I come in just in time: I have developed a little test application, which
have debug and release, source code, and exe.
Here is the code that get text from images:
BOOL CTemp::GetTextFromImage(CString sFileName)
{
PIX* pix = NULL;
tesseract::TessBaseAPI Tess;
do
{
if (Tess.Init(_T("*C:\\tessdata-master\\*"), _T("eng"),
tesseract::OcrEngineMode::OEM_TESSERACT_LSTM_COMBINED))
{
m_sError.Format(_T("OCRTesseract: Could not initialize tesseract."));
break;
}
// read image
PIX* pix = pixRead(sFileName);
if (! pix)
{
m_sError.Format(_T("Cannot open input file: %s."), sFileName);
break;
}
// recognize
Tess.SetImage(pix);
}
while (FALSE);
// cleanup
pixDestroy(&pix);
Tess.Clear();
Tess.End();
return m_sError.IsEmpty();
}
Of course, you have put *tessdata-master* folder in C:
The test app has an menu item: File->Read images, and from that CFileDialog
you can select multiple image file, and you can see the state of reading in
the statusbar.
If you intend to run this project on you machine, you have modify yourself
the paths in project settings. No big deal. The project is a VS2017
project, MFC.
I run this app on few Win10 64bit machines, with the same results. I have
loaded for my tests 14 images, and after all image has been converted, the
test app took 466 MB, and after these 14 images has been loaded again, the
app took 883 MB, after I loaded again, 1307 MB, and so on ... the only way
to free RAM is to stop the app and start again ! Sad :(
