java解析pdf 图片文字_Java 读取PDF中的文本和提取PDF中的矢量图形

可以使用Apache PDFBox库来读取PDF中的文本和提取PDF中的矢量图形。以下是读取PDF中文本的示例代码：

import java.io.File;
import java.io.IOException;
import org.apache.pdfbox.pdmodel.PDDocument;
import org.apache.pdfbox.text.PDFTextStripper;

public class PDFReader {

    public static void main(String[] args) throws IOException {
        File file = new File("path/to/pdf/file.pdf");
        PDDocument document = PDDocument.load(file);
        PDFTextStripper pdfStripper = new PDFTextStripper();
        String text = pdfStripper.getText(document);
        System.out.println(text);
        document.close();
    }
}

以下是提取PDF中矢量图形的示例代码：

import java.io.File;
import java.io.IOException;
import java.util.List;
import org.apache.pdfbox.pdmodel.PDDocument;
import org.apache.pdfbox.pdmodel.graphics.PDXObject;
import org.apache.pdfbox.text.PDFTextStripper;

public class PDFVectorExtractor {

    public static void main(String[] args) throws IOException {
        File file = new File("path/to/pdf/file.pdf");
        PDDocument document = PDDocument.load(file);
        PDFTextStripper pdfStripper = new PDFTextStripper();
        List<PDXObject> xObjects = pdfStripper.getXObjects(document);
        for (PDXObject xObject : xObjects) {
            if (xObject instanceof org.apache.pdfbox.pdmodel.graphics.image.PDImageXObject) {
                // Do something with the image object
            } else {
                // Do something with the vector object
            }
        }
        document.close();
    }
}
