I am starting by trying to add a highlight. I create the object as follows: public class HighlightAnnotationBuilder extends AnnotationBuilder { public HighlightAnnotationBuilder( PDPage page, float[][] quads ) { if ( quads != null && quads.length > 0 && quads[0].length > 0) { PDAnnotationTextMarkup highlight = new PDAnnotationTextMarkup( PDAnnotationTextMarkup.SUB_TYPE_HIGHLIGHT ); PDRectangle box = new PDRectangle(); box.setLowerLeftX( quads[0][4] ); box.setLowerLeftY( quads[0][5] ); box.setUpperRightX( quads[0][2] ); box.setUpperRightY( quads[0][3] ); highlight.setRectangle( box ); highlight.setColor( YELLOW ); highlight.setContents( " placeholder " ); highlight.setConstantOpacity( ( float ) 0.8 ); highlight.setQuadPoints( quads[0] ); highlight.setPage( page ); _annotations.add( highlight ); } } } Add add the contents of _annotations to the pdf and save it. I can parse the object from the file after closing an reopening it. The debug output looks like this: 12:52:50.738 [main] DEBUG blackboard.annotationRenderer.pdf.parser.PDFReaderTest - Annotation: org.apache.pdfbox.pdmodel.interactive.annotation.PDAnnotationTextMarkup 12:52:50.742 [main] DEBUG blackboard.annotationRenderer.pdf.parser.PDFReaderTest - Rectangle: (72.000000, 684.000000), (208.793701, 720.000000); Quads: [ 72.000000, 720.000000, 208.793701, 720.000000, 72.000000, 684.000000, 208.793701, 684.000000, ] 12:52:50.742 [main] DEBUG blackboard.annotationRenderer.pdf.parser.PDFReaderTest - Hidden? false.

I have attached the PDF and would appreciate any advice.
