OrientationDetectionParams Object (IOrientationDetectionParams Interface)

This object provides access to the parameters used for tuning the page orientation detection. It is passed as a parameter into the DetectOrientation method of the FRPage object. Besides, this object is passed as a subobject of the PagePreprocessingParams object into FineReader Engine processing methods.

The OrientationDetectionParams object is a persistent object. This means that the object's current state can be written to persistent storage on disk. Later, the object can be re-created by reading the object's state from persistent storage. The following methods provide persistence of the object: SaveToFile, and LoadFromFile.

Properties

Name Type Description
Application Engine, read-only Returns the Engine object.
OrientationDetectionMode OrientationDetectionModeEnum

Specifies the mode of page orientation detection.

This property is ODM_Normal by default.

ProhibitClockwiseRotation VARIANT_BOOL

Disables clockwise page rotation when selecting the page orientation.

Note: This property must not be set to TRUE if the ProhibitCounterclockwiseRotation and ProhibitUpsidedownRotation properties are set to TRUE.

This property is FALSE by default.

ProhibitCounterclockwiseRotation VARIANT_BOOL

Disables counterclockwise page rotation when selecting the page orientation.

Note: This property must not be set to TRUE if the ProhibitClockwiseRotation and ProhibitUpsidedownRotation properties are set to TRUE.

This property is FALSE by default.

ProhibitUpsidedownRotation VARIANT_BOOL

Disables upside-down page rotation when selecting the page orientation.

Note: This property must not be set to TRUE if the ProhibitClockwiseRotation and ProhibitCounterclockwiseRotation properties are set to TRUE.

This property is FALSE by default.

Methods
