GIMP is the most popular image editing application for AmigaOS4. But if you feel that the basic version lacks some features, it’s easy to add more thanks to GIMP plugins and scripts. One of the best things about GIMP is the availability of tons of plugins, scripts, extensions, and other resources. Thanks to these goodies you can extend the functionality of the program in the direction you need. There are dozens of great GIMP extensions, so it was a challenge to pick only 5, but as these picks are emblematic of the power and flexibility of GIMP, I think they deserve the honor. Note that you need to install Python support for GIMP if you want to use Python-based plugins.
Liquid Rescale is a powerful plugin for GIMP that lets you resize any image without distortion, as well as remove selected parts of the image. If you’re familiar with Photoshop’s Content-Aware Scaling feature, you’ll understand what this plugin is for. There’s a helpful preview window within the plugin dialog which you can use to interactively tweak the parameters. When installed successfully, Liquid Rescale can be found in the “Layers” menu.
G’MIC is probably the most popular GIMP plugin – and rightfully so. It’s an image processing framework that contains hundreds of presets, filters and effects you can apply to your images. You can access them in the “Filters” menu, and if you’d like to test G’MIC before installation, there’s a completely usable online version that runs in your browser. How cool is that?
Resynthesizer is an exceptional plugin that every serious GIMP user should install. With this plugin, you can remove objects from photos, repeat textures for better tiling or seamless image healing, and transfer textures from one image to another. Have you heard of Content Aware Fill in Photoshop? Well, Resynthesizer is used for the same purpose, and apparently GIMP had it long before Photoshop.
This plugin is an absolute must for web designers, bloggers and anyone who needs to prepare visual materials for the Web. I use it every day, and honestly, I don’t know what I would do without it. Save for Web lets you compress, scale, smooth and crop images before uploading them, ensuring that they are not too big for your website. You can find it in GIMP’s “File” menu.
Filter Pack is a plugin that comes with GIMP by default, proving once again how awesome GIMP is. You can access it from the “Colors” menu, and it lets you adjust color settings for the entire image or just the selected part. Checking the boxes under “Windows” opens separate windows with variations of your image, and here you can click on each variation to apply (and intensify) its effect on the image.
