For reading characters from graphical data, google "ocr" (and "java") (the acronym means "optical character recognition") PDFs may contain the text directly (non-graphically), which would make extraction much easier (and not require ocr).

These are the ones that can be opened and modified by Office Libre and similar programs. Again, it would help if the OP could say what he is trying to do. -- martin@ | Martin Gregorie gregorie. | Essex, UK org |

If anything found, please suggest me regarding them You could spawn a copy of Nuance Omnipage. It can OCR pdfs. You might just look for PDF --> X converters.
