CheckmarkTrainingData Object (ICheckmarkTrainingData Interface)

CheckmarkTrainingData object (ICheckmarkTrainingData interface) in the ABBYY FineReader Engine API — Holds checkmark training information for CMT_Custom checkmarks (created by IFRPage::LearnCheckmarks); a persistent object that retains BlackThreshold and SuspiciousDistance settings.

This object contains information on checkmark training. This information is created for each checkmark block of type CMT_Custom during checkmark training using the IFRPage::LearnCheckmarks method. The information cannot be edited, but can be used for recognition of checkmarks of the same type.

This object also internally retains information about the values of the BlackThreshold and SuspiciousDistance properties of the CheckmarkBlock object for which it was saved. If you load this object as TrainingData for another checkmark block, these two properties will also be set to the same values.

For the instructions on using this object to recognize checkmarks of custom type, see Recognizing Checkmarks.

The CheckmarkTrainingData object is a persistent object. This means that the object’s current state can be written to persistent storage. Later, the object can be re-created by reading the object’s state from the persistent storage. The following methods provide persistence of the object:

Linux: SaveToFile, and LoadFromFile

Windows SaveToFile, LoadFromFile, SaveToMemory, and LoadFromMemory.
