Hi Villu Ruusmann, Do you think disabling "character spacing" will be made little easier, like setting a property or passing a value to a method, in the later versions of PDFBox? Since the method you have suggesting to change does a lot of things, I am hesitant to override it.
Please let me know. Thank you.

Like this - "H"(0.01)"e"(0.01)"l"(0.01)"l"(0.01)"o"(10.0)"W"(0.01)"o"(0.01)"r"(0.01)"d". PDFBox 0.8.0 did not honour this instruction, but PDFBox 1.0.X does. I must admit that this is annoying when dealing with small "character spacing" values (< 0.1). > Anyway, it is not that I should be able use processTextPosition method to do my job. > What I am trying to say is - if you understood my goal is - I should be able to say what the >"quality of Construction" was for "comparable sale #1" in the image I sent you before, > then may be you could tell me if there is a way to do that with PDFBox. > I looked it up from the image - the bounding box of that cell is [x=610, y=520, width=180, height=30]. You can use class PDFTextStripperByArea instead of PDFTextStripper: PDFTextStripperByArea textStripper = new PDFTextStripperByArea(); textStripper.addRegion("CS1-QoC", new Rectangle2D.Float(610, 520, 180, 30)); // Define the symbolic name and the bounding box of the field .. // Add more fields as needed textStripper.extractRegions(pdfPage); String qualityOfConstrForCompSale1 = textStripper.getTextForRegion("CS1-QoC"); // Retrieve the value of the field by the symbolic name > > I was able to do that with version 0.8.

If I'm not mistaken, then the logic which controls the processing of characters is located on lines 481-484 (as of SVN revision 908338). If you want to disable "character spacing", delete the equality expression "spacingText == 0". If you want to make it less sensitive, substitute "0" with something greater such as "0.1".
