### Simple WMF to SVG Transcoding

Source: https://github.com/apache/xmlgraphics-batik/blob/main/batik-transcoder/src/main/java/org/apache/batik/transcoder/wmf/tosvg/package.html

Performs a basic transcoding of a WMF Metafile to SVG. The output SVG dimensions will match the Metafile's viewport dimensions in pixels. Ensure input and output file paths are correctly specified.

```java
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);
```

### WMF to SVG Transcoding using Figure Bounds

Source: https://github.com/apache/xmlgraphics-batik/blob/main/batik-transcoder/src/main/java/org/apache/batik/transcoder/wmf/tosvg/package.html

Transcodes a WMF Metafile to SVG, defining the SVG viewbox based on the bounds of the figures within the Metafile, independent of its viewport. This requires obtaining Metafile bounds using WMFHeaderProperties first.

```java
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);
```

### WMF to SVG Transcoding with Specific Width

Source: https://github.com/apache/xmlgraphics-batik/blob/main/batik-transcoder/src/main/java/org/apache/batik/transcoder/wmf/tosvg/package.html

Transcodes a WMF Metafile to SVG, setting a specific output width. The image dimensions will be adjusted proportionally to maintain aspect ratio. This is useful for controlling the final SVG size.

```java
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);
```

### Update Interactive Chart Data

Source: https://github.com/apache/xmlgraphics-batik/blob/main/documentation-sources/content/demo/demo.html

JavaScript functions to update chart bars based on user input. Ensure input values are valid numbers and non-negative.

```javascript
var chart = document.getElementById("chart");
function update() {
  updateBar("ShoeBar");
  updateBar("CarBar");
  updateBar("TravelBar");
  updateBar("ComputerBar");
}
function updateBar(name) {
  var value = Number(document.getElementById(name).value);
  if (!isNaN(value) && value >= 0) {
    chart.updateBar(name, value);
  }
}
```
