Class: PlanarViewport

Generic GenericViewport controller.

The base class owns only shared viewport state and binding orchestration: loaded logical data, mounted renderings, view state, and per-dataset render-state forwarding. It does not know how CPU, VTK, DOM, image, volume, or media runtimes work internally.

Concrete viewport families are expected to stay thin and provide:

• a render context for their render paths
• a data provider
• a render path resolver when the default is not enough
• viewport-family-specific public APIs

Concrete render paths are expected to own:

• runtime add/remove lifecycle
• view-state interpretation for that render path
• per-dataset render-state application
• render-path-specific coordinate transforms

This split keeps migration from legacy viewports incremental without centralizing render-mode-specific behavior in the controller.

Defined in

packages/core/src/RenderingEngine/GenericViewport/Planar/PlanarViewport.ts:195

Methods

addDisplaySet()

addDisplaySet(displaySetId, options): Promise<void>

Adds a single logical planar display set.

Parameters

• displaySetId: string

Logical display set id to add.

• options: PlanarSetDataOptions = {}

Semantic orientation and binding options. The render path is inferred from the registered dataset and viewport configuration.

Returns

Promise<void>

Overrides

GenericViewport.addDisplaySet

Defined in

packages/core/src/RenderingEngine/GenericViewport/Planar/PlanarViewport.ts:405

---

addImages()

addImages(stackInputs): Promise<void>

Adds overlay images on top of the primary render path output.

Parameters

• stackInputs: IStackInput[]

Returns

Promise<void>

Defined in

packages/core/src/RenderingEngine/GenericViewport/Planar/PlanarViewport.ts:607

---

addLoadedData()

protected addLoadedData(displaySetId, data, options, shouldIgnore?): Promise<boolean>

Converts loaded logical data into a mounted rendering binding.

The binding stores render-path callbacks so future per-dataset render state, camera, transform, resize, and render requests can be routed back to the correct render-path runtime.

Parameters

• displaySetId: string

• data: LoadedData

• options: DataAddOptions

• shouldIgnore?

Returns

Promise<boolean>

Inherited from

GenericViewport.addLoadedData

Defined in

packages/core/src/RenderingEngine/GenericViewport/GenericViewport.ts:531

---

calibrateSpacing()

calibrateSpacing(imageId): void

Re-applies the calibrated pixel spacing for an image (CS-12). The native counterpart of StackViewport.calibrateSpacing.

The caller (the tools calibrateImageSpacing utility) first adds the calibration to the calibratedPixelSpacingMetadataProvider; this method then re-renders and emits IMAGE_SPACING_CALIBRATED so annotation tools invalidate their cached stats and recompute lengths against the new calibration. The native data path reads calibration fresh from getImageData() on every access (see buildPlanarImageData -> getImageDataMetadata -> buildMetadata), so there is no cached spacing to rebuild — the event + render are the whole job.

Defining this method is also what makes viewportSupportsStackCalibration return true for a native viewport, so calibrateImageSpacing routes here instead of skipping the viewport (it has no legacy setStack to fall back to).

Parameters

• imageId: string

the imageId whose calibration changed

Returns

void

Defined in

packages/core/src/RenderingEngine/GenericViewport/Planar/PlanarViewport.ts:886

---

canRenderOrientation()

canRenderOrientation(orientation, dataId?): boolean

Reports whether the viewport could render the given orientation for the current (or a specified) source data, without throwing.

Acquisition-aligned orientations are always renderable; reformatted orientations (AXIAL/SAGITTAL/CORONAL) require volume-backed data. Use this to pre-check before setOrientation() / setViewState({ orientation }) (for example to enable/disable an MPR control) instead of relying on the render-path decision service throwing on an unsupported request.

Parameters

• orientation: PlanarSetOrientationInput

The orientation to test.

• dataId?: string

Optional display set id; defaults to the active source.

Returns

boolean

true when the orientation can be rendered for the data.

Defined in

packages/core/src/RenderingEngine/GenericViewport/Planar/PlanarViewport.ts:1438

---

canvasToWorld()

canvasToWorld(canvasPos): Point3

Converts canvas-space to world-space through the resolved semantic view.

Parameters

• canvasPos: Point2

Returns

Point3

Overrides

Parameters

• actorEntryUID: string

Returns

Defined in

packages/core/src/RenderingEngine/GenericViewport/Planar/PlanarViewport.ts:2324

---

findDataIdByVolumeId()

findDataIdByVolumeId(volumeId): string

Maps a volume id to its bound display-set (data) id. Public because the tools VOI synchronizer needs it across the tools<->core boundary; it was previously reached through a structural cast against this protected member, which leaked the type contract. Planar-family specific (volume-backed), so it lives here rather than on IGenericViewport.

Parameters

• volumeId: string

Returns

string

Defined in

packages/core/src/RenderingEngine/GenericViewport/Planar/PlanarViewport.ts:2337

---

forEachBinding()

protected forEachBinding(visitor): void

---

getActors()

Point3

Defined in

packages/core/src/RenderingEngine/GenericViewport/Planar/PlanarViewport.ts:978

---

getAspectRatio()

getAspectRatio(): Point2

Returns the current axis-based stretch as [scaleX, scaleY]. The new generic viewport pipeline does not apply axis-based stretching for now, so this defaults to [1, 1]. Subclasses that support aspect-ratio stretching should override.

Returns

Point2

Inherited from

GenericViewport.getAspectRatio

Defined in

packages/core/src/RenderingEngine/GenericViewport/GenericViewport.ts:342

---

getBinding()

protected getBinding(displaySetId): ViewportDataBinding<PlanarDataPresentation>

Defined in

packages/core/src/RenderingEngine/GenericViewport/GenericViewport.ts:796

---

getCameraForEvent()

Returns the binding used for generic transform and frame-of-reference queries when a viewport family does not override the selection logic.

Returns

PlanarDataBinding

Overrides

GenericViewport.getCurrentBinding

Defined in

packages/core/src/RenderingEngine/GenericViewport/Planar/PlanarViewport.ts:1987

---

getCurrentImageId()

getCurrentImageId(viewRefSpecifier): string

Resolves the currently referenced image id from the active camera state.

Parameters

• viewRefSpecifier: ViewReferenceSpecifier = {}

Returns

string

The current image id, if one can be resolved.

Defined in

packages/core/src/RenderingEngine/GenericViewport/Planar/PlanarViewport.ts:821

---

getCurrentImageIdIndex()

getCurrentImageIdIndex(): number

Returns the current slice index for stack-like and slice-like workflows.

Returns

number

The current zero-based image index.

Defined in

packages/core/src/RenderingEngine/GenericViewport/Planar/PlanarViewport.ts:812

---

getCurrentMode()

getCurrentMode(): ViewportContentMode

Content-true classification of the bound source data for a planar viewport.

A PLANAR_NEXT viewport renders both image-id stacks and volume slices, so its content mode is derived from the active source binding's render mode (and, as a fallback, from whether a source volume id is bound) rather than from the viewport type. Returns empty when no source data is mounted.

Returns

ViewportContentMode

Overrides

GenericViewport.getCurrentMode

Defined in

packages/core/src/RenderingEngine/GenericViewport/Planar/PlanarViewport.ts:712

Defined in

packages/core/src/RenderingEngine/GenericViewport/GenericViewport.ts:648

---

getDefaultActor()

getDefaultActor(): ActorEntry

Returns the primary actor entry for the viewport.

Returns

ActorEntry

Defined in

packages/core/src/RenderingEngine/GenericViewport/Planar/PlanarViewport.ts:511

---

getDefaultImageData()

getDefaultImageData(): any

Returns the vtk image data backing the default image actor, mirroring the legacy Viewport.getDefaultImageData. Tools (e.g. the ONNX auto-pilot segmentation controller) call this directly on the viewport; native PLANAR_NEXT viewports previously threw getDefaultImageData is not a function. Returns undefined when no VTK image actor is mounted (e.g. CPU render paths).

Returns

any

Defined in

packages/core/src/RenderingEngine/GenericViewport/Planar/PlanarViewport.ts:556

---

Inherited from

GenericViewport.getDisplaySetRole

Defined in

packages/core/src/RenderingEngine/GenericViewport/GenericViewport.ts:816

---

getDisplaySets()

getDisplaySets(): object[]

Returns the display sets currently mounted on the viewport, in mount order (source binding first, then overlays). Derived from the live bindings, so it always reflects what is actually rendered - including overlays and any removeData calls. The per-entry options carry the binding role.

Returns

object[]

Inherited from

GenericViewport.getDisplaySets

Defined in

packages/core/src/RenderingEngine/GenericViewport/GenericViewport.ts:148

---

getFirstBinding()

protected getFirstBinding(): ViewportDataBinding<PlanarDataPresentation>

Returns

string

Overrides

GenericViewport.getFrameOfReferenceUID

Defined in

packages/core/src/RenderingEngine/GenericViewport/Planar/PlanarViewport.ts:1278

---

getImageActor()

getImageActor(volumeId?): vtkImageSlice

Retrieves an image actor from the viewport actors. Mirrors the legacy Viewport.getImageActor so VOI/colorbar tooling that depends on it keeps working on native PLANAR_NEXT viewports. CPU render paths (e.g. CPU stack slice rendering) have no VTK image actor, so this returns null there and callers fall back to a default range instead of throwing.

Parameters

• volumeId?: string

Optional id of the volume whose image actor is wanted.

Returns

vtkImageSlice

The image actor if present, otherwise null.

Defined in

packages/core/src/RenderingEngine/GenericViewport/Planar/PlanarViewport.ts:525

---

getImageData()

getImageData(volumeId?): unknown

Returns the active image-data object when the current render path exposes one.

Parameters

• volumeId?: string

Optional: when the viewport displays several volumes (eg a fusion viewport), return the image data of the binding showing this volume rather than of the active/default binding. Mirrors the legacy BaseVolumeViewport.getImageData(volumeId?) signature so per-target consumers (eg annotation statistics) work on both.

Returns

unknown

The image-data object, if exposed by the render path.

Defined in

packages/core/src/RenderingEngine/GenericViewport/Planar/PlanarViewport.ts:1235

---

getImageDataMetadata()

protected getMaxImageIdIndex(): number

Returns

number

Defined in

packages/core/src/RenderingEngine/GenericViewport/Planar/PlanarViewport.ts:1959

---

getNumberOfSlices()

getNumberOfSlices(): number

Returns the number of navigable slices for the current source data.

For image/stack content this is the number of image ids; for volume-slice content it is the slice count along the current view direction. This is the native equivalent of the legacy stack/volume getNumberOfSlices() and is what csUtils.jumpToSlice, scroll, and image-slice synchronizers rely on for a PLANAR_NEXT viewport (which is not a StackViewport, so it takes the slice-count navigation branch).

Returns

number

The total slice count for the active source data.

Defined in

packages/core/src/RenderingEngine/GenericViewport/Planar/PlanarViewport.ts:848

---

Returns whether a view reference is spatially compatible with this viewport.

Parameters

• viewRef: ViewReference

View reference to test.

• options: ReferenceCompatibleOptions = {}

Optional compatibility flags for the spatial check.

Returns

boolean

true when the reference can be viewed in this viewport state.

mergeDataPresentation()

protected mergeDataPresentation(displaySetId, props): PlanarDataPresentation

Merges object-like updates into the stored per-display-set render state and forwards the result immediately when mounted.

Parameters

• displaySetId: string

• props: Partial<PlanarDataPresentation>

Returns

PlanarDataPresentation

Inherited from

GenericViewport.mergeDataPresentation

Defined in

packages/core/src/RenderingEngine/GenericViewport/GenericViewport.ts:679

---

modified()

protected modified(previousCamera?): void

Pushes the current shared view state to every binding and schedules a render. Optionally fires a camera-modified event when a previous camera snapshot is provided.

Parameters

• previousCamera?: ICamera<number>

Returns

void

Overrides

GenericViewport.modified

Defined in

packages/core/src/RenderingEngine/GenericViewport/Planar/PlanarViewport.ts:1639

---

normalizeViewState()

protected normalizeViewState(viewState): PlanarViewState

Hook for subclasses to clamp or adjust view-state values before they are stored. The default implementation returns the view state unchanged.

Parameters

• viewState: PlanarViewState

Returns

PlanarViewState

Overrides

GenericViewport.normalizeViewState

Defined in

packages/core/src/RenderingEngine/GenericViewport/Planar/PlanarViewport.ts:907

---

notifyDataPresentationModified()

protected notifyDataPresentationModified(displaySetId, props): void

Emits the legacy-named presentation events (VOI_MODIFIED, COLORMAP_MODIFIED) when a per-display-set presentation update changes the VOI, invert, or colormap of a mounted dataset.

The native presentation write path previously emitted no event, so OHIF's VOI sliders, colorbar, window-level readout, and VOI/colormap synchronizers went stale after any programmatic or tool-driven setDisplaySetPresentation change on a direct PLANAR_NEXT viewport. The legacy compatibility adapter keeps emitting COLORMAP_MODIFIED through its own path (which applies presentation via setDataPresentationState directly, not through mergeDataPresentation), so this hook does not double-fire for compatibility viewports.

Parameters

• displaySetId: string

• props: Partial<PlanarDataPresentation>

Returns

void

Overrides

GenericViewport.notifyDataPresentationModified

Defined in

packages/core/src/RenderingEngine/GenericViewport/Planar/PlanarViewport.ts:752

---

resetDisplaySetPresentation()

resetDisplaySetPresentation(dataId?): void

Resets the stored per-display-set presentation (VOI / window level, colormap and inversion) back to the computed defaults for a single display set. This is the reset counterpart to setDisplaySetPresentation / getDisplaySetPresentation; the next viewport intentionally has no get/set Properties, so it does not use the legacy *Properties naming.

Clearing the stored presentation override makes the render path fall back to its defaults on the next apply (default VOI, no colormap, no inversion). "Reset View" relies on it (view/camera state is reset separately by resetViewState); without it, "Reset View" left the window level at the user-modified value on direct generic viewports.

Parameters

• dataId?: string

Optional display set id; defaults to the active source.

Returns

void

Defined in

packages/core/src/RenderingEngine/GenericViewport/Planar/PlanarViewport.ts:1528

---

resetViewState()

updateRenderingPipeline()

updateRenderingPipeline(): void

Live render-backend switch: re-runs the render-path decision for every mounted display set and remounts, in place, the ones whose effective render mode changed. The viewport instance, its id, mounted data, view state (slice/zoom/pan), per-display-set presentation, and tool annotations all survive -- addLoadedData re-applies presentation and view state to the rebuilt binding. Display sets pinned via a per-mount renderBackend re-resolve to the same path and are effectively skipped.

Called by the global setRenderBackend()/setUseCPURendering() fan-out; the rebuild is async but the hook itself is fire-and-forget by contract.

Returns

void
