Alternating Transparency Based on Double Variable

[YellowPainting]

Hi, I'm trying to change transparency with a double value. I've been using:

g2d.setComposite(java.awt.AlphaComposite.getInstance(java.awt.AlphaComposite.SRC_OVER, 0.1f));

Although, I can't figure out how to get it to work. Any explanation, alternate way of doing this, and any links on this are appreciated.

Thanks.

Thanks it helped. Should have looked there, lol.

    public void setTransparency(int length)
    {
        double num = (double)length/100.0;
        if (num > 1.0)
        {
            num = 1.0;
        }
        String temp = Double.toString(num);
        float test = Float.valueOf(temp).floatValue();
        g2d.setComposite(java.awt.AlphaComposite.getInstance(java.awt.AlphaComposite.SRC_OVER, test));
    }
