Java api for charts, getLocation() is deprecated.

hi all,

I am trying to develop a plugin that shows graphical representation of data.

but in the package "com.atlassian.jira.charts", class "Chart" the "getLocation()" method which gets the file location of graph is deprecated and it is said to use "getBase64Image()" how exactly can this be done?

 

any help is much appreciated!

Thanks,

Sharath TS

to get the location of the chart in base64

 

public String imgToB64(BufferedImage paramBufferedImage,
			String paramString) {
		// TODO Auto-generated method stub
		System.out.println("param passed : "+paramBufferedImage);
		BufferedImage bi = paramBufferedImage;
		ByteArrayOutputStream out = new ByteArrayOutputStream();
		try {
			ImageIO.write(bi, "PNG", out);
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		byte[] bytes = out.toByteArray();
		String base64bytes = Base64.encode(bytes);
		String src = "data:image/png;base64," + base64bytes;
		System.out.println("The base64 : "+src);
		return src;
	}

call the method params.put("chart", imgToB64(helper.getImage,helper.getImageMapName())

 

Use org.apache.axis.encoding.Base64
