Digital Picture Editor – ImageMagick

We had earlier covered several free photo editors here. Today we cover yet another free and open source Digital Picture Editor called ImageMagick. This a is an excellent image editor that can be used to perform magical operations such as creating images from scratch, changing colors, stretching, rotating, overlaying images and overlaying text on images.

ImageMagick is a free photo editing software distributed as a ready-to-run binary and its functionalities are typically utilized from the command line. ImageMagick includes a number of command-line utilities for manipulating images. though command line interface may not be as user friendly as a graphical user interface (GUI) offered by programs such as gimp or Photoshop, command line interfaces are convenient than GUI in certain situations. For example,if you want to process an image dynamically from a web script 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, the command-line image processing utility will be more appropriate.

Find below a list of command line tools bundled with ImageMagick:

  • Animate – Animate an image sequence on any X server.
  • compare – Mathematically and visually annotate the difference between an image and its reconstruction.
  • Composite – overlap one image over another.
  • Conjure – Interpret and execute scripts written in the Magick Scripting Language (MSL).
  • Convert – An image converter tool that can be used to convert between image formats as well as resize an image, blur, crop, despeckle, dither, draw on, flip, join, re-sample, and much more.
  • Display – Image viewer tool to display an image or image sequence on any X server.
  • Identify – Describe the format and characteristics of one or more image files.
  • Import – A screen capture tool to save any visible window on an X server and outputs it as an image file. You can capture a single window, the entire screen, or any rectangular portion of the screen.
  • Mogrify – An ultimate image editing tool to resize an image, blur, crop, despeckle, dither, draw on, flip, join, re-sample, and much more. Mogrify overwrites the original image file, whereas, convert writes to a different image file.
  • Montage – create a photo montage by combining several separate images. The images are tiled on the composite image and can optionally be adorned with a border, frame, image name, and more.
  • Stream – A lightweight tool to stream one or more pixel components of the image or portion of the image to your choice of storage formats. It writes the pixel components as they are read from the input image a row at a time making stream desirable when working with large images or when you require raw pixel components.

Apart from the command line utilities described above, ImageMagick also includes a number of readymade interfaces written in several different languages.You can choose any of the following interfaces to modify or create images dynamically and automagically:

  • G2F (Ada),
  • MagickCore (C),
  • MagickWand (C),
  • ChMagick (Ch),
  • ImageMagickObject (COM+),
  • Magick++ (C++),
  • JMagick (Java),
  • L-Magick (Lisp),
  • NMagick (Neko/haXe),
  • MagickNet (.NET),
  • PascalMagick (Pascal),
  • PerlMagick (Perl),
  • MagickWand for PHP (PHP),
  • IMagick (PHP),
  • PythonMagick (Python),
  • RMagick (Ruby) and
  • TclMagick (Tcl/TK)
  • Format conversion: convert an image from one format to another (e.g. PNG to JPEG)
  • Transform: resize, rotate, crop, flip or trim an image
  • Transparency: render portions of an image invisible
  • Draw: add shapes or text to an image
  • Decorate: add a border or frame to an image
  • Special effects: blur, sharpen, threshold, or tint an image
  • Animation: create a GIF animation sequence from a group of images
  • Text and comments: insert descriptive or artistic text in an image
  • Image identification: describe the format and properties of an image
  • Composite: overlap one image over another
  • Photo Montage: juxtapose image thumbnails on an image canvas
  • Motion picture support: read and write the common image formats used in digital film work
  • Image calculator: apply a mathematical expression to an image or image channels
  • Discrete Fourier transform: implements the forward and inverse DFT.
  • High dynamic-range images: accurately represent the wide range of intensity levels found in real scenes ranging from the brightest direct sunlight to the deepest darkest shadows
  • Encipher or decipher an image: convert ordinary images into unintelligible gibberish and back again
  • Virtual pixel support: convenient access to pixels outside the image region
  • Large image support: read, process, or write mega-, giga-, or tera-pixel image sizes
  • Threads of execution support: ImageMagick is thread safe and most internal algorithms are OpenMP-enabled to take advantage of speed-ups offered by the dual and quad-core processor technologies
  • Heterogeneous distributed processing: certain algorithms get a speed boost by executing in concert across heterogeneous platforms consisting of CPUs, GPUs, and other processors (in development).

ImageMagick runs on all recent Windows releases. It is also available for unix and Mac. Free download imagemagick from here and enjoy the free picture editor.
