Use this capability to have the Source discard blank images. The Application never sees these images during the scanning session.
TWBP_DISABLE – this must be the default state for the Source. It indicates that all images will be delivered to the Application, none of them will be discarded.
TWBP_AUTO – if this is used, then the Source will decide if an image is blank or not and discard as appropriate.
If the specified value is a positive number in the range 0 to 231–1, then this capability will use it as the byte size cutoff point to identify which images are to be discarded. If the size of the image is less than or equal to this value, then it will be discarded. If the size of the image is greater than this value, then it will be kept so that it can be transferred to the Application.
