Method Detail

createScaledImage

public static BufferedImage createScaledImage(Image img,
                                              int type,
                                              double scale)

createGrayScaledImage

public static BufferedImage createGrayScaledImage(Image image,
                                                  int type)

Returns a gray-scaled BufferedImage based on the specified Image, with the specified type. The type must be a valid BufferedImage type.

createGrayScaledImage

createShadowImage

public static BufferedImage createShadowImage(Image image,
                                              int type,
                                              Color shadowColor)

Returns a BufferedImage representing the shadow of the specified Image, with the specified type. The type must be a valid BufferedImage type. The operation works as follows: all pixels will have the specified RGB color, but the alpha value will be copied from the corresponding pixel in the specified image. Note that a white pixel will also be transformed in a shadow pixel, only purely transparent pixels will also be fully transparent in the result image.

                                              Color shadowColor)

createMonotoneImage

public static BufferedImage createMonotoneImage(Image image,
                                                int type)

toBufferedImage

public static BufferedImage toBufferedImage(Image image,
                                            int type)

Returns a BufferedImage with the specified type on which the specified Image has been drawn.
