What is the expected output? What do you see instead?
see attached image

What version of the product are you using? On what operating system?
using windows version 0.0.1

The line "import Image" at line 6 pytesser.py expects that /PIL/ is added to 
the path. However, Pillow does not have the PIL.pth file that ensures you can 
import modules like that. As such, the import line needs to be changed to "from 
PIL import Image".

What steps will reproduce the problem?

Trying to use the code that makes a whitelist for Tesseract like follows

ocr = tesseract.TessBaseAPI()
ocr.SetVariable("tessedit_char_whitelist", "0123456789;")
ocr.SetPageSegMode(tesseract.PSM_AUTO)
ocr.Init("C:\\Program Files (x86)\\Tesseract-OCR\\","eng",tesseract.OEM_DEFAULT)

What is the expected output? What do you see instead?

Intended output is to have only "0123456789;" characters be recognized when 
using the image_to_string() function.  Using code like what is above, 
image_to_string() just ignores it and grabs whatever characters it finds.

What version of the product are you using? On what operating system?

pytesseract-0.1, Python 2.7, Windows 8.1

Please provide any additional information below.

I've been trying everything people use for Tesseract-OCR, but that doesn't work 
with pytesseract.  I haven't been able to find any solution or method to 
whitelisting with the image_to_string() function anywhere, which would be 
immensely helpful in improving the accuracy of the function.

Thanks in advance for any help on the matter.

What steps will reproduce the problem?
1. When Using Tesseract version 3.01, a title line is displayed.
2.

To stop this being displayed change the line in pytesser.py

proc = subprocess.Popen(args)

to this:

proc = subprocess.Popen(args, stdout=subprocess.PIPE)

I am running python 2.4 because 2.6 gave me the same error message.  I have 
downloaded and installed PIL.  I have also placed the pytesser dependents in 
the C:\Python24\Tools\Scripts folder.  Once I got the error message the first 
time, I then also added the files to C:\Python24\Scripts just as a precaution.

What steps will reproduce the problem?
1. import pytesser
2. os.chdir([...])
3. call any pytesser function

Is it possible to let pyteaser run with Tesseract 2.01?

1. Import pytesser into a script that's on a different path
2. Try and run pytesser.image_to_string()
3.

This is how it crashes:
Traceback (most recent call last):

    startupinfo)
WindowsError: [Error 2] The system cannot find the file specified


What version of the product are you using? On what operating system?
v0.0.1

Please provide any additional information below.
The problem is that it doesn't know where to find the tesseract.exe executable 
if current working directory is not the same as that of the script (likely).  
The fix is:  in pytesser.py, add the following lines after tesseract_exe_name, 
which figure out the path:

#=========================================
if 'pytesser' in sys.modules:
   tesseract_exe_path = sys.modules['pytesser'].__path__[0]
else:
   tesseract_exe_path = os.getcwd()
tesseract_exe_name = os.path.join(tesseract_exe_path,tesseract_exe_name)
#=========================================

It's currently not possible to install pytesser via PyPI as it lacks a setup.py 
file.

pip install PyTesser==0.0.1 should allow pytesser to be installed.

Now my picture just contains digital. but pytesser often treat some digital as 
character. so I want to remove character identify, and just keep digital. How 
can I config it?

Thanks a lot~~~

Is it possible to traing pytesser like you train tesseract. And if how do
you do it?

Will it work for images containing hand written words ??

When graceful_errors is True, pytesser will now ripple arguments through to the 
call to image_to_string after the input image has been converted to a Tesseract 
compatible format.
