Defined in

tools/src/tools/segmentation/LabelmapBaseTool.ts:156

---

handlesMultiTouchGestures

handlesMultiTouchGestures: boolean = false

Whether this tool implements its own handling for touch points that arrive after a gesture has already started.

When false (the default), an extra finger during an in-progress gesture releases the tool through cancel() so the gesture can re-resolve to the tool bound to the new finger count - normally pinch zoom or multi-finger scroll. See releaseToolForMultiTouchGesture.

Multi-part tools set this to true: cancelling them would discard points the user has already placed, and they instead ignore the extra finger for the duration of the gesture. Declaring it also keeps the manipulation tools reachable, since the dispatcher bypasses the interaction guard for such tools rather than clearing it.

Inherited from

BaseTool.handlesMultiTouchGestures

Defined in

tools/src/tools/base/BaseTool.ts:104

---

isDrawing?

protected optional isDrawing: boolean

Whether a draw loop is currently in progress. Declared here so the shared touch-cancellation path can reason about it; the drawing tools narrow it.

Defined in

tools/src/tools/segmentation/LabelmapBaseTool.ts:149

isPrimary: boolean = false

Primary tool - this is set to true when this tool is primary

Inherited from

---

activeCursorTool

static activeCursorTool: any

Set to the tool that is currently drawing the active cursor. This will be either primary mouse button tool if no tool is currently being directly interacted with, OR the tool that is directly interacted with. This logic ensures that there is only a single tool at a time drawing, which prevents tools not getting mouse updates from over-writing the cursor.

• If the tool bound to the primary button is a cursor drawing tool, use that tool and there is NOT a tool currently drawing directly
• If there is a tool currently drawing directly, then that tool should display a cursor EVEN if it normally doesn't have a custom cursor
• When a tool finishes drawing direct, it should stop being the active cursor tool unless it is also the primary tool

TOUCH_PROXIMITY

readonly static TOUCH_PROXIMITY: 36

Canvas-pixel radius used to hit-test annotations and handles for touch interactions. A fingertip covers far more screen than a cursor hotspot, so touch targets are much larger than BaseTool.MOUSE_PROXIMITY. Tools that need to widen an in-draw target for touch should use this rather than restating the number.

BaseTool.TOUCH_PROXIMITY

Defined in

---

TOUCH_TAP_MAX_CANVAS_DISTANCE

readonly static TOUCH_TAP_MAX_CANVAS_DISTANCE: 24

Maximum canvas-pixel distance a gesture may travel and still be counted as a tap by the touch start listener. Tools that commit a gesture on TOUCH_END need this to recognize the trailing TOUCH_TAP echo.

Inherited from

BaseTool.TOUCH_TAP_MAX_CANVAS_DISTANCE

Defined in

tools/src/tools/base/BaseTool.ts:76

---

TOUCH_TAP_TOLERANCE_MS

Methods

_cancelTouchDraw()

protected _cancelTouchDraw(element): void

Cancels an in-progress touch draw when the gesture turns out to be multi-finger (pinch zoom, multi-finger scroll). The rubber band of the scissors tools lives only in editData and is never written to the annotation state, so tearing the draw loop down and re-rendering makes it disappear without applying anything to the labelmap.

Tools whose stroke has already written voxels (BrushTool) need to roll those writes back as well and therefore override this.

Parameters

• element: HTMLDivElement

Returns

void

Defined in

tools/src/tools/segmentation/LabelmapBaseTool.ts:187

---

_historyRedoHandler()

protected _historyRedoHandler(evt): void

Parameters

• evt: any

Returns

void

Defined in

tools/src/tools/segmentation/LabelmapBaseTool.ts:209

---

_isTouchInteraction()

protected _isTouchInteraction(evt?): boolean

Whether an interaction event came in through the touch pipeline rather than the mouse pipeline.

Note this is a property of the gesture, not of the device: hybrid hardware (touchscreen laptops, tablets with a mouse attached) delivers both, so tools must branch on the event rather than on a device probe such as isMobile().

Parameters

• evt?: InteractionEventType

The interaction event, or undefined when a caller has no event to attribute (treated as not-touch).

Returns

boolean

Inherited from

BaseTool._isTouchInteraction

Defined in

tools/src/tools/base/BaseTool.ts:316

---

_setPreview()

protected _setPreview(results): void

Stores the result of a strategy as the shared preview, but only when the strategy actually set a preview up.

BrushStrategy.fill returns its initialized data for every stroke, with a preview or without one, so the raw result cannot go into previewData.preview directly. modified is the field that says a preview segment index went onto the labelmap: the preview composition sets modified to true only when both previewSegmentIndex and segmentIndex are present. addPreview uses the same test.

Keeping previewData.preview truthful is what lets every labelmap tool share one preview: any tool can then reject the preview that any other tool created.

Parameters

• results: any

Returns

void

Defined in

tools/src/tools/segmentation/LabelmapBaseTool.ts:266

---

acceptPreview()

acceptPreview(element): void

• options?

• options.acceptReject?: boolean

Returns

any

Defined in

tools/src/tools/segmentation/LabelmapBaseTool.ts:572

createMemo()

createMemo(segmentationId, segmentationVoxelManager): LabelmapMemo

Creates a labelmap memo instance, which stores the changes made to the labelmap rather than the initial state.

Parameters

• segmentationId: string

• segmentationVoxelManager: any

Returns

LabelmapMemo

Defined in

tools/src/tools/segmentation/LabelmapBaseTool.ts:295

---

doneEditMemo()

doneEditMemo(): void

This clears and edit memo storage to allow for further history functions to be called. Calls the complete function if present, and pushes the memo to the history memo stack.

This should be called when a tool has finished making a change which should be separated from future/other changes in terms of the history. Usually that means on endCallback (mouse up), but some tools also make changes on the initial creation of an object or have alternate flows and the doneEditMemo has to be called on mouse down or other initiation events to ensure that new changes are correctly recorded.

If the tool has no end callback, then the doneEditMemo is called from the pre mouse down callback. See ZoomTool for an example of this usage.

Returns

void

Inherited from

BaseTool.doneEditMemo

Defined in

tools/src/tools/base/BaseTool.ts:771

---

ensureCachedStatsTargets()

protected ensureCachedStatsTargets(data, targetIds, needsUpdate?): boolean

Ensures a cachedStats entry exists for every measurement target, so that the tool stats calculators (which iterate the cachedStats keys) compute statistics for each of them. This is what allows a single fusion viewport to compute the statistics of several display sets at once, even when no other viewport has computed them.

Parameters

• data: AnnotationData

the annotation data containing the cachedStats

• targetIds: string[]

the targets to seed (see getMeasurementTargets)

• needsUpdate?

optional test flagging an existing entry as incomplete (eg hydrated annotations missing units) and needing to be recalculated

Returns

boolean

true if any entry was added or flagged, meaning the stats need to be (re)calculated

Inherited from

BaseTool.ensureCachedStatsTargets

Defined in

tools/src/tools/base/BaseTool.ts:688

---

getActiveSegmentationData()

Defined in

tools/src/tools/segmentation/LabelmapBaseTool.ts:353

---

getMeasurementTargetCandidates()

protected getMeasurementTargetCandidates(viewport, data?): MeasurementTargetCandidate[]

Builds the list of candidate measurement targets for the given viewport: one per volume actor being displayed (including segmentation representations, which carry a representationUID and are excluded by the default filter rather than skipped here), falling back to a single candidate for the default view reference when there are none. The candidates are what the targetsFilter tool configuration chooses from - each carries the display set related parameters (display set, uid, exemplar instance and index) where they are known.

The candidate modality is taken from the display set where available - the exemplar instance or volume metadata for volume backed candidates, or the registered display set of the viewport for the fallback candidate. When the display set is unknown (eg a stack viewport using the legacy set image ids), the candidate has none of the display set fields, and filters can choose whether to include it based on that.

When the annotation already has a cachedStats entry for a candidate's volume (possibly created by another viewport with a different view reference), the existing key is reused as the targetId so statistics are shared rather than recomputed per view.

Parameters

• viewport: Viewport

• data?: AnnotationData

Returns

MeasurementTargetCandidate[]

Inherited from

BaseTool.getMeasurementTargetCandidates

Defined in

tools/src/tools/base/BaseTool.ts:498

---

getMeasurementTargets()

protected getMeasurementTargets(viewport, data?): string[]

Gets the array of targetIds the tool should compute and display measurement statistics for on the given viewport.

The targets are selected by the targetsFilter tool configuration option (see measurementTargetFilters for ready made filters). The filter receives the viewport's candidate display sets and the viewport, and returns the subset to measure.

Each returned targetId reuses an existing cachedStats key when statistics were already computed for the same volume (possibly by a different viewport), and is otherwise the view reference id of this viewport for that volume - so a single fusion viewport can seed and compute the statistics of every filtered target itself, even when no other viewport has computed them.

A configured filter's result is authoritative: when it returns no candidates (eg a PT-only filter on a CT viewport, or the default allPixelData filter when only a SEG is shown), an empty array is returned and no statistics are computed or displayed.

The deprecated isPreferredTargetId configuration is honoured before the filter, so existing configurations keep their behaviour. When neither selects anything and no filter is configured, the viewport's default view reference id is the single target.

Multi-target selection only works for volumes displayed on screen

TODO: Fix this for other fusion types on stack and also for inclusion of annotation measurements which are not currently on screen.

Parameters

• viewport: Viewport

• data?: AnnotationData

Returns

string[]

Parameters

• element?: any

Returns

ModifiedLabelmapToolOperationData

Defined in

tools/src/tools/segmentation/LabelmapBaseTool.ts:508

---

getTargetId()

protected getTargetId(viewport, data?): string

Get the target Id for the viewport which will be used to store the cached statistics scoped to that target in the annotations. For StackViewport, targetId is usually derived from the imageId. For VolumeViewport, it's derived from the volumeId.

This is the primary (first) entry of getMeasurementTargets, so it honours the targetsFilter tool configuration - configuring, for example, measurementTargetFilters.forModality('PT') makes the PT volume of a fusion viewport the target the statistics are stored/read for.

Parameters

• viewport: Viewport

viewport to get the targetId for

• data?: AnnotationData

Optional: The annotation's data object, containing cachedStats.

Returns

string

targetId, or undefined when a configured filter selects no targets for this viewport

findCachedStatsTargetId()

protected static findCachedStatsTargetId(data, referencedId): string

Finds an existing cachedStats key for the given referenced volume id, if statistics were already computed for that volume - the keys are view reference ids of the form volumeId:<volumeId>?..., so entries created by other viewports (with a different slice/orientation) still match.

Parameters

getViewportDisplaySets()

protected static getViewportDisplaySets(viewport): object[]

Resolves the display sets a viewport is displaying, when known. Viewports displaying registered display sets (see setDisplaySets on the generic viewports) resolve through the displaySetModule metadata (an IDisplaySet from @cornerstonejs/metadata) falling back to the generic viewport display set registration; legacy viewports (setStack with plain image ids) have no display set, so an empty list is returned and their candidates carry no display set fields.

Parameters

isSpecifiedTargetId()

static isSpecifiedTargetId(desiredVolumeId): (_viewport, __namedParameters) => any

A function generator to test if the target id is the desired one. Used for deciding which set of cached stats is appropriate to display for a given viewport.

This relies on the fact that the target id contains a substring which is the desired volume id when the target is a volume. It is also possible to use series query parameters such as /series/{seriesUID}/ to generate specific series selections within a stack viewport.

Parameters

• desiredVolumeId: string

Returns

Function

Parameters

Returns

any

Deprecated

Use the targetsFilter configuration option with measurementTargetFilters.forId instead.
