Inkscape |
An Open Source vector graphics editor, with capabilities similar to Illustrator, CorelDraw, or Xara X, using the W3C standard Scalable Vector Graphics (SVG) file format.
Inkscape supports many advanced SVG features (markers, clones, alpha blending, etc.) and great care is taken in designing a streamlined interface. It is very easy to edit nodes, perform complex path operations, trace bitmaps and much more. We also aim to maintain a thriving user and developer community by using open, community-oriented development.
What is 'Scalable Vector Graphics'?
Scalable Vector Graphics (SVG) is an open, industry-standard XML-based format for vector graphics developed by the W3C. Its acceptance is growing fast. Most vector editors these days can import and export SVG, and modern browsers (such as Firefox and Opera) can display it directly, i.e. without requiring any plugins. (For Internet Explorer, there's an SVG Viewer plugin from Adobe.)

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 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.
File Handling :
* File formats supported include bmp, gif, jpeg, mng, pcx, pdf, png, ps, psd, svg, tiff, tga, xpm, and many others
Painting :
* Full suite of painting tools including Brush, Pencil, Airbrush, Clone, etc.
* Sub-pixel sampling for all paint tools for high quality anti-aliasing
* Extremely powerful gradient editor and blend tool
* Supports custom brushes and patterns
Animation :
* Load and save animations in a convenient frame-as-layer format
* MNG support
* Frame Navigator (in GAP, the GIMP Animation Package)
* Onion Skin (in GAP, the GIMP Animation Package)

Scribus |
Is an Open Source program that brings professional page layout to Linux/UNIX, Mac OS X, OS/2 Warp 4/eComStation and Windows desktops with a combination of press-ready output and new approaches to page design.
Underneath a modern and user-friendly interface, Scribus supports professional publishing features, such as color separations, CMYK and Spot Color support, ICC color management or versatile PDF creation.
* Scribus uses an XML-based file format, so that Scribus files (SLA) can be easily edited with a text editor or manipulated via Scripts (Perl, Python etc.).
* Frames that can be edited more flexibly than in most other DTP programs.
* Master Pages and Page Palettes allow for easy page management
* Document-wide layers: Items can be moved between layers, and it's possible to apply blend modes and transparancy to individual layers.
* Object linking, grouping, moving, locking, resizing and converting between different object types.
* A sophisticated Scrapbook allows for easy sharing of design objects (such as text blocks, logo images, backgrounds etc.) between documents or via a network.
* Render Frames allow for importing LaTeX formulas and other markup content directly into frames, as well as editing the markup code in an integrated editor.
Professional Publishing Features:
* Creation of CMYK color PostScript separations.
* Creation of RGB, CMYK and Greyscale PDF files.
* Full support for Level 2 PostScript output, a very large subset of Level 3 and support for PDF 1.4/1.5 features including transparency, gradients and 128 bit security.
* Full Compliance with PDF/X-3.
* Supports font embedding and subsetting in both PostScript and PDF export.
* Advanced pre-press features, like bleed and printing marks
* Creation of PDF forms, including nearly all PDF field types, and JavaScript actions.
* Creation of PDF presentations, including presentation effects.
