.SH NAME
jsurf-alggeo \- Java based renderer for real SURFaces (ALGebraic GEOmetry dedicated tool)
.SH DESCRIPTION
usage: jsurf\-alggeo [options...] {jsurf_input|\-} [png_output|\-]
.PP
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 in a PNG file.
