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.
