That is great, John - Thanks for the announcement.
(Have you been to the LGM in Toronto this year? I remember watching a VIPS talk in Montreal a few years ago) Best regards, js -><- On 7 May 2015 at 10:09, <jcup...@gmail.com> wrote: > Hi all, I hope no one minds me mailing this. > > I help maintain vips, a free image processing library, and we've just > released a new version, vips8.
