Yet Another PDF OCR Tool
This is a library (tool) that makes PDF -> Text as easy as possble by doing a lot of the hard stuff for you!
You will need ImageMagick, Tesseract, and QPDF to use yapot.
Ubuntu
------
> sudo apt-get install imagemagick libmagickcore-dev
> sudo apt-get install tesseract-ocr
> sudo apt-get install qpdf
To use yapot, do the following:
> pip install yapot
Then some code:
from yapot import convert_document
success, pdf_text = convert_document('file.pdf')
if success == True:
with open('file.txt', 'w') as f:
f.write(pdf_text)
else:
print "Unable to convert PDF!"
It's that simple!
Some more advanced things you can do are set the resolution, page delineation, and tell yapot not to delete temporary files (this can be useful when debugging nasty pdf's).
success, pdf_text = yapot.convert_document(
pdf_filename = pdf_filename, # The name of the pdf file
resolution = 200, # Image DPI resolution
delete_files = True, # delete temporary files
page_delineation = '\n--------\n', # page deination text
verbose = False, # output verbosity
temp_dir = str(uuid.uuid4()), # location of temp directory to use
password = '', # password for PDF file
make_thumbs = True, # create thrumbnails for each page
thumb_size = 512, # width of thumbnail image
thumb_dir = './thumbs', # directory to place thumbnails
thumb_prefix = 'thumb_page_', # prefix for thumbnail images
)
