FRACTALNOW(1) Fractal generator FRACTALNOW(1)

NAME

fractalnow - Generate fractal images.

SYNOPSYS

fractalnow [OPTIONS] -c <Config> [-x <Width>|-y <Height>] -o <Output>
 
fractalnow [OPTIONS] -f <Fractal> -r <Rendering> [-x <Width>|-y <Height>] -o <Output>

DESCRIPTION

FractalNow is a command line tool that generates pictures of fractals as Portable PixMap (PPM) files.
 
It is multi-threaded and implements advanced algorithms and heuristics that make computation very fast compared to most existing free fractal generators.
 
See QFractalNow, a graphical tool to explore fractals.

OPTIONS

-h
Print help.
-q
Quiet mode, only errors are displayed.
-v
Verbose mode.
-j <NbThreads>
Specify number of threads (see help for default value).
-g <GradientFile>
Specify gradient file, overriding gradient from configuration/ rendering file.
-l <FloatType>
Specify float type:
single Single precision.
 
double Double precision.
 
ldouble Long double precision.
 
mp Multiple precision.
-L <MPPrecision>
Specify precision of Multiple Precision (MP) floats (see help for default value).
-a <AntiAliasingMethod>
Specify anti-aliasing method:
none By default.
 
blur Gaussian blur.
 
oversampling Oversampling.
 
adaptive Smart oversampling.
-s <AAMSize>
Specify size for anti-aliasing:
Radius for blur (values in [2.5, 4] are generally good).
 
Scale factor for oversampling ([3, 5] is good for a high quality image).
 
Scale factor for adaptive (integers between 3-5 are good for a high quality image).
-p <AAMThreshold>
Threshold for adaptive anti-aliasing (see help for default value).
-i <QuadSize>
Maximum size of quadrilaterals for linear interpolation.
Default is good for no visible loss of quality (see help for default value).
 
1 means no interpolation (all pixels are computed).
-t <Threshold>
Dissimilarity threshold for quad interpolation.
Default is good for no visible loss of quality (see help for default value).
 
A quadrilateral that shows too dissimilar values at its corners will be computed, as opposed to interpolated.
