Hi,
I've already complie the project in Release mode and I have link all
the library, put the Additional link and preprocessor inf. on my
Visual c++ 2005 project. My code doesn't work but i don't know why?
Someone can help me
I post the debug error:

and this is the source code:
#include <baseapi.h>
#include <resultiterator.h>
#include <allheaders.h>
using namespace tesseract;
tesseract::TessBaseAPI api;
PIX *pix;
pix = pixRead("C:\\immagini\\elaborating.jpg");
api.Init(NULL, "eng");
api.SetPageSegMode(tesseract::PSM_AUTO);
api.SetImage(pix);
char* outText = api.GetUTF8Text();
int conf = api.MeanTextConf();
int offset=0;
float slope=0;
api.GetTextDirection(&offset, &slope);
/*
std::cout<<"Confidence: "<< conf<< std::endl;
std::cout<<"PARAMETRI IMMAGINE: -offset: "<<offset << " -pendenza :"
<<slope<< std::endl;
std::cout<<"Risulatato: "<<outText<<std::endl;
*/
api.Clear();
api.End();
delete outText;
pixDestroy(&pix);
