GIMP - Adobe Photoshop Equivalent

Feature Overview

GIMP is a versatile graphics manipulation package.

Customizable Interface

Each task requires a different environment and GIMP allows you to customize the view and behavior the way you like it. Starting from the widget theme, allowing you to change colors, widget spacings and icon sizes to custom tool sets in the toolbox. The interface is modulized into so called docks, allowing you to stack them into tabs or keep them open in their own window. Pressing the tab key will toggle them hidden.

GIMP features a great fullscreen mode allowing you to not only preview your artwork but also do editing work while using the most of your screen estate.
Photo Enhancement

Numerous digital photo imperfections can be easily compensated for using GIMP. Fix perspective distortion caused by lens tilt simply choosing the corrective mode in the transform tools. Eliminate lens' barrel distortion and vignetting with a powerful filter but a simple interface.

The included channel mixer gives you the flexibility and power to get your B/W photography stand out the way you need.

Digital Retouching

GIMP is ideal for advanced photo retouching techniques. Get rid of unneeded details using the clone tool, or touch up minor details easily with the new healing tool. With the perspective clone tool, it's not difficult to clone objects with perspective in mind just as easily as with the orthogonal clone.
Hardware Support

GIMP includes a very unique support for various input devices out of the box. Pressure and tilt sensitive tablets, but also a wide range of USB or MIDI controllers. You can bind often-used actions to device events such as rotating a USB wheel or moving a MIDI controller's slider. Change the size, angle or opacity of a brush while you paint, bind your favorite scripts to buttons. Speed up your workflow!

File Formats

The file format support ranges from the common likes of JPEG (JFIF), GIF, PNG, TIFF to special use formats such as the multi-resolution and multi-color-depth Windows icon files. The architecture allows to extend GIMP's format capabilities with a plug-in. You can find some rare format support in the GIMP plugin registry.

Thanks to the transparent virtual file system, it is possible to load and save files to from remote locations using protocols such as FTP, HTTP or even SMB (MS Windows shares) and SFTP/SSH.

To save disk space, any format can be saved with an archive extension such as ZIP, GZ or BZ2 and GIMP will transparently compress the file without you needing to do any extra steps.

Scribus - InDesign Equivalent

Scribus supports most major graphic formats in addition to SVG. Professional type/image setting features include CMYK colors and ICC color management. Although written in C++, it has built-in scripting using Python. It is available in more than 24 languages.

Printing is achieved via its own internal level 3 PostScript driver, including support for font embedding and sub-setting with TrueType, Type 1 and OpenType fonts. The internal driver fully supports Level 2 PostScript constructs and a large subset of Level 3 constructs.

PDF support includes transparency, encryption and a large set of the PDF 1.4 spec as well as PDF/X3, including interactive PDFs form fields, annotations and bookmarks. However, although PDF export is very good, it is not currently able to import/edit PDF files, and PDFs exported from Scribus are not searchable in Acrobat Reader if the document contains proportional fonts.[2][3]

The file format, called SLA, is based on XML and is fully documented. Text can be imported from OpenDocument text documents, as well as RTF, Microsoft Word .doc, and HTML formats (although limitations apply).

Scribus cannot read or write the native file formats of commercial programs like QuarkXPress, Microsoft Publisher, and InDesign; the developers feel that reverse engineering those file formats would be prohibitively complex and could risk legal action from the makers of those programs.[4]

Although Scribus supports Unicode character encoding, it currently does not properly support complex script rendering and so cannot be used with Unicode text for languages written with Arabic, Indic and South East Asian writing systems.[5][6]
  
 
Inkscape - Illustrator Equivalent
 
About 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.
