Based on your example, though, I think this should work. If I cache the rectangle coordinates (Rectangle2D) before processing the page and then test for whether the rectangle contains each TextPosition in writeString(String text, List<TextPosition> textPositions), this might work?...have to implement to test this idea... The key from your example is to subtract the rectangle's y values from the height of the page. PDAnnotationLink's rectangle is: (lowerleftx) 69.75 : (lly)440.83 : (upperrightx)153.45 : (upry)415.38 TEXT: This is a hyperlink x: 72.024 xDirAdj: 72.024 y: 425.93 yDirAdj: 425.93 height: 5.52 heightDir: 5.52 x: 77.40048 xDirAdj: 77.40048 y: 425.93 yDirAdj: 425.93 height: 5.52 heightDir: 5.52 .... So the "This is a hyperlink" text goes from 425.93 -> 430.45 on the y axis, which now fits within the rectangle's y range of 415.38 to 440.83. Does this seem right, or did I happen to get this right on this one doc? -----Original Message----- From: Tilman Hausherr [mailto:[email protected]] Sent: Thursday, July 7, 2016 12:55 PM To: [email protected] Subject: Re: associating text with a PDActionURI? here's code that works - for some reason, I can't take the rectangle as it is, I have to flip the coordinates.
