💖 NCGM2CGM 💖

ok so bestie, we're in the NCAR GRAPHICS corner of the manual, and today's main characters are ncgm2ncgm... no wait, cgm2ncgm and ncgm2cgm. Two little filter icons that flip your metafiles back and forth. Let's get into it 🦋

✨ NAME ✨

cgm2ncgm, ncgm2cgm — filter NCAR CGM to/from vanilla CGM

🌸 SYNOPSIS 🌸

ncgm2cgm [ -s output block size ] [ -V ]

cgm2ncgm [ -s input block size ] [ -V ]

💅 DESCRIPTION 💅

okay so picture this: ncgm2cgm and cgm2ncgm are filters that convert back and forth between NCAR Computer Graphics Metafile (CGM) and vanilla CGM. literally the glow-up and the de-glow-up, no cap.

ncgm2cgm strips the wrapper from NCAR CGM records (she's taking off the accessories 💅) while cgm2ncgm restores it (putting the whole fit back on 👑).

and the way it does I/O?? from standard in/out respectively. so you just pipe it, periodt. 🎀

🎀 OPTIONS 🎀

  • -s size — sets the block size in bytes for reads/writes of vanilla CGM. the default blocking factor is 1024. lowkey important if you're being picky about chunk size ✨
  • -V — print the version number and then exit. she says hi and then she leaves 🙈

💀 BUGS 💀

ok so this part is a little messy, buckle up.

some vanilla metafile interpretors take advantage of shortcuts provided by their CGM generators. in effect, they are not true CGM interpretors. 😭

so here's the tea: although it will still be possible to convert these metafiles to NCAR format that may be interpreted by NCAR Graphics translators, it may not be the case that the aforementioned interpreters will be able to translate true vanilla metafiles, such as produced by ncgm2cgm.

translation bestie: the fake-vanilla interpreters might be able to go one way but not the other. don't @ me, that's just what the page says 💀
