/** Resizes a gradient to fill the width and height available.

Note, * this method does not require the MultipleGradientPaint.jar from Apache to * compile or to run. MultipleGradientPaint.jar *is* required if you want * to resize the LinearGradientPaint from that jar. * * Any paint passed into this method which is not a kind of gradient paint (like * a Color or TexturePaint) will be returned unmodified. It will not throw * an exception. If the gradient cannot be resized due to other errors the * original paint will be returned unmodified. It will not throw an * exception.// ww w . java2s . co m * */ public static Paint resizeGradient(Paint p, int width, int height) { if (p == null) return p; if (p instanceof GradientPaint) { GradientPaint gp = (GradientPaint) p; Point2D[] pts = new Point2D[2]; pts[0] = gp.getPoint1(); pts[1] = gp.getPoint2(); pts = adjustPoints(pts, width, height); return new GradientPaint(pts[0], gp.getColor1(), pts[1], gp.getColor2(), gp.isCyclic()); } if ("java.awt.LinearGradientPaint".equals(p.getClass().getName()) || "org.apache.batik.ext.awt.LinearGradientPaint".equals(p.getClass().getName())) { return resizeLinearGradient(p, width, height); } return p; }
