Description copied from interface: MultiLevelROI

Returns a transformed ROI based on the input parameters

Specified by:

getTransformedROI in interface MultiLevelROI

Parameters:

at - AffineTransformation

imageIndex - Overview level used for extracting the correct image overview

imgBounds - ImageBounds to set for Raster ROIs

readType - ReadType object indicating how the image file must be read. This may be useful for raster ROIs

Returns:

a ROI object

isEmpty

public boolean isEmpty()

Description copied from interface: MultiLevelROI

Checks if the provided MultiLevelROI object is empty or not

Specified by:

isEmpty in interface MultiLevelROI

Returns:

a boolean indicating if this object is empty

getFootprint

public Geometry getFootprint()

Description copied from interface: MultiLevelROI
