Exceptions

Exception	Condition
CogSecurityViolationException
CogOCRMaxSegmenterParamsException	Thrown if: the region is entirely outside the image. UseCharacterMaxWidth is true and CharacterMinWidth is greater than CharacterMaxWidth. UseCharacterMaxHeight is true and CharacterMinHeight is greater than CharacterMaxHeight. SpaceParams.SpaceMinWidth is greater than SpaceParams.SpaceMaxWidth. CharacterFramgentMaxDistanceToMainLine is less than 0.0 or greater than 1.0. CharacterFragmentMainLineMinYOverlapFrac is less than 0.0 or greater than 1.0.
CogTransformNotLinearException	Thrown if: the image contains a non-linear transform.
CogImageAllocatedException	Thrown if the image is not allocated.
CogTimeoutExpiredException	Thrown if the Timeout expired.
ArgumentNullException	Thrown if image is null.

Remarks

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

The region is specified in the selected space coordinates of the input image. The x-axis should be approximately parallel to the baseline of the contained line of characters, with its positive direction pointing along the reading direction. The skew should be the approximate value of the skew of the line of characters.

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.
