5.10 Doodad Parameters
LOGMAP=yes|old|n
Selects a compressed relationship between escape-time iterations and
palette colors. See "Logarithmic Palettes and Color Ranges" (p. 93)
for details.
LOGMODE=fly/table|auto
Forces the use of the on-the-fly routine or the logarithm table for the
calculation of log palettes. Not normally needed. The auto option
cannot be used at the same time as the other two. Auto causes the
logmap value to be automatically recalculated when zooming. Changing
almost anything will turn this feature off. Set logmode=auto from the
<g> screen prompt.
RANGES=nn/nn/nn/...
Specifies ranges of escape-time iteration counts to be mapped to each
color number. See "Logarithmic Palettes and Color Ranges" (p. 93) for
details.
DISTEST=nnn/nnn
A nonzero value in the first parameter enables the distance estimator
method. The second parameter specifies the "width factor", defaults to
71. See "Distance Estimator Method" (p. 91) for details.
DECOMP=2|4|8|16|32|64|128|256
Invokes the corresponding decomposition coloring scheme. See
Decomposition (p. 93) for details.
BIOMORPH=nnn
Turn on biomorph option; set affected pixels to color nnn. See
Biomorphs (p. 95) for details.
POTENTIAL=maxcolor[/slope[/modulus[/16bit]]]
Enables the "continuous potential" coloring mode for all fractal types
except plasma clouds, attractor types such as lorenz, and IFS. The four
arguments define the maximum color value, the slope of the potential
curve, the modulus "bailout" value, and whether 16 bit values are to be
calculated. Example: "POTENTIAL=240/2000/40/16bit". The Mandelbrot and
Julia types ignore the modulus bailout value and use their own hardwired
value of 4.0 instead. See Continuous Potential (p. 95) for details.
INVERT=nn/nn/nn
Turns on inversion. The parameters are radius of inversion, x-coordinate
of center, and y-coordinate of center. -1 as the first parameter sets
the radius to 1/6 the smaller screen dimension; no x/y parameters
defaults to center of screen. The values are displayed with the <Tab>
command. See Inversion (p. 92) for details.
FINATTRACT=no|yes
Another option to show coloring inside some Julia "lakes" to show escape
time to finite attractors. Works with lambda, magnet types, and possibly
others. See Finite Attractors (p. 185) for more information.
EXITNOASK=yes
This option forces Fractint to bypass the final "are you sure?" exit
screen when the ESCAPE key is pressed from the main image-generation
screen. Added at the request of Ward Christensen. It's his funeral
<grin>.
