<p class="lead">The <code>identify</code> program describes the format and characteristics of one or more image files. It also reports if an image is incomplete or corrupt. The information returned includes the image number, the file name, the width and height of the image, whether the image is colormapped or not, the number of colors in the image, the number of bytes in the image, the format of the image (JPEG, PNM, etc.), and finally the number of seconds it took to read and process the image.  Many more attributes are available with the verbose option.  See <a href="command-line-processing.html">Command Line Processing</a> for advice on how to structure your <code>identify</code> command or see below for example usages of the command.</p>

<h2><a class="anchor" id="usage"></a>Example Usage</h2>

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

<pre class="bg-light text-dark mx-4"><code>-> identify rose.jpg
rose.jpg JPEG 70x46 70x46+0+0 8-bit sRGB 2.36KB 0.000u 0:00.000
</code></pre>

<p>By default, <code>identify</code> provides the following output:</p>

<ul><code>Filename[frame #] image-format widthxheight page-widthxpage-height+x-offset+y-offset colorspace user-time elapsed-time</code></ul>

<p>Next, we look at the same image in greater detail:</p>

<p>Note, the image signature is generated from the pixel components, not the ima
ge metadata.</p>


<p>To get the print size in inches of an image at 72 DPI, use:</p>

<pre class="bg-light text-dark mx-4"><code>-> identify -format "%[fx:w/72] by %[fx:h/72] inches" document.png
8.5 x 11 inches
</code></pre>

<p>The depth and dimensions of a raw image must be specified on the command line:</p>

<pre class="bg-light text-dark mx-4"><code>-> identify -depth 8 -size 640x480 image.raw
image.raw RGB 640x480 sRGB 9kb 0.000u 0:01
</code></pre>

<p>Here we display the image texture features, moments, perceptual hash, and the number of unique colors in the image:</p>

<pre class="bg-light text-dark mx-4"><code>-> identify -verbose -features 1 -moments -unique image.png
</code></pre>

<p>Here is a special define that outputs the location of the minimum or maximum pixel of the image:</p>

<pre class="bg-light text-dark mx-4"><code>identify -precision 5 -define identify:locate=maximum -define identify:limit=3 image.png
</code></pre>

<p>You can find additional examples of using <code>identify</code> in <a href=".https://legacy.imagemagick.org/Usage/">Examples of ImageMagick Usage</a>.</p>

<h2><a class="anchor" id="options"></a>Option Summary</h2>
