# qfractalnow(1)

Explore fractals and generate fractal images.

## NAME

qfractalnow - Explore fractals and generate fractal images.

## SYNOPSYS

**qfractalnow** \[OPTIONS\]

## DESCRIPTION

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.

## 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).

- **-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.
