Namespaces
namespace	donner
	Top-level Donner namespace, which is split into different sub-namespaces such as donner::svg and donner::css.

Functions
bool	donner::editor::ShouldPresentCompositedPreviewForViewport (const RenderResult::CompositedPreview &preview, const Vector2i &viewportDesiredCanvas)

Function Documentation

OverlayGesturePreviewForPresentation()

std::optional< SelectTool::ActiveGesturePreview > donner::editor::OverlayGesturePreviewForPresentation ( const std::optional< SelectTool::ActiveGesturePreview > & activeGesturePreview, const std::optional< SelectTool::ActiveDragPreview > & liveDragPreview, const std::optional< SelectTool::ActiveDragPreview > & representedDragPreview )

nodiscard

Project live gesture chrome, including the selection size/angle chip, to the overlay state.

Parameters

activeGesturePreview	Live gesture preview from the select tool.
liveDragPreview	Live drag transform currently applied to the DOM.
representedDragPreview	Drag transform the overlay/content presentation represents.

OverlayRepresentedDocumentFromLiveDocument()

Transform2d donner::editor::OverlayRepresentedDocumentFromLiveDocument ( const std::optional< SelectTool::ActiveDragPreview > & liveDragPreview, const std::optional< SelectTool::ActiveDragPreview > & representedDragPreview )

nodiscard

Return the document transform that projects live drag chrome onto the represented presentation.

Parameters

liveDragPreview	Live drag transform currently applied to the DOM.
representedDragPreview	Drag transform the presented content represents.

OverlayRepresentedDragPreviewForPresentation()

std::optional< SelectTool::ActiveDragPreview > donner::editor::OverlayRepresentedDragPreviewForPresentation ( const std::optional< SelectTool::ActiveDragPreview > & activeDragPreview, const std::optional< SelectTool::ActiveDragPreview > & displayedDragPreview, bool hasPresentableActiveDragTarget )

nodiscard

Return the drag transform that overlay chrome should represent in the current presentation frame.

Parameters

activeDragPreview	Active drag transform used by the presenter when a drag target tile is available.
displayedDragPreview	Drag transform represented by the currently cached content.
hasPresentableActiveDragTarget	True when the presenter can draw a matching drag target tile this frame.

ShouldPresentCompositedPreviewForViewport()

bool donner::editor::ShouldPresentCompositedPreviewForViewport ( const RenderResult::CompositedPreview & preview, const Vector2i & viewportDesiredCanvas )

nodiscard

Return true when a composited preview may be presented against the current viewport.

Full-canvas previews may stretch across transient canvas-size changes. Split composited previews carry per-tile raster bounds, so presenting them against a different canvas epoch can flash stale high-resolution tiles in the wrong place during zoom/drag races.

Parameters

preview	Worker-produced composited preview.
viewportDesiredCanvas	Canvas size implied by the current UI-frame viewport.
