Method Detail

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

needRecompute

public boolean needRecompute(ROIEvent change)

Description copied from class: ROIDescriptor

Returns true if this descriptor need to be recomputed when the specified ROI change event happen.
By default it returns true on ROI content change, override this method if a descriptor need a specific implementation.

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

getReadOnly

public static boolean getReadOnly(ROI roi)

Returns ROI read only state
