ImageMagick is a software suite to create, edit, compose, or convert bitmap images.
It can read and write images in many different formats (over 100) including DPX, EXR, GIF, JPEG, JPEG-2000, PDF, PNG, Postscript, SVG, and TIFF. Use ImageMagick
to resize, flip, mirror, rotate, distort, shear and transform images, adjust image colors, apply various special effects, or draw text, lines, polygons, ellipses and Bzier curves.
The functionality of ImageMagick
is normally used from the command line or you also can use the features from programs written in your favorite language. With a language interface, use ImageMagick
to modify or create images dynamically and automagically.
Download and install ImageMagick
safely and without concerns.
ImageMagick highlights and features:
Format conversion: convert an image from one format to another (e.g. PNG to JPEG).
Transform: resize, rotate, crop, turn or cut an image.
Transparency: render portions of an image undetectable.
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 & comments: insert illustrative or artistic text in an image.
Image identification: describe the format and characteristics of an image.
Composite: overlap one image over another.
Montage: juxtapose image thumbnails on an image canvas.
Generalized pixel distortion: correct for, or induce image distorted shapes including perspective.
Morphology of shapes: extract features, describe shapes, and recognize patterns in images.
Delineate image features: Canny edge detection, mean-shift, Hough lines.
Motion picture support: read and write the common image formats used in digital movie work.
Image calculator: apply a mathematical expression to an image or image channels.
Connected component labeling: uniquely label connected regions in an image.
Discrete Fourier transform: implements the forward and inverse DFT.
Perceptual hash: map visually identical images to the same or similar hash-- useful in image retrieval, authentication, indexing, or copy detection together with digital watermarking.
Color management: precise color management with color profiles or in lieu of-- built-in gamma compression or expansion as demanded by the colorspace.
High dynamic-range images: accurately represent the wide range of intensity levels found in real scenes that range 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 execute in parallel to take good advantage of speed-ups offered by multicore processor chips.
Distributed pixel cache: offload intermediate pixel storage to one or more remote servers.
Heterogeneous distributed processing: certain algorithms are OpenCL-empowered to make the most of speed-ups offered by executing in concert across heterogeneous platforms consisting of CPUs, GPUs, and other central processing units.
ImageMagick on the iPhone: convert, edit, or compose images on your own iOS device for example the iPhone or iPad.
