dzsave not found on mac

[PetterRanefall]

We are trying to use vips dzsave from command-line. On Windows it works fine, but on Mac we get an error message "dzsave: not found". For the mac we have fetched vips via macports.org. Do you have any idea what can be the problem?

Hi, you need to put "vips" in front, with no .exe. Start Terminal and type

john@katamata ~/pics $ vips dzsave k2.jpg x

(don't type the prompt, obviously, just the stuff starting "vips ...")

Thats what we did, and it works fine on Windows, but on the mac we get "dzsave: not found", i.e. the problem is not that it doesn't find vips, but that it doesn't find dzsave.

Ah sorry, I misunderstood. The problem is that the vips on Macports is too old. It's 7.26 which is now almost five years old, and well before dzsave was added.

I maintain the vips on homebrew, so that one is up to date. There are some install notes here:

You could also try fink.

The current macports ticket to update vips is here: https://trac.macports.org/ticket/41313 perhaps it'll be updated soon.

That explains it. Now it works. Thanks!

Good stuff, I'll close.
