Enhancement - Set OpenCV Image

[GoogleCodeExporter]

For our project we need to combine OpenCV library and tesseract python 
bindings. So it seems more effective to set OpenCV image directly to tesseract 
instead of storing it into a file and let tesseract re-read it. 

Would it be possible to integrate following changes (included in the enclosed 
patch, the diff is made towards revision 95) into the python-tesseract project? 
I tested the patched changes under Ubuntu 11.04.

I also find out that shared tesseract library no longer names tesseract_api, so 
I also edited setup.py.

Thanks for looking on my proposed enhancement! I'm using OpenCV 2.1.0 lib which 
is in the Ubuntu repositories.

Have you linked the _tesseract.so also with the OpenCV lib? I added cv as 
additional library in setup.py script, I thought it is sufficient... Perhaps it 
also needs a cxcore part 
(http://opencv.willowgarage.com/wiki/CompileOpenCVUsingLinux)?

I tried this patch and it works great. Just a note: If you are running OpenCv2, 
all the references to the string "cv.iplimage" need to be changed to 
"cv2.cv.iplimage". But other than that, it works as advertised. Thanks to the 
OP.

I am confused. Why will need to include opencv2? Why not install python-opencv 
instead?

Updated ...

Could you send me simple script on how to use your added functions/methods?

Many thanks

This is an enhancement, not a defect.
