Members

Member	Value	Description
AlphaNumAllCapsML	8	Specifies that the image or region of interest contains only numeric symbols and capital letters in the range [A - Z]. This context is based on the GdPicture machine learning framework. To be used this context requires the alphanum_allcaps.gdpictureml file available into the specified resource folder (see GdPicture OCR.ResourcesFolder property).
HandwrittenNumericBoxML	7	Specifies that the image or region of interest contains adjacent cells where each cell contains a single handwritten digit. This context is based on the GdPicture machine learning framework. To be used this context requires the hw_digits_boxes.gdpictureml file available into the specified resource folder (see GdPicture OCR.ResourcesFolder property).
MICRLineCMC7	5	Specifies that the image or region of interest contains a special magnetic ink character recognition code zone (MICR), using MICR font.
MICRLineE13B	4	Specifies that the image or region of interest contains a special magnetic ink character recognition code zone (MICR), using E13B font.
MRZ	3	Specifies that the image or region of interest contains a special machine-readable zone (MRZ). To be used this context requires the ocrb.traineddata file available into the specified resource folder (see GdPicture OCR.ResourcesFolder property).
None	0	Specifies no special context.
NumericLineML	6	Specifies that the image or region of interest contains a line having only numeric symbols. This context is based on the GdPicture machine learning framework. To be used this context requires the digits.gdpictureml file available into the specified resource folder (see GdPicture OCR.ResourcesFolder property).
OneOrTwoNumerics	1	Specifies that the image or region of interest contains one or two numeric symbols which must be decoded. To be used this context requires the sp1.traineddata file available into the specified resource folder (see GdPicture OCR.ResourcesFolder property).
SingleLineNumerics	2	Specifies that the image or region of interest contains a line having only numeric symbols. To be used this context requires the sp1.traineddata file available into the specified resource folder (see GdPicture OCR.ResourcesFolder property).
