-<h4>DESCRIPTION</h4>
-
-
-<blockquote>
-<tt><a href=Image.colortable.html#create>create</a></tt> initiates a colortable object.
- Default is that no colors are in the colortable.
-
-<p> <tt><a href=Image.colortable.html#add>add</a></tt> takes the same argument(s) as
- <tt><a href=Image.colortable.html#create>create</a></tt>, thus adding colors to the colortable.
-
-<p> The colortable is mostly a list of colors,
- or more advanced, colors and weight.
-
-<p> The colortable could also be a colorcube, with or
- without additional scales. A colorcube is the by-far
- fastest way to find colors.
-
-<p> Example:
- <pre>
- ct=colortable(my_image,256); // the best 256 colors
- ct=colortable(my_image,256,({0,0,0})); // black and the best other 255
-
-<p> ct=colortable(({({0,0,0}),({255,255,255})})); // black and white
-
-<p> ct=colortable(6,7,6); // a colortable of 252 colors
- ct=colortable(7,7,5, ({0,0,0}),({255,255,255}),11);
- // a colorcube of 245 colors, and a greyscale of the rest -> 256

-object <b>cubicles</b>(int r, int g, int b)<br>
-object <b>cubicles</b>(int r, int g, int b, int accuracy)</tt>
-</blockquote>
-
-<h4>DESCRIPTION</h4>
-
-
-<blockquote>
-Set the colortable to use the cubicles algorithm to lookup
- the closest color. This is a mostly very fast and very
- accurate way to find the correct color, and the default
- algorithm.
-
-<p>
- The colorspace is divided in small cubes, each cube
- containing the colors in that cube. Each cube then gets
- a list of the colors in the cube, and the closest from
- the corners and midpoints between corners.
-
-<p> When a color is needed, the algorithm first finds the
- correct cube and then compares with all the colors in
- the list for that cube.
-
-<p> example: <tt>colors=Image.colortable(img)->cubicles();</tt>
-
-<p> algorithm time: between O[m] and O[m * n],
- where n is numbers of colors and m is number of pixels
-
-<p> The arguments can be heavy trimmed for the usage
- of your colortable; a large number (10�10�10 or bigger)
- of cubicles is recommended when you use the colortable
- repeatedly, since the calculation takes much
- more time then usage.
-
-<p> recommended values:
-
-<p> <pre>
- image size setup
- 100�100 cubicles(4,5,4) (default)
- 1000�1000 cubicles(12,12,12) (factor 2 faster than default)
- </pre>
-
-<p> In some cases, the <tt><a href=Image.colortable.html#full>full</a></tt> method is faster.

-<dt><tt>int accuracy</tt>
- <dd>Accuracy when checking sides of cubicles.

- <pre>
- ({object image,object|int mask})
- ({object image,object|int mask,int opaque_value})
- ({object image,object|int mask,int opaque_value,int method})
- </pre>
- Given 0 as mask means the image is totally opaque.
-
-<p> Default opaque value is 255, only using the mask.
-
-<p> Methods for now are:
- <pre>
- 0 no operation (just paste with mask, default)
- 1 maximum (`|)
- 2 minimum (`&)
- 3 multiply (`*)
- 4 add (`+)
- 5 diff (`-)
- </pre>
- The layer image and the current source are calculated
- through the given method and then pasted using the mask
- and the opaque channel value.
-
-<p> All given images must be the same size.
