Reference to a windows manager service that IMAGES can use to render images.

This service must be implemented by the window implementer, the WINDOWS service implements it.

Required Methods

fn clone_boxed(&self) -> Box<dyn ImageRenderWindowsService>

Clone the service reference.

fn new_window_root( &self, node: BoxedUiNode, render_mode: RenderMode, scale_factor: Option<Factor>, ) -> Box<dyn ImageRenderWindowRoot>

Create a window root that presents the node.

fn set_parent_in_window_context(&self, parent_id: WindowId)

Set parent window for the headless render window.

fn enable_frame_capture_in_window_context(&self, mask: Option<ImageMaskMode>)

Enable frame capture for the window.

If mask is set captures only the given channel, if not set will capture the full BGRA image.

Called inside the WINDOW context for the new window.

fn open_headless_window( &self, new_window_root: Box<dyn FnOnce() -> Box<dyn ImageRenderWindowRoot> + Send>, )

Open the window.

The new_window_root is called inside the WINDOW context for the new window.

fn on_frame_image_ready(&self, update: &EventUpdate) -> Option<(WindowId, Img)>

Returns the rendered frame image if it is ready for reading.

fn close_window(&self, window_id: WindowId)

Close the window, does nothing if the window is not found.
