5 Highly Promising Terminal Emulators
The terminal emulator is a venerable but essential tool for computer users. The reason why Linux offers so much power is due to the command line. The Linux shell can do so much, and this power can be accessed on the desktop by using a terminal emulator. There are so many available for Linux that the choice is bewildering.

  • PosteRazor
    The PosteRazor cuts a raster image into pieces which can afterwards be printed out and assembled to a poster.
  • potrace
    potrace is a utility for tracing a bitmap, which means, transforming a bitmap into a smooth, scalable image. The input is a bitmap (PBM, PGM, PPM, or BMP format), and the default output is an encapsulated PostScript file (EPS). A typical use is to create EPS files from scanned data, such as company or university logos, handwritten notes, etc. The resulting image is not "jaggy" like a bitmap, but smooth. It can then be rendered at any resolution. potrace can currently produce the following output formats: EPS, PostScript, PDF, SVG (scalable vector graphics), Xfig, Gimppath, and PGM (for easy antialiasing).

  • potracegui
    potracegui is a GUI interface for potrace, a great program for tracing bitmapped images.
  • ppmcaption
    ppmcaption adds text to images. Multiple blocks of text can be placed on the image, with varying fonts, font sizes, colors, and transparency.
    PRICE can open several file formats and apply high quality filters and other enhancements to the image.
  • Qtpfsgui
    Qtpfsgui is a graphical user interface that enables users to work on HDR images. Supported operations include: creations of a HDR file from a set of images of a scene taken at different exposure settings, tone-mapping an HDR image into a common LDR image format (e.g JPEG or PNG), and loading, saving, and rotating existing HDR images. In some ways, the program is a open source clone of Photomatix.
  • QuikKopy
    QuikKopy is an image copying utility written in Perl. It makes use of the graphics library ImageMagick to allow image manipulation to be applied in bulk to multiple images.
  • RPhoto
    RPhoto is a small software aiming at the easy handling of digital camera's photos. Its origin resides in the lack of a simple software capable of cropping photos with a constant ratio, to avoid white borders when printing.
  • Scale2x
    Scale2x is real-time graphics effect able to increase the size of small bitmaps guessing the missing pixels without interpolating pixels and blurring the images. It was originally developed for the AdvanceMAME project in the year 2001 to improve the quality of old games with a low video resolution. Derivative Scale3x and Scale4x effects which scale the image of 3x and 4x are also available.
  • Scan Tailor
    Scan Tailor is an interactive post-processing tool for scanned pages. It performs operations such as page splitting, deskewing, adding/removing borders, and others.
  • SDSC Image Tools

  • SeBIE
    Semi-Batched-Image-Editor: input filename selection via regular expressions, create output filename via regular expression and substitution, select image details with a given proportion, scale to a given output format when saving, and apply some color correction.
  • Simple Image Reducer
    Simple Image Reducer is an GTK application to simple reduce and rotate images. The program can be useful for processing digital photos before sending by e-mail or uploading on the web.
    SINFG is a flexible resolution-independent image manipulation package, which allows you to create a wide variety of images including fractals and vector graphics. It consists primarily of two programs: SINFG Studio and SINFG Tool.
  • SmillaEnlarger
    SmillaEnlarger is an easy-to-use digital photo-enlarger: choose a region of the original image, select a zoom factor (or width/height of the result), and calculate the picture.
  • Stamp
    STAMP is an image time stamp program released under the GNU Public License. It places customizable text messages (such as dates, times, or witty quotes) as color strings onto JPEG images.
  • SVGSlice
    SVGSlice is a plugin for the vector graphics program, Inkscape, which allows a high-quality SVG image to be directly sliced into bitmap graphics for a website. It does this using Inkscape's built-in layers and rectangles, so that you can visually draw where you want slicing to be done, directly from within the program.
  • thumbnail
    thumbnail resizes images down to a maximum of 10,000 pixels (equivalent to a 100x100 image), so that each thumbnail has the same amount of detail, reguardless of its dimensions.
  • Tint Photo Editor

  • VIPS
    VIPS is a free image processing system. It aims to be about half-way between Photoshop and Excel: it is very bad at retouching photographs, but very handy for the many other imaging tasks that programs like Photoshop get used for. It is good with large images (images larger than the amount of RAM in your machine), and for working with colour.
  • VRPE
    VRPE is a small gtk2-gui project to process multiple single image files using ImageMagick, mplayer and transcode.
  • xacte
    An interactive X window program which may be used to create and edit groups of colors.
