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.
