How should Vs2015 solve this problem ?
Too many Error...
It looks like the pixRead function found the file "a.png" in C: \ datas,
why does pixRead return a NULL value?
OS : Windows 10 pro
IDE tool : visual studio 2015 update 3
Teseract - ocr version link : https ://github.com/tesseract-ocr/tesseract
(Tesseract Open Source OCR Engine(main repository))

tesseract::TessBaseAPI *api = new tesseract::TessBaseAPI();
// Initialize tesseract-ocr with English, without specifying tessdata path
if (api->Init(NULL, "eng")) {
fprintf(stderr, "Could not initialize tesseract.\n");
exit(1);
}
image = pixRead("C:\\datas\\a.tif");
api->SetImage(image);
// Get OCR result
outText = api->GetUTF8Text();
printf("\n OCR output: %s \n", outText);
// Destroy used object and release memory
api->End();
delete[] outText;
pixDestroy(&image);
return 0;
}
Output:
