## Class Description

      TAttImage

      Image attributes are:
        Image Quality (see EImageQuality for the list of qualities)
        Compression defines the compression rate of the color data in the
                    internal image structure. Speed and memory depends
                    on this rate, but not the image display itself
                    0: no compression;  100: max compression
        Radio Flag: kTRUE  the x/y radio of the displayed image is always
                           identical to the original image
                    kFALSE the x and y size of the displayed image depends
                           on the size of the pad
        Palette:    Defines the conversion from a pixel value to the
                    screen color

      This class is used (in general by secondary inheritance)
      by some other classes (image display).

      TImagePalette

      A class to define a conversion from pixel values to pixel color.
      A Palette is defined by some anchor points. Each anchor point has
      a value between 0 and 1 and a color. An image has to be normalized
      and the values between the anchor points are interpolated.
      All member variables are public and can be directly manipulated.
      In most cases the default operator will be used to create a
      TImagePalette. In this case the member arrays have to be allocated
      by an application and will be deleted in the destructor of this
      class.

      We provide few predifined palettes:

        o gHistImagePalette - palette used in TH2::Draw("col")

        o gWebImagePalette
           The web palette is a set of 216 colors that will not dither or
           shift on PCs or Macs. Browsers use this built-in palette when
           they need to render colors on monitors with only 256 colors
           (also called 8-bit color monitors).
           The 6x6x6 web palette provides very quick color index lookup
           and can be used for good quality convertion of images into
           2-D histograms.

      TPaletteEditor

      This class provides a way to edit the palette via a GUI.

TPaletteEditor(TAttImage *attImage, UInt_t, UInt_t)

     Constructor.

void CloseWindow()

     Closes the window and deletes itself.
