Converting Gray Scale to RGB

Question

Can anybody tell me how to convert a Gray Scale image to RGB image?
I have written a Code:
public BufferedImage convertToRGB(BufferedImage input){
ColorSpace RGBSpace = ColorSpace.getInstance (ColorSpace.CS_LINEAR_RGB);
ColorConvertOp rgbConvert = new ColorConvertOp (RGBSpace, null);
BufferedImage output = new BufferedImage (input.getWidth(), input.getHeight(), BufferedImage.TYPE_INT_ARGB);
return rgbConvert.filter (input, output);
But this doesn't seem to work.
please help me
thanx

Answer 1

Try this:
public BufferedImage convertToRGB(BufferedImage input)
ColorSpace RGBSpace = ColorSpace.getInstance(ColorSpace.CS_sRGB);
ColorConvertOp rgbConvert = new ColorConvertOp(RGBSpace, null);
output = rgbConvert.filter(input, null);
return output;
}
