Constructor Detail

SimpleDocumentBuilder

public SimpleDocumentBuilder(boolean scalableColor,
                             boolean colorLayout,
                             boolean edgeHistogram)

Creates a new SimpleDocumentBuilder using the defined descriptors. Please note that ColorLayoutImpl and ScalableColorImpl are quite fast while EdgeHistogramImplementation is quite slow.

Do not use this constructor yourself, use the DocumentBuilderFactory instead.

Parameters:

scalableColor - defines if ScalableColorImpl should be used.

colorLayout - defines if ColorLayoutImpl should be used.

edgeHistogram - defines if EdgeHistogramImplementation should be used.
