Re: [Gimp-user] GIMP and fax

[Tobias Jakobs <tobias jakobs gmail com>]

Hello Neil,

I'm not sure that Gimp is the right tool, if you want some thing lighter
then ImageMagic. I would try VIPS [1], its optimized for speed and low
memory use [2]. Wikipedia changed form ImageMagic to VIPS last year. [3]

Regards
Tobias
