I am trying to perform an SGV image conversion to PNG, but am having some problems.

My code:

   String svg_URI_input = Paths.get("/home/ivan/Documentos/imagem/Svg2.svg").toUri().toURL().toString();
    TranscoderInput input_svg_image = new TranscoderInput(svg_URI_input);        



    OutputStream png_ostream = new FileOutputStream("/home/ivan/Documentos/imagem/tica.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();       

}

Exception:

URL data in unsupported format or corrupt

    I believe the problem is in the path of the image passed which may be with the wrong formatting or the path may be incomplete.

As told by Dener, it seems your problem is way to the file.

I tested your program and it worked with full paths, but it didn’t work with the "/home".

You can try changing the input to:

String svg_URI_input = Paths.get(System.getProperty("user.home")+"/Documentos/imagem/Svg2.svg").toUri().toURL().toString();

And the output for:

OutputStream png_ostream = new FileOutputStream(System.getProperty("user.home")+"/Documentos/imagem/tica.png");
