Returns a list of Leadtools.Forms.Common.PageAlignment objects that determines the amount of shift and scaling for each page of the Form with its corresponding page in the specified Master Form.
public IList<PageAlignment> GetFormAlignment(
FormRecognitionAttributes masterAttributes,
FormRecognitionAttributes formAttributes,
FormProgressCallback formCallback,
PageProgressCallback pageCallback
)
masterAttributes
The Master Form attributes object.
formAttributes
The Form attributes object.
formCallback
Provides status on the progress of the alignment calculations at the form level (i.e. page by page). Set it to null to ignore the progress.
pageCallback
Provides status on the progress of the alignment calculations at the page level. Set it to null to ignore the progress.
A list of Leadtools.Forms.Common.PageAlignment objects that determines the amount of shift and scaling for each page of the Form with its corresponding page in the specified Master Form.
Alignment is necessary when processing forms so that data can be extracted correctly. This function returns a Leadtools.Forms.Common.PageAlignment object that aligns a LeadRect located in the Master Form to its equivalent position in the Form.
For a complete example on using the forms recognition and processing, refer to the FormRecognitionEngine example.
