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.
