    The second section is for people who want only a few color regions. Just
    activate the custom checkbox and select the "Steps" count. If they are
    at 20 only 20 differently colored reagions are drawn. The readonly
    textbox below with the current iteration max is only for better
    orientation. When it is at lets say 60 you know: this scale of one to 60
    possible iteratons will be divided into 20 parts. If the distribution is
    *linear* they all have the size of three. But you might want to skew the
    color distribution. The mapping types are sorted by their skewness.

    If the second section is deactivated you are able to activate the third.
    It is for folks that think that the color gradient is not dense enough.
    That might makes sense if the iteration already stops at maximum of 5
    but you want to get a long smooth gradient. Then you want to *Activate*
    subgradients, based on the Value at iteration stop. The greater that is
    the further on the subgradient the resulting color will be. The five
    options here parallel what we already described. Subgradients will have
    the amount of steps as dialed in under "Steps". The gradient will be
    computed from 1 (above bailout value) up to the "Size" value. Everything
    above just lands in the last bucket. The subgradient can again be skewed
    by a "Distribution" and "Dynamic" value (as described above). Also the
    resulting color change dependant in which color "Space" it is computed
    in. *RBG* gives usually more smooth results and *HSL* more contrast.

  Colors
    This page helps you to select the color that will be used to paint the
    fractal. You can see them in the middle row. The background color is
    often the one at the most left. That is why it is marked by a vertical
    bar. The colors are numbered from left to right with 1 to 11.

    The first section on the pages is for loading and saving custom sets of
    colors. Please use the delete button carefully. "New" saves the current
    colors under a new name, "Save" under the current name. There are no
    undo buttons yet.

    The section below helps you to compute related colors beweet the second
    and the currently selected. This can be either a gradient (with
    "Gradient" button). Right beside is a text box to skew the gradient in
    one or anotehr direction. To get complementary colors push the
    "Complement" button. This also can be skewed on the saturation and
    lightness axis (text boxes beside). The arrow butons there help you to
    move colors to another position.

    To change a color you have to fist select it by clicking on it or the
    marker below. After that the marker turns into an arrow pointing down.
    Because below are the 6 slider to change the either RGB or HSL values of
    the color. Each slider has a randomize button with a quastion mark.

    The second method to change the selected color is to load one from the
    store (last section below). Just select the color by drop down menu or
    arrows. If you like the seen color push "Load". This single color store
    has also Buttons to store your own favorite colors or delete the ones
    you dont like. The only way to bring back deleted default colors is to
    delete the config file: ~/.config/juliagraph.

  Mouse
    The drawing board responds to three types of clicks. A left click moves
    the visible section. Double click means zoom in and right click is zoom
    out.

  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. Also a sub menu 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 onle set the preferred format, which is the
    format of serial images and the first wild card in dialog. Above that is
    another submenu for setting the image size.

    The third menu has only one item that opens a help dialog. That displays
    some core information about author, version number and a link to this
    page, the main documentation.
