svg 轉換為 pdf （batik 庫+fop庫）

目标：svg 轉為的 pdf 時，pdf 裡面的線條不能是不可編輯的簡單圖檔，要是可以操作的線條

方案：Java 的 batik 庫+fop庫

提上 batik 庫的官網 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/強大個 batik 庫本身 就能讀取、建立 svg，同時 可以轉為 png jpeg。。。

但如果需要轉為 為可編輯的 pdf ，需要加入另外的庫 ，即 fop 庫。原文如下：

下面貼上代碼：

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();
        }

    }
}

           

下面貼上 涉及的 jar 包（直接下載下傳即可）：

apacheBatik.zip-其它文檔類資源-CSDN下載下傳

如果沒有積分，也可以自己去一個個下載下傳：

補充：

對于svg 内包含圖檔的情況，轉換時，情況如下：

如果圖檔是以base64 方式嵌入，是沒問題的。

如果是 url方式，轉換時會報錯，但不影響其他轉換，隻是 pdf 中沒有圖檔而已

補充：

fop.jar  沒有maven位址，需要自己放入本地
