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.
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.
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).
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).
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.
A quadrilateral that shows too dissimilar values at its corners will be computed, as opposed to interpolated.
