Hi Andreas, thanks for answering. I am now loading the document as you suggested.
I will rewrite the question, since I have been doing some testing: I understand that the code in my first message should return the same result for both of the regions, since they are defined with the same parameters, but it does not. Testing it with more regions, it only retrieves the text from one: I divide a page in 4 regions and add the regions to the stripper in the following order: 1-upper left, 2-upper right, 3-lower left, 4-lower right. After calling "extractRegions" function, only the text for the third one is retrieved. If I donnot add the third region, only the text for region 2 is retrieved. I think this behaviour is strange, and it may not be the expected. In the example you suggested, 'org.apache.pdfbox.examples.util.ExtractTextByArea', only one region is defined, so maybe the tool is not intended to extract several regions at a time. Any answer will be appreciated, thanks in advance, Ismael 2009/7/21 Andreas Lehmkühler <[email protected]>: > Hi Ismael, > > first of all try to load the pdf with PDDocument doc = PDDocument.load(file). > You don't have to parse the doc on your own.
