TextRecognizedEventArgs(confidence, text, words)

text	String	The text discovered.
words	String[]	An array of strings containing the words discovered.

Example:

// Instances are created by the Tesseract component when it raises the
// TextRecognized event. Handle the event to read the recognized text:
tesseract1.TextRecognized += (sender, e) =>
{
	if (e.Confidence >= 75)
	{
		label1.Text = e.Text;
		listBox1.Items.Clear();
		listBox1.Items.AddRange(e.Words);
	}
};

// Or create an instance directly, e.g. to simulate the event in a test:
var args = new TextRecognizedEventArgs(90, "Invoice 1234", new[] { "Invoice", "1234" });
