java 导出pdf去除边框_如何从PDF文件中删除所有图像/图纸,并仅在Java中留下文本？...

我在类似的情况下使用Apache PDFBox.

要更具体一点,请尝试这样的事情：

import org.apache.pdfbox.exceptions.COSVisitorException;

import org.apache.pdfbox.exceptions.CryptographyException;

import org.apache.pdfbox.exceptions.InvalidPasswordException;

import org.apache.pdfbox.pdmodel.PDDocument;

import org.apache.pdfbox.pdmodel.PDDocumentCatalog;

import org.apache.pdfbox.pdmodel.PDPage;

import org.apache.pdfbox.pdmodel.PDResources;

import java.io.IOException;

public class Main {

public static void main(String[] argv) throws COSVisitorException, InvalidPasswordException, CryptographyException, IOException {

PDDocument document = PDDocument.load("input.pdf");

if (document.isEncrypted()) {

document.decrypt("");

}

PDDocumentCatalog catalog = document.getDocumentCatalog();

for (Object pageObj : catalog.getAllPages()) {

PDPage page = (PDPage) pageObj;

PDResources resources = page.findResources();

resources.getImages().clear();

}

document.save("strippedOfImages.pdf");

}

}

它应该删除所有类型的图像(png,jpeg,…).它应该这样工作：
