 width of the affected region of a rake by a factor of 10, either
 reduce **V** by a factor of 10 or reduce **D** by a factor of 3.1 (sqrt 10).

+              to the right (positive)
+
+## background
+
+The **background** option now can use the color schemes **rgb** and **RGB**
+
+With **rgb** we use decimals between 0 and 1
+
+With **RGB** we use integers between 0 and 255
+
+The colors then are automatically detected correctly.

+    arc-drops
+    spiral-drops
+
+and automatically detected.

-- /stroke
-- /rake

 They make it possible to create a very large variety of marblings with combinations of the various actions.
 
 Initially there are drops of colors that the artist spreads with a brush on the surface (a bit of a hazard, even if they are located in a given region) and whose size depends on the brush. He performs the operation several times with other colors and also brushes of different sizes. These single drops, circular in shape, are placed with the following command
 \begin{verbatim}
-    cx cy r [bgc] [rgb]
-   [ 0 0 100 [] [0 0 1] /drop]
+    cx cy r [rgb]
+    0 0 100 [0 0 1] drop

-Note, that the coordinates (\texttt{cx, cy}) of the center of the drop and its radius \texttt{r} are in points, the colors need to be setup in the rgb-color-system: (values between 0 and 1). Details are given in the following sections. So this is the first phase: arrange the drops on the surface in several stages with different radii and colors. To facilitate the experimentation of different types of actions, Aubrey Jaffer imagined an initial background obtained by dropping (one after the other) drops of different colors (we can also differentiate their radii) at the same point, they all have the same center, we then obtain an initial background consisting of concentric rings, named ``concentric-bands''.

 Aubrey Jaffer coded all the possible simulations with the expected deformations (rake, stroke, stir, wiggle, vortex) in pure PostScript and his new code, perfectly structured, and whose use is very simple, would be enough to itself, if it weren't necessary for each test, to add lines, delete others, save them within the original PostScript file \ldots

 Consider a single stylus (a cylinder of diameter \texttt{D}) that is placed on the $Oy$-axis at a distance $r$ from the chosen center. In a circular motion, the artist rotates the stylus by an angle $\theta$. The angular velocity will influence the shape of the deformation. The direction of rotation is fixed by the sign of $\theta$. If $\theta>0$ the artist rotates counterclockwise \footnote{The sign of $r$ can also indicate the direction of rotation. If $r<0$ the direction of the rotation fixed by $\theta$ inverts.}.
