At the moment stdin is supported only for OCR.
PSM_AUTO_ONLY (0) and PSM_OSD_ONLY (2) expects to read data based on filename

Just so you know, if I'm not mistaken, it worked with Tesseract 3.03 and only broke with Tesseract 3.04. It is also very handy to script around Tesseract (avoid using temporary files) (see Pyocr for instance).

@jflesch: I am currios: Why you call tesseract executable from python instead of using C-API? IMO it should be faster...

When I started working on PyOCR, it was still Tesseract 2.x. At the time, if I remember correctly, there was only a C++ API and it seemed painfully hard to use (and binding on C++ API from Python is really annoying).
Also I did fork PyOCR from an already-existing python module (python-tesseract if I recall correctly).

Good to know there is a C API now. I'll have a look, see if I can bind on it easily. Thanks for the tip :)
