INSTALL  view on Meta::CPAN

  tesseract
    Installing tesseract can be tricky. I don't know of a rpm or debian
    package for this one. You'll very likely have to install this from
    source. Make sure you have gcc-c++ and automake installed on your
    system- id you don't know you can proceed, but if you suffer any errors,
    simple go back, install gcc-c++ and automake, and try again.

    You may be able to simply install the SVN version of tesseract this way:

       $ cd /tmp
       $ svn checkout http://tesseract-ocr.googlecode.com/svn/trunk/ tesseract-ocr
       $ cd tesseract-ocr
       $ ./runautoconf
       $ mkdir build-directory
       $ cd build-directory
       $ ../configure
       $ make
       $ make install

    For more info, see google project on ocr, they use tesseract.

INSTALL PERL MODULES
    Ideally, you could simply say:

       cpan PDF::OCR2

    And, voila- done. And potentially, this might work. If no, I suggest to
    install perl modules in following similar order..

   perl modules install order
       $ cpan PDF::API2
       $ cpan CAM::PDF
       $ cpan PDF::Burst
       $ cpan PDF::GetImages 
       $ cpan Image::OCR::Tesseract
       $ cpan PDF::OCR2

   Image::OCR::Tesseract
    If the command 'cpan Image::OCR::Tesseract' fails.. You will need to
    download the package and install manually from distro.

       $ cd /tmp
       $ wget http://search.cpan.org/src/LEOCHARRE/Image-OCR-Tesseract-1.22/
       $ tar -xvf Image-OCR-T(tab completion)
       $ cd Image-OCR-T(tab completion)
       $ perl Makefile.PL # or you can do perl t/00(tab completion)

    This will check for image libraries and ocr engine. You will need to
    have already installed imagemagick and tesseract, as mentioned in this
    document.

    Make sure you are getting the latest version of Image::OCR::Tesseract,
    the above example is for version 1.22. I update frequently- so make
    sure. You can search for the latest version by going to
    http://search.cpan.org and search for 'Image::OCR::Tesseract'.

    There are INSTALL.* readme files in the package Image::OCR::Tesseract
    that may want to look through.

   Image::Magick
    Should already be available ( via previously installing imagemagick ).
