clear()

clear(): void

Clears any map specific data, as well as the modified slices, points and bounds.

Returns

void

Defined in

packages/core/src/utilities/VoxelManager.ts:425

forEach()

forEach(callback, options): any[]

Iterates over the voxels in the VoxelManager and applies a callback function to each voxel. It can operate on IJK and LPS coordinate systems, and it can be limited to a specific region of the data if the isInObject function is provided.

For the LPS calculations, both direction and spacing should be provided.

If the boundsIJK is not provided, the iteration will be over the entire volume/data

If the VoxelManager is backed by a Map, it will only iterate over the stored values. Otherwise, it will iterate over all voxels within the specified or default bounds.

Parameters

• callback

• options = {}

• options.boundsIJK?: BoundsIJK

• options.imageData?: vtkImageData | CPUImageData

• options.isInObject?

• options.returnPoints?: boolean

createScalarVolumeVoxelManager()

static createScalarVolumeVoxelManager(__namedParameters): IVoxelManager<number> | IVoxelManager<RGB>

Creates a volume value accessor, based on a volume scalar data instance. This also works for image value accessors for single plane (k=0) accessors.

This should be deprecated in favor of the createImageVolumeVoxelManager method since that one does not need to know the number of scalar data and it creates them on the fly.

Parameters

• __namedParameters

• __namedParameters.dimensions: Point3

• __namedParameters.numberOfComponents?: number = 1

• __namedParameters.scalarData: any

Returns
