This property is equivalent to the ICAP_HIGHLIGHT capability. There are two ways of determining the possible values for this capability:
call the QueryCapability method with pCapability. Capability set to ICAP_HIGHLIGHT.
call the GetCapability method (MFC) or the GetCapability2 method (VB) with pCapability. Capability set to ICAP_HIGHLIGHT and the IFlags parameter set to L_LTWAIN_CAPABILITY_GETVALUES.
For more information on specific TWAIN capabilities, refer to the TWAIN 1.9 specification.
This property is updated with the driver’s current setting when the GetProperties method is called.
To update the image effect options, set this property and the other ILTImageEffects properties accessed by the ImageEffects property and call the SetProperties method.
