RadialGradientPaint problem

Java 2D
#1

Hi guys,

I’ve been banging my head against this particular brick wall for a couple of days now… I’m trying to create a circle that fills itself from transparent at the centre to black at the edges using RadialGradientPaint but I just can’t get it to work!

Here’s what I’m using right now:

RadialGradientPaint whiteToBlack = new RadialGradientPaint(
	50,  //  x centre
	50,  //  y centre
	50,  //  radius of fill
	new float[] { 0.0f, 1.0f },   //  start position of each color
	new Color[] { new Color(1f, 1f, 1f, 0f), Color.BLACK }, //  the colors
	CycleMethod.NO_CYCLE
);

lightG.setPaint( whiteToBlack );

//  draw in the centre of the screen, a 100x100 pixel oval
lightG.fillOval(this.width/2-50, this.height/2-50, 100, 100);

This is what it draws:

It seems to be completely ignoring the first color, I’ve tested with different colors and whichever is the second color I use, that’s the one that shows up.

Totally confused by it! ???

Any help gratefully received :slight_smile:
