Introduction to ImageMagick

ImageMagick (TM) is a free software for creating, editing, and merging images. It can read, convert, and write images in multiple formats. Image cutting, color replacement, application of various effects, image rotation, combination, text, straight line, polygon, elliptic, curve, attached to image stretching and rotation. ImageMagick is a free software: all source code is open and can be freely used, copied, modified, and released. It complies with the GPL license agreement. It can run on most operating systems. Most functions of ImageMagick come from the command line tool.

Generally, it supports the following programming languages: Perl, C, C ++, Python, PHP, Ruby, and Java; ready-made ImageMagick interfaces (perlmagick, magick ++, pythonmagick, magickwand for PHP, rubymagick, and jmagick) are available. This makes it possible to automatically modify and create images dynamically.

ImageMagick supports at least 90 image formats: A, art, Avi, AVS, B, Bie, BMP, BMP 2, bmp3, C, cache, caption, Cin, CIP, clip, clipboard, CMYK, cmyka, cur, cut, DCM, dcx, DNG, Dot, DPS, DPX, EMF, epdf, EPI, EPS, eps2, eps3, EPSF, epsi, EPT, ept2, ept3, fax, fits, fpx, fractal, G, G3, GIF, gif87, gradient, gray, HDF, histogram, htm, HTML, ICB, ICO, icon, jbg, JBIG, jng, JP2, JPC, JPEG, JPG, JPX, K, label, M, m2v, MAP, mat, matte, miff, MNG, Mono, MPC, MPEG, mpg, MSL, MTV, mvg, null, o, OTB, P7, pal, palm, pattern, PBM, PCD, PCDs, PC L, PCT, PCX, PDB, PDF, PFA, pfb, PGM, pgx, Picon, Pict, pix, pjpeg, plasma, PNG, png24, png32, png8, PNM, ppm, preview, PS, ps2, PS3, PSD, ptif, PWP, R, Ras, RGB, rgba, rgbo, RLA, RLE, Scr, SCT, SFW, SGI, shtml, stegano, sun, SVG, svgz, text, TGA, Tif, Tiff, tile, Tim, TTC, TTF, txt, UIL, uyvy, VDA, Vicar, vid, viff, VST, wbmp, WMF, wmfwin32, WMZ, WPG, X, xbm, XC, xcf, XPM, XV, xwd, Y, YCbCr, ycbcra, YUV.

ImageMagick is a stable tool set and development kit that can be used to read, write, and process over 89 basic formats of image files, including popular tiff, JPEG, GIF, and PNG, PDF, photocd, and other formats. With ImageMagick, You can dynamically generate images based on the needs of Web applications. You can also resize, rotate, sharpen, subtract, or add special effects to an image or image sequence, save the operation results in the same format or other formats. Operations on images can be performed through the command line or through C/C ++, Perl, Java, PHP, Python or Ruby programming. At the same time, ImageMagick provides a high-quality 2D toolkit that partially supports SVG. Currently, imagemagic focuses on performance, bug reduction, and stable API and Abi. ImageMagick is powerful but free of charge.

ImageMagick has the following functions:
1) convert an image from one format to another
2) resize, rotate, sharpen (Sharpen), reduce colors, image effects
3) The compositing image of the thumbnail (a montage of image thumbnails)
4) Transparent images for Web backgrounds
5) make a group of images into GIF Animation
6) Make a combination of several images
7) write or draw a picture on an image
8) Add a border or frame to the image
9) obtain some image features
