Favorite CLI Apps: Imagemagick



Imagemagick is an awesome command-line based image manipulation tool.

[Paraphrased from the imagemagick manual:]

ImageMagick®, is a software suite to create, edit, and compose bitmap images. It can  read,  convert  and  write  images in a variety of formats. Use ImageMagick to translate, flip, mirror, rotate, scale, shear and transform  images, adjust image colors, apply various special effects, or draw text, lines, polygons, ellipses and Bezier curves.  ImageMagick  includes a number of command-line utilities for manipulating images. Most of you are probably accustom to editing images one at a time with a graphical user interface (GUI) with such programs  as gimp or Photoshop. However, a GUI is not always convenient. Suppose you want to process an image dynamically or you want to apply  the  same  operations  to  many images  or  repeat  a  specific  operation at different times to the same or different image. For these types of operations, the command-line image processing utility is appropriate.

To install imagemagick, use Synaptic, or issue the following command in a terminal

sudo aptitude install imagemagick

There are many examples on the imagemagick website.
