    functions. This helps you to compute related colors. To better
    understand their working check the module Graphics::Toolkit::Color. If
    you push the "Gradient" button that a smooth color gradient will be
    calculated between the leftmost color number one and the currently
    selected color. The value after the button skews the gradient towart the
    start (positive values) or the end (negative values). The "Complement"
    button also computes colors between color one and the current but these
    will have equally distanced hues but the same brightness and saturation.
    The text fields after the button allow you to skew the brightness and
    saturation. Behind that, at the rightmost position are two buttons to
    move the currently selected color around.

    The third section below that displays the colors than can be used to
    draw the picture. They are ten colors, numbered from left to right.
    Below each color field there is a second rectangle showing the status of
    the color. If this rectangle is empty, the status is normal (used). If
    it's crossed out, them the color is inactive because in the visual
    settings you choose to use less than ten colors. The third option is
    selected color. To select a color, just click on the rectangle
    displaying that color or the status rectangle below. Then the status
    will show an arrow down.

    This means the section below displays the values of this color. And the
    values can also be changed there. First your have the *red* (R), *green*
    (G) and *blue* (B) values of the RGB color space. below that are ones of
    HSB: *hue*, *saturation* and *lightness*. These are more meaningful to
    the human mind. At the right end of each row that shows amd changes one
    color value is a button with a question mark. Push that to randomize
    this one value.

    The last and fifth section is analogous to the first one. It is a store
    for your favorite single colors. Just load and safe the currently
    selected color via the buttons. Be again cautious with the "Del" button.

  Commands
    In the lower left corner are two rows of command buttons. All other
    commands are in the menu.

    The lower left part of the window contains buttons in two rows. The
    upper row is just for drawing the complete image. It has a progress bar
    and the draw button. If the progress bar is white, you see just a sketch
    drawing - a preview of the full image that can be computed fast enought
    to react to all setting changes. If you push the draw button (or
    <Ctrl>+<S>), you will get a full image and the progress bar has the
    color of the drawing and also can show you the color progression over
    time, so you can see, which are the early and the later parts of the
    drawing.

    The second button row is for easy mass production of drawings. The three
    text fields are combined the parts of the file path. The first text
    field is naturally the directory where the files get saved. You can
    change it by pushing the *Dir* in front (left) of the text button and
    use the then opening Dir-Dialog to select another directory. The second
    text field holds the base file name, which has to be inserted by
    clicking on in and typing. The third text field is the file number and
    is readonly. That counter increments automatically when a file is
    generated. The complete file path is <dir>+<base
    name>+'_'+<counter>+<file ending>. The file ending is *.ini* for setting
    files and *.jpg* or *.png* or *.svg* for image files. The exact ending
    depends on what is the current configuration set in the image > format
    menu. Lets say your directory is "/home/user/images/h" and the base file
    name is beauty. If there is already a file
    "/home/user/images/h/beauty_4.png" - the program will detect that and
    set the counter to 5. You can play with the settings and than (no matter
    if there is currently a complete drawing or not) push the *Save* button
    to produce a complete drawing into "/home/user/images/h/beauty_5.png".
    If you push the *INI* button you safe the current settings into
    "/home/user/images/h/beauty_5.ini". This file can later be loaded via
    settings menu to restore the current state of all buttons in the tabs.

  Menu
    The upmost menu bar has only three very simple menus. Please not that
    each menu shows which key combination triggers the same command and
    while hovering over an menu item you see a short help text the left
    status bar field.

    The first menu is for loading and storing setting files with arbitrary
    names. I recommend giving them the file ending ".ini" for transparency
    reasons. A submenu allows a quick load of the recently used files. The
    first entry lets you reset the whole program to the starting state and
    the last is just to exit (safely with saving the configs).

    The second menu has only two commands for drawing an complete image and
    saving it in an arbitrary named PNG, JPG or SVG file (the file ending
    decides). The submenu above only sets the preferred format, which is the
    format of the serially save images by the command buttons in the left
    lower corner. The preferred file format is also the first wild card in
    the save dialog. Above that is another submenu for setting the image
    size.

    The third menu has only one item to oben the *about* - dialog, where you
    can see which perl, Wx and other versions you are currently using.
