Error on doc.process() about doc2text

[remi-pr]

If I am not mistaken this is due to using OpenCV version 2.x rather than 3.0. In this case cv2.resize() interprets the third argument as a destination array rather than the interpolation method as intended. One fix, included in the pull request #13, is to use named arguments (cv2.resize(foo, bar, interpolation=cv2.INTER_AREA) on line 77). This should make the code compatible with both OpenCV versions.

The second error you are getting is probably a consequence of the first (self.image is not produced because the downscale_image call failed).

@remi-pr is correct. Merging #13 should fix part of the issue and result in increased localizability for stacktraces.
