CharConfidence Property of the PlainText Object

This property returns the recognition confidence for the specified character. This is the confidence of the main (selected) recognition variant.

Confidence estimates the accuracy of a recognition variant. It should not be understood as a general recognition quality measure: the only safe use of confidence is for comparing recognition variants of the same character. The characters extracted from the source PDF file without recognition have confidence set to 55.
