suppress the debug output info of Tesseract c++ API

[Derry Pei]

Hi all,

I am currently building my own application with Tesseract C++ API in Windows 7, and when i called recognition function:

char * text = api.GetUTF8Text();

I got the following output in the command line window:

Too many unichars in ambiguity on line XXXX

Is there any way i can turn off the debug info output?

I know i can turn it off if i'm using it in command line, 

https://code.google.com/p/tesseract-ocr/wiki/FAQ#How_can_I_supress_tesseract_info_line?

but how can i do this in my application when calling the API?  like api.setVaribles()

Thanks!

Try api.setVariable("debug_file", "tesseract.log");

Thanks, Quan

I tried that, and it doesn't seem to work. I still got that output.

I googled the "debug_file" option you mentioned and it said " file to send tprintf output to ".

But i don't know why it doesn't work the way it is supposed to here.

Did you call it after init?
