244 <h1>ImageMagick Stream Command-line Tool</h1>
245 <p class="navigation-index">[<a href="#usage">Example Usage</a> • <a href="#options">Option Summary</a>]</p>
247 <div class="doc-section">
248 <p><kbd>Stream</kbd> is a lightweight tool to stream one or more pixel components of the image or portion of the image to your choice of storage formats. It writes the pixel components as they are read from the input image a row at a time making <kbd>stream</kbd> desirable when working with large images or when you require raw pixel components.</p>
251 <h2><a id="usage"></a>Example Usage</h2>
252 <div class="doc-section">
254 <p>We list a few examples of the <kbd>stream</kbd> command here to illustrate its usefulness and ease of use. To get started, lets stream the red, green, blue components of a 640x480 JPEG image to disk as unsigned characters:</p>
256 <p class='crt'><span class="crtprompt"> $ </span><span class='crtin'>stream -map rgb -storage-type char image.jpg pixels.dat</span><span class='crtout'></span><span class="crtprompt"> $ </span><span class='crtin'>display -depth 8 -size 640x480 rgb:pixels.dat</span></p>
257 <p>Here we extract a 100x100 region from a TIFF image in the grayscale format as doubles:</p>
259 <p class='crt'><span class="crtprompt"> $ </span><span class='crtin'>stream -map i -storage-type double -extract 100x100+30+40 image.tif gray.raw</span></p>
260 <p>You can also associate the region to extract with the image filename:</p>
262 <p class='crt'><span class="crtprompt"> $ </span><span class='crtin'>stream -map i -storage-type double 'image.tif[100x100+30+40]' gray.raw</span></p>
265 <h2><a id="options"></a>Option Summary</h2>
266 <div class="doc-section">
