NAME

       jsurf-alggeo - Java based renderer for real SURFaces (ALGebraic GEOmetry dedicated tool)

DESCRIPTION

       usage: jsurf-alggeo [options...] {jsurf_input|-} [png_output|-]

       jsurf-alggeo  is a renderer for real algebraic surfaces.  jsurf-alggeo translates its own language script
       files (generally with extension '.jsurf') into Portable Network Graphics (PNG) files;  PNG  is  a  raster
       graphics  file  format that supports lossless data compression.  If the output filename is not specified,
       the output is placed in a file of the same basename with  a  '.png'  extension  in  the  current  working
       directory.   Either the input filename or the output filename can be '-' to request reading from stdin or
       writing to stdout, respectively. Whenever the Graphic Unit Interface (GUI) is available, the  gui  option
       takes  precedence  over  the output options, otherwise it is ignored. That is, whenever the gui option is
       present (and available), the output is displayed in a window rather than written to a PNG file.

       --gui  display rendering (overrides output options)

       --help display this help text and exit

       -o,--output <arg>
              output PNG into this file (overrode by the 2nd argument if present)

       -q,--quality <arg>
              quality of the rendering: 0 (low), 1 (medium, default), 2 (high), 3 (extreme)

       -s,--size <arg>
              image width and height (default: 512)

       --version
              print program version and exit
