adjust Bitmap width and height in MapField in BlackBerry
I am drawing circles around a location point in the MapField like in the code given below:

     public void drawCircleMap(int [] radius)
    {
       int i = 0;
    	Graphics graphics = null;
    	int x2,y2;
    	bmparr = new Bitmap[radius.length];
        for(int j=0;j<radius.length;j++)
        {
    			    XYPoint fieldOut = new XYPoint();
    			    convertWorldToField(mPoints[1], fieldOut);
    				x2 = fieldOut.x;
                    y2 = fieldOut.y;
                    bmparr[i] = new Bitmap(getWidth(), getHeight());
                    bmparr[i].createAlpha(Bitmap.ALPHA_BITDEPTH_8BPP);
        	    	graphics = Graphics.create( bmparr[i]);
        	    	graphics.setColor(Color.BLUE);
        	    	graphics.drawEllipse(x2, y2, x2+radius[j], y2, x2,y2+radius[j], 0, 360);
        	    	graphics.fillEllipse(x2, y2, x2+radius[j], y2, x2,y2+radius[j], 0, 360);
        	    	i++;
        }
}

 

    protected void paint(Graphics graphics) {
    	super.paint(graphics);

    	for(int i =0 ;i < bmparr.length;i++)
    	{
            graphics.setGlobalAlpha(100);
            graphics.drawBitmap(0, 0,  bmparr[i].getWidth(), bmparr[i].getHeight(), bmparr[i], 0, 0);
        }
}

 I want to draw 4 circles, now as i draw more number of circles, the map seems to fade out, Can someone please tell me how i could solve this issue?
