donner::editor::LayerInspectorPanel Class Reference

Stateful — owns one preview resource per active composite tile (keyed on CompositeTileSnapshot::id). OpenGL builds upload CPU thumbnail pixels into small GL textures. WebGPU builds keep backend texture snapshots alive and pass their texture views directly to ImGui, avoiding thumbnail readback. Construct and destroy on the presentation thread. More...

Detailed Description

Stateful — owns one preview resource per active composite tile (keyed on CompositeTileSnapshot::id). OpenGL builds upload CPU thumbnail pixels into small GL textures. WebGPU builds keep backend texture snapshots alive and pass their texture views directly to ImGui, avoiding thumbnail readback. Construct and destroy on the presentation thread.

render()

void donner::editor::LayerInspectorPanel::render	(	std::span< const svg::compositor::CompositorController::CompositeTileSnapshot >	tiles,
		const svg::compositor::CompositorController::StateSnapshot &	state,
		Entity	workerCompositorEntity,
		double	viewportZoom,
		double	viewportDpr,
		const Vector2i &	viewportDesiredCanvas,
		const Vector2i &	documentCanvas,
		const PresentationCoverageDiagnostics &	coverageDiagnostics,
		const svg::compositor::CompositorController::FastPathCounters &	fastPath,
		const svg::compositor::CompositorController::RenderFrameStats &	renderStats )

Render the panel into the current ImGui window. Must be called inside an ImGui::Begin(...) / End() pair AND on the GL thread.

Parameters

tiles	Unified paint-order tile list from AsyncRenderer::compositorCompositeTiles. Each entry produces one row with an inline thumbnail.
state	Compositor-wide diagnostic state (active-hints count, split-path active flag, drag-target entity, canvas size). Rendered as a state header so the operator can spot mismatches between expected and actual compositor state.
workerCompositorEntity	The worker's view of the currently-promoted entity.
viewportZoom	Editor viewport's zoom.
viewportDpr	Editor viewport's devicePixelRatio.
viewportDesiredCanvas	What the viewport's desiredCanvasSize() currently returns.
documentCanvas	What SVGDocument::canvasSize() currently returns — the committed canvas size the worker rendered at. Compare against viewportDesiredCanvas (commit pipeline) and state.canvasSize (compositor rasterize freshness).
coverageDiagnostics	Active bounded-raster and overview-infill presentation coverage.
fastPath	Fast-path counters rendered as a summary line above the table.
