Remarks

The image should contain one line of characters and surrounding featureless, but possibly nonuniform and/or noisy, background; there should be no strong features in the image other than the one line of characters.

The bottom of the image should be approximately parallel to the baseline of the contained line of characters. If the line of characters is severely rotated or skewed use the Execute overload that accepts a region argument.

If AngleHalfRange is greater than zero, the angle of the line will be refined. If SkewHalfRange is greater than zero, the skew of the line will be refined.
