RE: Text extraction - Any tutorials?

[Nitin Shukla]

Thanks Patrick for the response.

I could get the Extract the text from pdf.

Apart from extracting the text from pdf, is it possible to extract the font 
information, location or position of the text layout in the pdf using pdfbox? 
Any pointers are appreciated.

Thanks.

Regards,
Nitin

Hello,

you should add in your classpath also the commons-logging-1.1.1.jar File.

To extract Text from a PDF FIle (given as inputstream) I'm using 
following method (perhaps is not the best one):

 
    private String parsePdfFile(InputStream stream) throws Exception {
        StringWriter output = new StringWriter(4096);
        PDDocument document = null;
        try {
            document = PDDocument.load(stream);
            if (document.isEncrypted()) {
                try {
                    document.decrypt("");
                } catch (Throwable e) {
                    log.warn("Could not parse PDF File since the 
document is encrypted");
                    return "";
                }
            }
            PDFTextStripper stripper = new PDFTextStripper();
            stripper.setStartPage(1);
            stripper.setEndPage(Integer.MAX_VALUE);
            stripper.writeText(document, output);
            return output.toString();
        } catch (EOFException eofe) {
            log.warn("EOF Exception parsing PDF Document");
            return "";
        } catch (Exception e) {
            log.info("Exception parsing PDF document", e);
            return "";
        } finally {
            if (document != null) {
                try {
                    document.close();
                } catch (Exception e) {
                    /* ignore */
                }
            }
        }
    }

Regards,
Patrick
