I'm using Tesseract 5.2.0, but I've tried 4.1.1 and 3.0.2, every time with
the appropriate data files, and this problem happens every time.
I have a simple program that reads the text of a video displayed in a
pictureBox. Everything functions well, but once the program has been
running for 20 or so seconds, it crashes with the error message:
System.Runtime.InteropServices.SEHException: 'External component has thrown
an exception.'
System.Runtime.InteropServices.SEHException
HResult=0x80004005
Message=External component has thrown an exception.
Source=<Cannot evaluate the exception source>
StackTrace:
<Cannot evaluate the exception stack trace>
I have this timer with the following code inside:
private void timer1_Tick(object sender, EventArgs e)
{
img = capturearea(pic);
TesseractEngine engine = new TesseractEngine("./tessdata",
"eng", EngineMode.TesseractOnly);
Page page = engine.Process(img, PageSegMode.Auto);
textBox1.Text = page.GetText();
}
The TesseractEngine line is the one throwing the error. I've tried every
Engine Mode in all the versions I mentioned but the same thing happens.
What could be going wrong? It feels like a RAM issue, but it happens on
another PC too and they're both powerful machines.
