Convert svg image to png in java by servlet

Here, I am trying to send a SVG image to local server and in output I want to download that image in PNG / JPEG format.

While I have found some solutions but those are done by BATIK libraries, but in my Eclipse BATIK libraries are not supported , so I can't use the batik libraries.

To use ImageIO you have to add this library, it adds the support for many image formats SVG included.

You can also convert svg to png format without the use of Batik Transcoder.

BufferedImage input_image = null; 
input_image = ImageIO.read(new File("Convert_to_PNG.svg")); //read svginto input_image object
File outputfile = new File("imageio_png_output.png"); //create new outputfile object
ImageIO.write(input_image, "PNG", outputfile);

By simply using the ImageIO library. Hope this will help!

Use batik library. Below is the code. 

    import java.io.*;
    import org.apache.batik.transcoder.image.PNGTranscoder;
    import org.apache.batik.transcoder.TranscoderInput;
    import org.apache.batik.transcoder.TranscoderOutput;
    import java.nio.file.Paths;
    import java.nio.file.Path;
    public class svg2png {
        public static void main(String[] args) throws Exception {
            //Step -1: We read the input SVG document into Transcoder Input
            //We use Java NIO for this purpose
            String svg_URI_input = Paths.get("chessboard.svg").toUri().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
            my_converter.transcode(input_svg_image, output_png_image);
            // Step 5- close / flush Output Stream
            png_ostream.flush();
            png_ostream.close();        
        }
}

Hope it will help you.
