Class CSBoundingBoxCollector

java.lang.Object
  de.intarsys.pdf.content.CSDeviceAdapter
      de.intarsys.pdf.content.CSShapeDevice
          de.intarsys.pdf.content.common.CSBoundingBoxCollector

All Implemented Interfaces:

ICSDevice

public class CSBoundingBoxCollector
extends CSShapeDevice

Determine the bounding box of the content streams graphic primitives.

Usage
CSBoundingBoxCollector bbCollector = new CSBoundingBoxCollector(); CSDeviceBasedInterpreter interpreter = new CSDeviceBasedInterpreter(null, bbCollector); interpreter.process(content, getResources()); if (bbCollector.getBoundingBox() != null) { ... }

ATTENTION: The CSBoundingBoxCollector does not take care of text yet !!
