GIMP

GIMP is an acronym for GNU Image Manipulation Program. It is a freely distributed program for such tasks as photo retouching, image composition and image authoring. It has many capabilities. It can be used as a simple paint program, an expert quality photo retouching program, an online batch ... [More] processing system, a mass production image renderer, an image format converter, etc. GIMP is expandable and extensible. It is designed to be augmented with plug-ins and extensions to do just about anything. The advanced scripting interface allows everything from the simplest task to the most complex image manipulation procedures to be easily scripted. GIMP is written and developed under X11 on UNIX platforms. But basically the same code also runs on MS Windows and Mac OS X. [Less]

ImageMagick

ImageMagick® is a software suite to create, edit, and compose bitmap images. It can read, convert and write images in a variety of formats (over 100) including DPX, EXR, GIF, JPEG, JPEG-2000, PDF, PhotoCD, PNG, Postscript, SVG, and TIFF. Use ImageMagick to translate, flip, mirror, rotate, scale ... [More] , shear and transform images, adjust image colors, apply various special effects, or draw text, lines, polygons, ellipses and Bézier curves. The functionality of ImageMagick is typically utilized from the command line or you can use the features from programs written in your favorite programming language. ImageMagick is free software delivered as a ready-to-run binary distribution or as source code that you may freely use, copy, modify, and distribute in both open and proprietary applications. [Less]

Krita

claimed by KDE

Krita is a painting and image editing application. Krita contains both ease-of-use and fun features like guided painting (never before has it been so easy to airbrush a straight line!) and high-end features like support for 16 bit images, CMYK, L*a*b and even OpenEXR HDR images. Krita supports ... [More] many managed colorspaces, like rgb, grayscale, cmyk, lab, ycbcr and lms, in 8 and 16 bits per channel. Some colorspaces even support 32 bits per channel! Krita can import RAW images in 8 and 16 bits per channel and load and save the usual image formats: tiff, png, jpeg. Krita has image layers, group layers, adjustment layers and the innovative part layers: any KOffice document can be embedded as a layer in Krita. Krita is scriptable in Python and Ruby. [Less]

VIPS

The VIPS library/image processing system is well suited for larger than RAM true and false-colour images. VIPS can be used for image format conversion, colour calibration, image filtering, transformation and analysis, thumbnail generation, small object recognition and many other image processing ... [More] tasks. VIPS is well suited for medical and scientific research & development and batch image processing. It is not so good for retouching photographs. The system has two main parts: libvips is the library, and nip2 is the GUI. Both execute common image processing tasks faster than other image processing systems because of sophisticated memory/task management and multicore compatibility. VIPS runs in batch (command line) mode on *nix, Windows, Mac and other OSes. [Less]

Phatch

Phatch is an user friendly, cross-platform Photo Batch Processor and Exif Renamer with a nice graphical user interface. Phatch handles all popular image formats and can duplicate (sub)folder hierarchies. Phatch can batch resize, rotate, apply shadows, perspective, rounded corners, … and do much ... [More] more actions in minutes instead of hours or days if you do it manually. [Less]

NIP2

nip2, the "free love child of Photoshop and Excel," is the GUI of vips. You don't directly edit images --- instead, like a spreadsheet, you build relationships between objects. nip2 actively manages these relationships: if you change an object property, the change is propagated ... [More] "spreadsheet-style." Like vips, nip2 is fast and needs little memory. You can comfortably work with multi-gigabyte images on very modest hardware. In addition to the visual programming interface accessible through the GUI, nip2 has command-line and batch modes. It even has its own functional programming language (for writing extensions). [Less]
