How to set tessedit_write_images in python-tesseract?

问题

I'm trying to set tessedit_write_images but can't seem to do it, i can't see the tessinput.tif anywhere

i'm doing:

import tesseract

api = tesseract.TessBaseAPI()
api.Init(".","eng",tesseract.OEM_TESSERACT_ONLY)
api.SetPageSegMode(tesseract.PSM_AUTO_OSD)
api.SetVariable("tessedit_write_images", "T")

but i've tried with "True", "1", and some more variations, doesn't seem to work at all.

Any help?

回答1:

tessedit_write_images is checked only once in Tesseract's source code (by TessBaseAPI::ProcessPage(), see here).

So you could call api.GetThresholdedImage() and save the returned image or just call api.ProcessPage().
