Package org.apache.batik.transcoder.wmf.tosvg Description

Contains all of the interfaces for transcoding WMF Metafiles to SVG. The base class to perform the transcoding is the org.apache.batik.transcoder.wmf.tosvg.WMFTranscoder class. The WMFHeaderProperties class can be used to get size informations from a WMF Metafile without converting it.

Examples

• Simple transcoding : the dimensions of the SVG output will be the same (in pixels) as the viewport dimensions of the Metafile

        TranscoderInput input = new TranscoderInput(inputFile.toURI().toString());
        OutputStream stream = new FileOutputStream(outputFile);
        TranscoderOutput output = new TranscoderOutput(stream);
        WMFTranscoder transcoder = new WMFTranscoder();
        transcoder.transcode(input,output);
    

• Setting the dimensions to a particular width or height : the image dimensions modification will be proportional

        TranscoderInput input = new TranscoderInput(inputFile.toURI().toString());
        OutputStream stream = new FileOutputStream(outputFile);
        TranscoderOutput output = new TranscoderOutput(stream);
        WMFTranscoder transcoder = new WMFTranscoder();
        transcoder.addTranscodingHint(WMFTranscoder.KEY_WIDTH, new Float(outputWidth));
        transcoder.transcode(input,output);
    

• Getting only the bounds of the figures in the Metafile : the SVG viewbox will be defined by the bounds of the figures in the Metafile, regardless of its viewport

        WMFHeaderProperties prop = new WMFHeaderProperties(inputFile);
        TranscoderInput input = new TranscoderInput(inputFile.toURI().toString());
        OutputStream stream = new FileOutputStream(outputFile);
        TranscoderOutput output = new TranscoderOutput(stream);
        WMFTranscoder transcoder = new WMFTranscoder();
        transcoder.addTranscodingHint(WMFTranscoder.KEY_INPUT_WIDTH, new Integer(prop.getWidthBoundsPixels()));
        transcoder.addTranscodingHint(WMFTranscoder.KEY_INPUT_HEIGHT, new Integer(prop.getHeightBoundsPixels()));
        transcoder.addTranscodingHint(WMFTranscoder.KEY_XOFFSET, new Integer(prop.getXOffset()));
        transcoder.addTranscodingHint(WMFTranscoder.KEY_YOFFSET, new Integer(prop.getYOffset())); 
        transcoder.transcode(input,output);
