        public static java.awt.image.BufferedImage loadCompatibleImage​(java.net.URL resource)
                                                        throws java.io.IOException
        Loads the image at the URL and makes it compatible with the screen. If loading the url fails then this method will either throw an IOException or return null.
        Throws:

      • loadCompatibleImage

        public static java.awt.image.BufferedImage loadCompatibleImage​(java.io.InputStream in)
                                                        throws java.io.IOException
        Throws:
        java.io.IOException

      • toCompatibleImage

        public static java.awt.image.BufferedImage toCompatibleImage​(java.awt.image.BufferedImage image)

      • setMergedClip

        public static java.awt.Shape setMergedClip​(java.awt.Graphics2D g,
                                           java.awt.Shape newClip)
        Sets then clip on a graphics object by merging with the existing clip instead of replacing it. The new clip will be an intersection of the old clip and the passed in clip shape. The old clip shape will be returned

      • resizeGradient

        public static java.awt.Paint resizeGradient​(java.awt.Paint p,
                                            int width,
                                            int height)
        Resizes a gradient to fill the width and height available. If the gradient is left to right it will be resized to fill the entire width. If the gradient is top to bottom it will be resized to fill the entire height. If the gradient is on an angle it will be resized to go from one corner to the other of the rectangle formed by (0,0 -> width,height). This method can resize java.awt.GradientPaint, java.awt.LinearGradientPaint, and the LinearGradientPaint implementation from Apache's Batik project. 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.
