ImageMagick is a tool designed to improve the quality of resized images dramatically. It can recognize custom image sizes and also configure image quality or use dynamically computed default value.
With ImageMagick, you can optimize different image sizes for either quality or size, and you can manipulate image files directly from the command line, or access the different manipulation methods through your favorite Perl, C, C++, or Java development environment.
After initialization, ImageMagick welcomes you with a somewhat old-fashioned interface, notwithstanding, it is very well organized and relatable. It also can read and write over two hundred image file formats, including SVG, PDF, Postscript, WebP, EXR, DPX, TIFF, HEIC, GIF, JPEG, and PNG. You can also use it to flip, resize, mirror, shear, rotate, distort and transform images, apply various special effects, adjust image, colors, draw text, lines, polygons, and Bezier curves.
Typically, the functionality of ImageMagick is utilized from the command line. Nevertheless, you can use features from programs written in your preferred language. Here is a host of interfaces from which you can choose: MagickCore (C), G2F (Ada), RMagick (Ruby), MagickWand for PHP (PHP), PascalMagick (Pascal), ChMagickTclMagick (Tcl/TK), PythonMagick (Python), JMagick (Java), MagickNet (.NET) LMagick (Lisp), ImageMagickObject (COM+), Magick++ (C++), (Ch), PerlMagick (Perl), IMagick (PHP), NMagick (Neko/haXe).
ImageMagick is packed with numerous features. It has a ‘format conversion’ feature with which you can convert an image from one format to another, example- PNG to JPEG. You can also flip, crop, and even trim an image. It has a ‘Transparency’ option that enables you to render portions of an image completely invisible. With the ‘draw’ option, you can add shapes or text to an image. The ‘special effects option’ enables you to tint, blur, sharpen as well as threshold any image. From a group of images, you can create a GIF animation sequence using the ‘animation’ feature.
The software also consists of an ‘image identification’ feature that describes the format and attributes of an image, and with the ‘composite’ option, you can overlap one image over another. With the ‘Morphology of shapes,’ you can extract features, describe shapes, and recognize patterns in images. The ‘motion picture’ support helps you to read and write the common image formats used in digital film work. The ‘high dynamic-range images’ accurately represent the vast range of intensity levels found in real scenes, ranging from the brightest direct sunlight to the deepest darkest shadows. Using the ‘virtual pixel support,’ you get convenient access to pixels outside the image region.
Worthy of note is the fact that ImageMagick is thread-safe and most internal algorithms execute in parallel to take advantage of speed-ups offered by multicore processor chips. With ‘heterogeneous distributed processing,’ certain algorithms are OpenCL-enabled to take advantage of speed-ups offered by executing in concert across heterogeneous platforms which consist of GPUs, CPUs and other processors. Using ImageMagick on your iPhone, you can edit, convert, and compose images on your iOS computing device such as the iPhone or iPad.
The software is delivered as a source code which you may freely use, modify, copy as well as distribute in both open and proprietary applications. It is also delivered as a ready-to-run binary distribution. With the ‘large image support,’ it can read, write or process mega-, giga-, or tera-pixel image sizes. You can also encipher and decipher an image, converting ordinary images into unintelligible gibberish and back again. With the ‘Discrete Fourier transform,’ it implements the forward and inward DFT.
Furthermore, it contains an ‘image calculator’ with which you can apply mathematical expressions to an image or image channels. The ‘generalized pixel distortion’ corrects and induces image distortions such as perspective. With the ‘montage’ option, you can juxtapose image thumbnails on an image canvas. Using the ‘decorate’ option, you can add a border or frame to an image. For a smooth setup, you are expected to pay close attention to the additional tasks which you want the application to perform. It is recommended for use by the OSSCC and has been approved by the OSI.
This lightweight image manipulation software provides you with numerous tools to create great images under an intuitive environment. In fact, ImageMagick pushes the envelope with powerful features and simplified workflows that provide creative professionals as well as photographers the freedom to deliver stunning images. Although the interface is quite outdated, it can be accessed via command line.
