attributes
Master Form recognition attributes.
fields
Master Form processing fields.
stream
A System.IO.Stream containing the name of the Master Form image data.
Returns the created IMasterForm object.
The source code for this interface implementation class is available at <Install Directory>\Examples\DotNet\CS\AutoMasterFormsRepository.
The attributes must be provided, if it is null the method will throw an exception.
The added Master Form will have the Leadtools.Forms.Recognition.FormRecognitionProperties.Name of the attributes.
The Master Form files will be stored in Path.
The Master Form attributes file will have the name of the Master Form DiskMasterForm.Name with ".bin" extension. The Master Form fields file will have the name of the Master Form DiskMasterForm.Name with ".xml" extension. The Master Form image stream file will have the name of the Master Form DiskMasterForm.Name with ".tif" extension.
