Dear all,
Does anybody know how to write a graphics object to a jpeg file? I
already tried almost everything but still with no result. The code
beneath is what I think should work, but if I run it, I only get a black
image of 300 by 300. Can anybody tell me what I'm doing wrong?
* variable dist is some distance
* sLogo is not a null object, I can visualise it inside a JFrame object
code:
{
DistributionLogo sLogo = new DistributionLogo();
TextLogoPainter logoPainter = new TextLogoPainter();
sLogo.setLogoPainter(logoPainter);
sLogo.setStyle(new DNAStyle());
sLogo.setDistribution(dist);
BufferedImage bufIm = new BufferedImage(300, 300,
BufferedImage.TYPE_INT_RGB);
Graphics g = bufIm.createGraphics();
logoPainter.paintLogo(g, sLogo);
File outfile = new File("motif.jpeg");
FileOutputStream outstream = new FileOutputStream(outfile);
com.sun.image.codec.jpeg.JPEGImageEncoder encoder =
com.sun.image.codec.jpeg.JPEGCodec.createJPEGEncoder(outstream);
encoder.encode(img);
}
Thanks in advance!!
Bert
