How Can I Save Image In JPG Format ???

[james35]

Hi,
I have linux ubuntu 7.04 and I use Imagemagick (version 7:6.2.4.5) to see images that I create with Octave. The problem is that I need to save these images not in the Octave's format (.img, right ?), but in JPG format. Imagemagick has a menù which it is possible to choose the option "save" using the mouse, but I want to save the image in JPG format from the console of octave, directly, using a command. Exist a command or a function that allows me to make this?

Thank You !!!

You want the 'imwrite' function from the 'image' package. You can
download this package from http://octave.sf.net.

I'd say
        print("/tmp/image.jpeg")
should do it.
