GIMP 2.x

GIMP 2.x

There is not much to say about the best image application for Linux. GIMP 2.x has too many improvements to list.

However, setting up GIMP for print work with Scribus requires some adjustments to the defaults as shown below:

Lanczos Interpolation

Like most image editors, GIMP's defaults are setup primarily for web site images, meaning waaaay too little resolution for print. So first thing, set the defaults to a minimum of 144 DPI in resolution. Remember using these higher resolutions will result in much larger size files, so you might also need to adjust maximum settings for memory usage as well in GIMP preferences.

DPI Defaults

The other notable addition is the beginnings of some very basic color managed "soft proofs" of your images. This is available via LittleCMS also used by Scribus. You can set this in the preferences. Where this will help you is to see how it will look when transformed into a CMYK color space when printed or exported as PDF.
