Extracting text from an area with PDFbox

问题

is it possible to extract text from an area with PDFbox using just the binaries instead of having to create my own code?

回答1:

Compile and pack this simple program into a jar

import java.awt.geom.Rectangle2D;
import java.io.File;
import java.io.IOException;

import org.apache.pdfbox.pdmodel.PDDocument;
import org.apache.pdfbox.pdmodel.PDPage;
import org.apache.pdfbox.text.PDFTextStripperByArea;

public class ExtractText {

    // Usage: xxx.jar filepath page x y width height
    public static void main(String[] args) throws IOException {

        if (args.length != 6) {
            System.out.println("Help info");
            return;
        }



        // Parameters
        String filepath = args[0];

        int page = Integer.parseInt(args[1]);
        int x = Integer.parseInt(args[2]);
        int y = Integer.parseInt(args[3]);
        int width = Integer.parseInt(args[4]);
        int height = Integer.parseInt(args[5]);

        PDDocument document = PDDocument.load(new File(filepath));

        PDFTextStripperByArea textStripper = new PDFTextStripperByArea();
        Rectangle2D rect = new java.awt.geom.Rectangle2D.Float(x, y, width, height);
        textStripper.addRegion("region", rect);


        PDPage docPage = document.getPage(page);

        textStripper.extractRegions(docPage);

        String textForRegion = textStripper.getTextForRegion("region");

        System.out.println(textForRegion);
    }
}

Run it from command line, ex:

xxx.jar  filepathToPdf pageToExtract  x   y   width height

Add validation code for parameters and some usage info.

Edit

Also add the PDFbox libraries

java -cp "..." -jar xxx.jar  filepathToPdf  pageToExtract  x  y  width   height
