Class Pdf2DataExtractor

java.lang.Object

com.duallab.pdf2data.Pdf2DataExtractor

public class Pdf2DataExtractor
extends Object

Pdf2DataExtractor is a class for extracting templates and data from PDF files.

To extract templates, use parseTemplateFromPDF(String pdfFile) or parseTemplateFromXML(String xmlFile).

To perform a single data extraction, use recognize(Template template, String sourcePdf).

To perform a batch extraction, it is recommended to create an instance of Pdf2DataExctractor and then use recognize(String sourcePdf) method for each pdf file.
