Method Detail

getTransformedROI

ROI getTransformedROI(AffineTransform at,
                      int imageIndex,
                      Rectangle imgBounds,
                      ImageReadParam params,
                      ReadType readType)

Returns a transformed ROI based on the input parameters

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

boolean isEmpty()

Checks if the provided MultiLevelROI object is empty or not

Returns:

a boolean indicating if this object is empty

getFootprint

Geometry getFootprint()

This method returns a Geometry object containing the ROI footprint or, at least, its bounding box

Returns:

a Geometry object defining ROI bounds
