ImageMagickImageMagick — набор программ для чтения и редактирования файлов множества графических форматов. Является свободным и кроссплатформенным программным обеспечением.
Use ImageMagick® to create, edit, compose, or convert bitmap images. It can read and write images in a variety of formats (over 200) including PNG, JPEG, GIF, HEIC, TIFF, DPX, EXR, WebP, Postscript, PDF, and SVG. ImageMagick can resize, flip, mirror, rotate, distort, shear and transform images, adjust image colors, apply various special effects, or draw text, lines, polygons, ellipses and Bézier curves.
Features and Capabilities
Here are just a few of what ImageMagick can do for you:
create a GIF animation sequence from a group of images. accurate color management with color profiles or in lieu of-- built-in gamma compression or expansion as demanded by the colorspace. force all pixels in the color range to white otherwise black. utilize ImageMagick from the command-line. bidirectional text support and shaping. overlap one image over another. uniquely label connected regions in an image. smallest area convex polygon containing the image foreground objects. In addition, the minimum bounding box and unrotate angle are also generated. add a border or frame to an image. , . implements the forward and inverse. offload intermediate pixel storage to one or more remote servers. add shapes or text to an image. convert ordinary images into unintelligible gibberish and back again. convert an image from oneto another (e.g. PNG to JPEG). correct for, or induce image distortions including perspective. certain algorithms are-enabled to take advantage of speed-ups offered by executing in concert across heterogeneous platforms consisting of CPUs, GPUs, and other processors. accurately represent the wide range of intensity levels found in real scenes ranging from the brightest direct sunlight to the deepest darkest shadows. Use adaptive histogram equalization to improve contrast in images. apply a mathematical expression to an image, image sequence, or image channels. create a gradual blend of two colors whose shape is horizontal, vertical, circular, or elliptical. describe the format and attributes of an image. convert, edit, or compose images on yourdevice such as the iPhone or iPad. read, process, or write mega-, giga-, or tera-pixel image sizes. juxtapose image thumbnails on an image canvas. extract features, describe shapes, and recognize patterns in images. read and write the common image formats used in digital film work. , . map visually identical images to the same or similar hash-- useful in image retrieval, authentication, indexing, or copy detection as well as digital watermarking. blur, sharpen, threshold, or tint an image. insert descriptive or artistic text in an image. ImageMagick is thread safe and most internal algorithms execute into take advantage of speed-ups offered by multicore processor chips. resize, rotate, deskew, crop, flip or trim an image. render portions of an image invisible. convenient access to pixels outside the image boundaries.
