Increases dpi for tesseract extraction of pdfs #281

Closed parry-do closed 5 years ago

parry-do commented 5 years ago

Tesseract recommends a minimum dpi of 300 (here) and the default pdftoppm dpi is 150. I experienced poor accuracy on some documents and increasing the dpi fixed the issue. This could be controllable by a keyword argument, but the tesseract recommended setting seems like a better default. Love this package, it's a lifesaver.

The pdf parser will get a dpi keyword with a default value of 300 in the upcoming update. Thanks for the PR!
