## NAME
       pamstretch-gen - use pamstretch and pnmscale to scale by non-integer values


## SYNOPSIS
       **pamstretch-gen** _N_ [_pnmfile_]


## DESCRIPTION
       **pamstretch-gen** is a program which uses [**pamstretch**(1)](https://www.chedong.com/phpMan.php/man/pamstretch/1/markdown), [**pnmfile**(1)](https://www.chedong.com/phpMan.php/man/pnmfile/1/markdown), and [**pnmscale**(1)](https://www.chedong.com/phpMan.php/man/pnmscale/1/markdown) 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. :-)


## BUGS
       Uses  awk  just  to make some simple floating-point calculations, which is probably overkill.
       But using dc makes my head hurt.
