ROIContourDescriptor

public ROIContourDescriptor()

Method Detail

getUnit

public java.lang.String getUnit(Sequence sequence)

Description copied from class: ROIDescriptor

Returns the unit of this descriptor (ex: "px", "mm", "µm2"...).
It can return an empty or null string (default implementation) if there is no specific unit attached to the descriptor.
Note that unit is concatenated to the name to build the title (column header) in the ROI panel.

Overrides:

getUnit in class ROIDescriptor

Parameters:

sequence - the sequence on which we want to compute the descriptor (if required) to get access to the pixel size informations and return according unit

getDescription

public java.lang.String getDescription()

Description copied from class: ROIDescriptor

Returns a single line description (used as tooltip) for this descriptor

Specified by:

getDescription in class ROIDescriptor

compute

public java.lang.Object compute(ROI roi,
                       Sequence sequence)
                         throws java.lang.UnsupportedOperationException

Description copied from class: ROIDescriptor

Computes the descriptor on the specified ROI and return the result.

Specified by:

compute in class ROIDescriptor

Parameters:

roi - the ROI on which the descriptor(s) should be computed

sequence - an optional sequence where the pixel informations can be retrieved (see ROIDescriptor.separateChannel())

Returns:

the result of this descriptor computed from the specified parameters.

Throws:

java.lang.UnsupportedOperationException - if the type of the given ROI is not supported by this descriptor, or if sequence is null while the calculation requires it

computeContour

public static double computeContour(ROI roi)

Returns the number of contour point for the specified ROI.

Parameters:

roi - the ROI on which we want to compute the number of contour point

Returns:

the number of contour point
