Struct zng::window::FrameImageReadyArgs

pub struct FrameImageReadyArgs {
    pub timestamp: DInstant,
    pub window_id: WindowId,
    pub frame_id: FrameId,
    pub frame_image: Option<Img>,
    /* private fields */
}

FRAME_IMAGE_READY_EVENT args.

Fields

timestamp: DInstant

Instant the event happened.

window_id: WindowId

Window ID.

frame_id: FrameId

Frame that finished rendering.

This is probably the ID of frame pixels if they are requested immediately.

frame_image: Option<Img>

The frame pixels if it was requested when the frame request was sent to the view-process.

See WindowVars::frame_capture_mode for more details.

Implementations

impl FrameImageReadyArgs

pub fn new( timestamp: impl Into<DInstant>, propagation_handle: EventPropagationHandle, window_id: impl Into<WindowId>, frame_id: impl Into<FrameId>, frame_image: impl Into<Option<Img>>, ) -> FrameImageReadyArgs

New args from values that convert into the argument types.

pub fn now( window_id: impl Into<WindowId>, frame_id: impl Into<FrameId>, frame_image: impl Into<Option<Img>>, ) -> FrameImageReadyArgs

Arguments for event that happened now (INSTANT.now).
