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.

-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.
