• Searching watermarks

The following example demonstrates how to find and remove watermark using search criteria.

   Watermarker watermarker = new Watermarker("C:\\test.some_ext");
   SizeSearchCriteria widthRange = new SizeSearchCriteria(Dimension.Width, 50, 100);
   RotateAngleSearchCriteria rotateAngle = new RotateAngleSearchCriteria(0, 45);
   TextSearchCriteria textCriteria = new TextSearchCriteria(Pattern.compile("^Test watermark$"));

   PossibleWatermarkCollection watermarks = watermarker.search(textCriteria.and(widthRange.or(rotateAngle)));
   watermarks.clear();

   watermarker.save("C:\\modified_test.some_ext");
   watermarker.close();
