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.

Opportunity

Personal Opportunity - Free software gives you access to billions of dollars of software at no cost. Use this software for your business, personal use or to develop a profitable skill. Access to source code provides access to a level of capabilities/information that companies protect though copyrights. Open source is a core component of the Internet and it is available to you. Leverage the billions of dollars in resources and capabilities to build a career, establish a business or change the world. The potential is endless for those who understand the opportunity.

Business Opportunity - Goldman Sachs, IBM and countless large corporations are leveraging open source to reduce costs, develop products and increase their bottom lines. Learn what these companies know about open source and how open source can give you the advantage.

Free Software

Free Software provides computer programs and capabilities at no cost but more importantly, it provides the freedom to run, edit, contribute to, and share the software. The importance of free software is a matter of access, not price. Software at no cost is a benefit but ownership rights to the software and source code is far more significant.

Free Office Software - The Libre Office suite provides top desktop productivity tools for free. This includes, a word processor, spreadsheet, presentation engine, drawing and flowcharting, database and math applications. Libre Office is available for Linux or Windows.

Free Books

The Free Books Library is a collection of thousands of the most popular public domain books in an online readable format. The collection includes great classical literature and more recent works where the U.S. copyright has expired. These books are yours to read and use without restrictions.

Source Code - Want to change a program or know how it works? Open Source provides the source code for its programs so that anyone can use, modify or learn how to write those programs themselves. Visit the GNU source code repositories to download the source.

Education

Study at Harvard, Stanford or MIT - Open edX provides free online courses from Harvard, MIT, Columbia, UC Berkeley and other top Universities. Hundreds of courses for almost all major subjects and course levels. Open edx also offers some paid courses and selected certifications.

Linux Manual Pages - A man or manual page is a form of software documentation found on Linux/Unix operating systems. Topics covered include computer programs (including library and system calls), formal standards and conventions, and even abstract concepts.
