svg 转换为 pdf （batik 库+fop库）

目标：svg 转为的 pdf 时，pdf 里面的线条不能是不可编辑的简单图片，要是可以操作的线条

方案：Java 的 batik 库+fop库

提上 batik 库的官网 Apache(tm) Batik SVG Toolkit - a Java-based toolkit for applications or applets that want to use images in the Scalable Vector Graphics (SVG)

http://xmlgraphics.apache.org/batik/强大个 batik 库本身 就能读取、创建 svg，同时 可以转为 png jpeg。。。

但如果需要转为 为可编辑的 pdf ，需要加入另外的库 ，即 fop 库。原文如下：

下面贴上代码：

import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;

import org.apache.batik.transcoder.Transcoder;
import org.apache.batik.transcoder.TranscoderException;
import org.apache.batik.transcoder.TranscoderInput;
import org.apache.batik.transcoder.TranscoderOutput;
import org.apache.fop.svg.PDFTranscoder;
public class SVGToPDF {

    public static void main(String[] args) {

    	String input = "f:/a/1.svg";
    	String out = "f:/a/1.pdf";
        try {
        	long start = System.currentTimeMillis();
        	
            
            TranscoderInput transcoderInput = new TranscoderInput(
                    new FileInputStream(new File(input)));
            TranscoderOutput transcoderOutput = new TranscoderOutput(
                    new FileOutputStream(new File(out)));
            
            Transcoder transcoder = new PDFTranscoder();
            transcoder.transcode(transcoderInput, transcoderOutput);
            
            long end = System.currentTimeMillis();
            System.out.println(end-start);
        } catch (FileNotFoundException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (TranscoderException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

    }
}

           

下面贴上 涉及的 jar 包（直接下载即可）：

apacheBatik.zip-其它文档类资源-CSDN下载

如果没有积分，也可以自己去一个个下载：

补充：

对于svg 内包含图片的情况，转换时，情况如下：

如果图片是以base64 方式嵌入，是没问题的。

如果是 url方式，转换时会报错，但不影响其他转换，只是 pdf 中没有图片而已

补充：

fop.jar  没有maven地址，需要自己放入本地
