Comments

The DTWAIN_SetOCRCapValues function sets the capabilities of an OCR engine.

The OCR Engine Engine must be selected using one of the OCR Engine Selection Functions. The capability Capability is the engine's capability that is to be set. A list of the capabilities as well as the capabilities data type can be found in the topic DTWAIN OCR Capability Constants.

The SetType determines whether the capability value that will be retrieved is the current value, default value, or all the values supported by the capability. The values of SetType can be one of the following:

SetType	Definition
DTWAIN_CAPSET	Sets the current value of the capability.
DTWAIN_CAPRESET	Sets the capability value back to the default setting.

The DTWAIN_ARRAY CapValues must be initialized and filled with the capability's value(s) to set. If the SetType is DTWAIN_CAPRESET, the capability is set to the default value

For the DTWAIN_SetOCRCapValues function to return TRUE, the following must take place:

•	The Engine must be opened.

•	The Engine supports the capability.

The DTWAIN_IsOCRCapSupported function can be used to test if the capability is supported.
