Purpose

The module MaskToMarkers creates a list of ml.XMarker from a mask image.

An XMarker is created for each voxel in the input image that has a gray value greater than Lower Threshold (default: 0).

Windows

Default Panel

Input Fields

input0

name: input0, type: Image

input1 (hidden)

name: input1, type: Image

Optional vector input image. Data must be of type vec3 or vecf3.

Output Fields

outputXMarkerList

name: outputXMarkerList, type: XMarkerList(MLBase)

For accessing this object via scripting, see the Scripting Reference: MLXMarkerListWrapper.

Parameter Fields

Field Index

Lower Threshold: Double

Marker Type: Enum

Mode: Enum

progress: Double

Type: Integer

Update: Trigger

Vector Mode: Enum

Visible Fields

Lower Threshold

name: lowerThreshold, type: Double, default: 0

Sets an input voxel value above which markers shall be generated.

Marker Type

name: setType, type: Enum, default: User, deprecated name: markerIDMode

Defines which value is set as type information to the generated markers.

Values:

Title	Name	Description
User	User	The Type is set to each generated marker.
Voxel Value	VoxelValue	The original voxel value is used as the type for the generated marker at that position. Floating point values are truncated to integers; see Vector Mode for a similar option that retains decimal digits.

Type

name: type, type: Integer, default: 0, deprecated name: markerID

Sets the value that is used as a type value for all markers if Marker Type is set to User.

Mode

name: updateMode, type: Enum, default: Off, deprecated name: autoCalc

Defines the update mode of the module.

Values:

Title	Name	Deprecated Name	Description
Off	Off	FALSE	The module does not react to any field change.
Auto Update	AutoUpdate	TRUE	The module computes a new marker list on any field change.
Auto Clear	AutoClear		The module clear the output marker list on any field change.

Vector Mode

name: vectorMode, type: Enum, default: Zero, deprecated name: useVectorInput

Defines how the vector component of the markers shall be initialized.

Values:

Title	Name	Deprecated Name	Description
Zero	Zero	FALSE	Initialize all vector components to zeros (default).
Voxel Value	VoxelValue		Write the voxel value into the z component. Similar to setting a marker’s type to the voxel value (see Marker Type above), but retains decimal digits of floating point input.
Vector Input	VectorInput	TRUE	Set a marker’s vector to corresponding vec3(f) value read from second input; the vector will be filled with zeros if no valid vector image is attached.

Update

name: update, type: Trigger, deprecated name: Calculate

When pressed, the module updates its output marker list.

Hidden Fields

progress

name: progress, type: Double, persistent: no
