Use current version 3.05.x, if possible.

 Hello,

 I'm trying to solve captcha images just for fun (or rather a challenge 
 ;-) ). I'm passing tessedit_char_whitelist and tessedit_char_blacklist 
 parameters but somehow they seem to be ignored. Perhaps I just miss 
 something.

 Warning. Invalid resolution 0 dpi. Using 70 instead.

 I'm using a windows version:

 tesseract 4.00.00alpha
  leptonica-1.74.1
   libgif 4.1.6(?) : libjpeg 8d (libjpeg-turbo 1.5.0) : libpng 1.6.20 : 
 libtiff 4.0.6 : zlib 1.2.8 : libwebp 0.4.3 : libopenjp2 2.1.0


 I'm doing it over a JPEG, could that be a problem?

 Thanks and regards,
 Lubos

I used --print-parameters with this version and I could see the parameter 
in the list included. Do you think it is not used even if listed? It's the 
same with tessedit_char_blacklist? Is there an alternative?

Thanks and regards,
Lubos

-c goes at the very end of the command, and you can combine those two 
arguments. Try this:

> tesseract threshold_problem1.jpeg stdout -c 
> tessedit_char_whitelist=ABCDEFGHIJKLMNOPQRSTUVWXYZ 
tessedit_char_blacklist=abcdefghijklmnopqrstuvwxyz
