It can read, convert and write images in a variety of formats (about 100) including DPX, GIF, JPEG, JPEG-2000, PDF, PhotoCD, PNG, Postscript, SVG, and TIFF. Use ImageMagick to translate, flip, mirror, rotate, scale, shear and transform images, adjust image colors, apply various special effects, or draw text, lines, polygons, ellipses and Bézierr curves.
Most of the functionality of ImageMagick can be used interactively from the command line.
