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)/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 blocke.printStackTrace();} catch (TranscoderException e) {// TODO Auto-generated catch blocke.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：
下面列出 maven 的pom

fop.jar 没有maven地址，需要自己放入本地
