如何将 SVG 转换为 png 或 jpg [英] How to convert SVG to png or jpg

问题描述

我尝试过使用蜡染.但我得到了空的 png 文件.我还包括了所有必需的罐子.

I've tried by using batik. But I'm getting empty png file. I've also included all the required jars.

我的代码是

import org.apache.batik.transcoder.image.PNGTranscoder;
import org.apache.batik.transcoder.TranscoderInput;
import org.apache.batik.transcoder.TranscoderOutput;

public class TestSVG {
    String filePath="";
    TestSVG(String filePath) throws Exception {
        this.filePath=filePath;
                createImage();
    }


    public void createImage() throws Exception{
        String svg_URI_input = new File("test.svg").toURL().toString();
            TranscoderInput input_svg_image = new TranscoderInput(svg_URI_input);        
            //Step-2: Define OutputStream to PNG Image and attach to TranscoderOutput
            OutputStream png_ostream = new FileOutputStream("chessboard.png");
            TranscoderOutput output_png_image = new TranscoderOutput(png_ostream);              
            // Step-3: Create PNGTranscoder and define hints if required
            PNGTranscoder my_converter = new PNGTranscoder();        
            // Step-4: Convert and Write output
            System.out.println("It will print");
            my_converter.transcode(input_svg_image, output_png_image);
            System.out.println("It will not print");
            png_ostream.flush();
            png_ostream.close();        
    }
}

请在代码中使用系统输出.到第 3 步，它工作正常.

Please the sysout in the code. Upto step 3 it is working fine.

推荐答案

有了你的代码，我就可以生成PNG图片了，

With your code, I can able to generate the PNG image,

import java.io.File;
import java.io.FileOutputStream;
import java.io.OutputStream;

import org.apache.batik.transcoder.TranscoderInput;
import org.apache.batik.transcoder.TranscoderOutput;
import org.apache.batik.transcoder.image.PNGTranscoder;

public class TestSVG {
    String filePath="";
    TestSVG(String filePath) throws Exception {
       this.filePath=filePath;
            createImage();
    }


    public void createImage() throws Exception{
        String svg_URI_input = new File("asf-logo.svg").toURL().toString();
        TranscoderInput input_svg_image = new TranscoderInput(svg_URI_input);        
        //Step-2: Define OutputStream to PNG Image and attach to TranscoderOutput
        OutputStream png_ostream = new FileOutputStream(filePath);
        TranscoderOutput output_png_image = new TranscoderOutput(png_ostream);              
        // Step-3: Create PNGTranscoder and define hints if required
        PNGTranscoder my_converter = new PNGTranscoder();        
        // Step-4: Convert and Write output
        System.out.println("It will print");
        my_converter.transcode(input_svg_image, output_png_image);
        System.out.println("It will not print");
        png_ostream.flush();
        png_ostream.close();        
}

public static void main(String[] args) throws Exception {
    TestSVG svg = new TestSVG("asf-logo.png");
}
}

附加 生成的 png.

Attaching generated png.
