Tilman, When you say the pdf doesn't contain any annotation, what do you mean?
How do you arrive at that conclusion? My own parsing of the file comes up with exactly one annotation: org.apache.pdfbox.pdmodel.interactive.annotation.PDAnnotationTextMarkup with the following quad points: [ 72.000000, 720.000000, 208.793701, 720.000000, 72.000000, 684.000000, 208.793701, 684.000000 ].

Did you assign the annotations array to the page? Or is the PDF the "before" PDF? Tilman Am 23.05.2018 um 20:31 schrieb Ted Snider: > Fingers crossed.
