Method Detail

### flipImageVertically

    public static void flipImageVertically(BufferedImage image)

  Flips the supplied BufferedImage vertically. This is often a necessary conversion step to display a Java2D image correctly with OpenGL and vice versa.

### createCompatibleImage

    public static BufferedImage createCompatibleImage(int width,
                                                      int height)

  Creates a `BufferedImage` with a pixel format compatible with the graphics environment. The returned image can thus benefit from hardware accelerated operations in Java2D API.

  Parameters:
    `width` - The width of the image to be created
    `height` - The height of the image to be created
  Returns:
    A instance of `BufferedImage` with a type compatible with the graphics card.

### createThumbnail

    public static BufferedImage createThumbnail(BufferedImage image,
                                                int thumbWidth)

  Creates a thumbnail from an image. A thumbnail is a scaled down version of the original picture. This method will retain the width to height ratio of the original picture and return a new instance of `BufferedImage`. The original picture is not modified.

  Parameters:
    `image` - The original image to sample down
    `thumbWidth` - The width of the thumbnail to be created
  Returns:
    A thumbnail with the requested width or the original picture if thumbWidth = image.getWidth()
  Throws:
    `IllegalArgumentException` - If thumbWidth is greater than image.getWidth()
