qfractalnow [OPTIONS]

QFractalNow is a graphical tool, based on Qt library, that allows users to explore fractals intuitively and generate pictures.

It is multi-threaded and implements advanced algorithms and heuristics that make computation very fast compared to most existing free fractal generators.

See FractalNow, a command-line tool to generate fractal images.

-h

Print help.

-q

Quiet mode, only errors are displayed.

-v

Verbose mode.

-j <NbThreads>

Specify number of threads (see help for default value).

-c <ConfigFile>

Specify configuration file, overriding default configuration.

-f <FractalFile>

Specify fractal file, overriding parameters from default configuration or configuration file.

-r <RenderingFile>

Specify rendering file, overriding parameters from default configuration or configuration file.

-g <GradientFile>

Specify gradient file, overriding gradient from default configuration, configuration file, or rendering file.

-x <Width>

Specify image width.

-y <Height>

Specify image height.

-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.

-m <MinAAMSize>

Specify minimum size of adaptive anti-aliasing (see help for default value).

Must be an integer strictly greater than 1.

-M <MaxAAMSize>

Specify maximum size of adaptive anti-aliasing (see help for default value).

Must be an integer strictly greater than 1 and MinAAMSize.

-n <AAMSizeIteration>

Anti-aliasing size iteration.

Anti-aliasing size will increase by steps of AAMSizeIteration from MinAAMSize to MaxAAMSize.

-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.
