<pclass="lead magick-description">ImageMagick uses an ASCII string known as <var>convert</var> (e.g. <code>GIF</code>) to identify file formats, algorithms acting as formats, built-in patterns, and embedded profile types. Support for some of the formats are delegated to libraries or external programs. The Installation Guide describes where to find these distributions and any special configuration options required.</p>
<p>To get a complete listing of which image formats are supported on your system, type</p>
<preclass="highlight"><code>identify -list format
</code></pre>
<p>On some platforms, ImageMagick automagically processes these extensions: .gz for Zip compression, .Z for Unix compression, .bz2 for block compression, and .pgp for PGP encryption. For example, a PNM image called image.pnm.gz is automagically uncompressed.</p>
<h2><aclass="anchor"id="colorspace"></a>A Word about Colorspaces</h2>
<p>A majority of the image formats assume an sRGB
colorspace (e.g. JPEG, PNG, etc.). A few support only linear RGB (e.g. EXR,
DPX, CIN, HDR) or only linear GRAY (e.g. PGM). A few formats support CMYK.
Then there is the occasional format that also supports LAB (that is CieLAB)
(e.g. TIFF, PSD, JPG, JP2). To determine the colorspace of your image, use

<p>ImageMagick supports a number of image format specifications which refer to images prepared via an algorithm, or input/output targets. The following table lists these pseudo-image formats:</p>
<td>Image sequence laid out in continuous irregular courses</td>
<td>By default, a reasonable canvas size and border width is determined relative to the image collection you provide. You can explicitedly set the canvas size and border width by appending to the filename, e.g. <code>ashlar:canvas.png[1024x768+4+4]</code>. By default, alignment is along the left edge. Use <code>-define ashlar:best-fit=true</code> to align on both the left and right edges. You can label the image tiles with, for example, <code>-label %f</code>.</td>
