The object as an animatable object, if it is one.

fn get_props(&self, _type_id: TypeId) -> Option<&dyn Any>

The generated property block of the given type embedded in the object, if it has one. A class that embeds generated properties forwards to their find_props; composition properties locate their fields through it.
