ImageMagick: Command-line Tools: Conjure
Author: ImageMagick Studio LLC
Description: ImageMagick (TM) is a free software suite to create, edit and compose bitmap images. It can read, convert and write images in a large variety of formats. Images can be cropped, colors can be changed, various effects can be applied, images can be rotated and combined, and text, lines, polygons, ellipses and Bézier curves can be added to images and stretched and rotated. ImageMagick is free software: it is delivered with full source code and can be freely used, copied, modified and distributed. Its license is compatible with the GPL. It runs on all major operating systems. Most of the functionality of ImageMagick can be used interactively from the command line; more often, however, the features are used from programs written in the programming languages Perl, C, C++, Python, PHP, Ruby or Java, for which ready-made ImageMagick interfaces (PerlMagick, Magick++, PythonMagick, MagickWand for PHP, RubyMagick, and JMagick) are available. This makes it possible to modify or create images automa [cell cut: 1159 characters, first 1000 kept]

The `conjure` program processes a Magick Scripting Language (MSL) script. The Magick scripting language (MSL) will primarily benefit those that want to accomplish custom image processing tasks but do not wish to program, or those that do not have access to a Perl interpreter or a compiler. See Command Line Processing for advice on how to structure your `conjure` command or see below for example usages of the command. ## Example Usage We list a few examples of the `conjure` command here to illustrate its usefulness and ease of use. To get started, here is simple `conjure` command:
      conjure -dimensions 400x400 incantation.msl
Where incantation.msl is our MSL script:
      <?xml version="1.0" encoding="UTF-8"?>
      <image size="400x400" \>
        <read filename="image.gif" />
        <get width="base-width" height="base-height" />
        <resize geometry="%[dimensions]" />
        <get width="width" height="height" />
        <print output="Image sized from %[base-width]x%[base-height] to %[width]x%[height].\n" />
        <write filename="image.png" />
      </image>
You can find additional examples of using `conjure` in Graphics from the Command Line. Further discussion is available in More Graphics from the Command Line and Examples of ImageMagick Usage. ## Option Summary The `conjure` command recognizes these options.
