The following color table can be used to convert a RGB image to an IndexColorModel image with 16 colors.  Does anyone know  how to create the color tables of 32, 64, 128 ,256 colors  for IndexcolorModel image. ?

int[] cmap = { 0xff000000, 0xff0000ff, 0xff00ff00, 0xff00ffff, //8 primary colors
                      0xffff0000, 0xffff00ff, 0xffffff00, 0xffffffff, // ...
                  0xff1c1c1c, 0xff383838, 0xff555555, 0xff717171, //8 shades of gray
                  0xff8e8e8e, 0xffaaaaaa, 0xffc7c7c7, 0xffe3e3e3      };

Are you wanting the optimal palette? or just any old palette?

There are many different algorithms for reducing the number of colors in an image - you just have to look at a paint package such as photoshop or psp to know that.

The optimal palette.  Where can I find more information about it ?  I tried different color reducing algorithms such as octree along with dithering process.
But I found that using bufferedimage is the pretty easy, efficient and produces good results.
