Class WMFTranscoder

This class is copied from batik org.apache.batik.transcoder.wmf.tosvg.WMFTranscoder class.

It can use TranscoderInput that are either a URI or a InputStream or a Reader. The XMLReader and Document TranscoderInput types are not supported.

This transcoder can use TranscoderOutputs that are of any type except the XMLFilter type.

Corrected bugs from the original class:

• Manage images size

Exemple of use :

    WMFTranscoder transcoder = new WMFTranscoder();
    try {
       TranscoderInput wmf = new TranscoderInput(wmffile.toURL().toString());
       FileOutputStream fos = new FileOutputStream(svgFile);
       TranscoderOutput svg =
           new TranscoderOutput(new OutputStreamWriter(fos, "UTF-8"));
       transcoder.transcode(wmf, svg);
    } catch (MalformedURLException e){
       throw new TranscoderException(e);
    } catch (IOException e){
       throw new TranscoderException(e);
    }
  

Several transcoding hints are available for this transcoder :

• KEY_INPUT_WIDTH, KEY_INPUT_HEIGHT, KEY_XOFFSET, KEY_YOFFSET : this Integer values allows to set the portion of the image to transcode, defined by the width, height, and offset of this portion in Metafile units.

     transcoder.addTranscodingHint(FromWMFTranscoder.KEY_INPUT_WIDTH, new Integer(input_width));
  

     transcoder.addTranscodingHint(FromWMFTranscoder.KEY_WIDTH, new Float(width));
