remove GIMP dependency #22

Open mgiraldo opened 9 years ago

Remove dependency on GIMP for image thresholding/brightness-contrast: https://github.com/NYPL/map-vectorizer/blob/master/vectorize_map.py#L61-77

GIMP sh/could be used for determining input values in the config file: depending on the function, uses values 0→255, -128→128 or other so this needs to be taken into account.
