pamstretch-gen – use pamstretch and pnmscale to scale by non-integer
pamstretch-gen N [pnmfile]
pamstretch-gen is a program which uses pamstretch, pnmfile, and
pnmscale to smoothly scale up a PNM file by any ratio; it’s like a
more general version of pamstretch (hence the name). But other than the
`any ratio’ bit, it’s much the same as pamstretch. 🙂
Uses awk just to make some simple floating-point calculations, which is
probably overkill. But using dc makes my head hurt.
