| 16 | <meta name="Description" content="ImageMagick® is a software suite to create, edit, and compose bitmap images. It can read, convert and write images in a variety of formats (about 100) including GIF, JPEG, JPEG-2000, PNG, PDF, PhotoCD, TIFF, and DPX. 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 Bézier curves. ImageMagick is free software delivered as a ready-to-run binary distribution or as source code that you can freely use, copy, modify, and distribute. Its license is compatible with the GPL. It runs on all major operating systems. The functionality of ImageMagick is typically utilized from the command line or you can use the features from programs written in your favorite programming language. Choose from these interfaces: MagickCore (C), MagickWand (C), ChMagick (Ch), Magick++ (C++), JMagick (Java), L-Magick (Lisp), PascalMagick (Pascal), PerlMagick (Perl), MagickWand for PHP (PHP), PythonMagick (Python), RMagick (Ruby), or TclMagick (Tcl/TK). With a language interface, use ImageMagick to modify or create images automagically and dynamically."/> |

| 109 | <p>We list a few examples of the <kbd>display</kbd> command here to illustrate its usefulness and ease of use. To get started, lets display an image in the JPEG format:</p> |

| 111 | <pre class="text"> |
|---|
| 112 | display rose.jpg |
|---|
| 113 | </pre> |

| 115 | <p>To tile a slate texture onto the root window, use:</p> |
|---|
| 116 | |
|---|
| 117 | <pre class="text"> |
|---|
| 118 | display -size 1280x1024 -window root slate.png |
|---|
| 119 | </pre> |
|---|
| 120 | |
|---|
| 121 | <p>To display a visual image directory of all your JPEG images, use:</p> |
|---|
| 122 | |
|---|
| 123 | <pre class="text"> |
|---|
| 124 | display âvid:*.jpgâ |
|---|
| 125 | </pre> |
