Constructor Details

VectorizeOpImage

public VectorizeOpImage(RenderedImage source,
 ROI roi,
 int band,
 List<Double> outsideValues,
 boolean insideEdges,
 boolean removeCollinear,
 double filterThreshold,
 int filterMethod)

Creates a new instance of the operator.

Parameters:

source - the source image to be vectorized

roi - an optional ROI defining the region to be vectorized

band - the source image band to examine

outsideValues - values representing "outside" areas (ie. regions that will not be vectorized); may be null or empty

insideEdges - flag controlling whether boundaries between adjacent "inside" regions should be vectorized

removeCollinear - whether to remove collinear points from polygons

filterThreshold - the area (factional pixels) below which polygons will be filtered from the output

filterMethod - filtering method used if filterThreshold > 0; must be one of VectorizeDescriptor.FILTER_MERGE_LARGEST, VectorizeDescriptor.FILTER_MERGE_RANDOM, or VectorizeDescriptor.FILTER_DELETE
