+  <p>
+    NDFileMagick inherits from NDPluginFile. This plugin saves data in any of the formats
+    supported by the <a href="http://www.graphicsmagick.org/">GraphicsMagick</a> package.
+    GraphicsMagick supports dozens of file formats, including TIFF, JPEG, PNG, PDF,
+    and many others. GraphicsMagick automatically selects the output file format based
+    on the extension of the file (.jpg=JPEG, .tif=TIFF, etc. The GraphicsMagick plugin
+    should be able to write files in any format in the <a href="http://www.graphicsmagick.org/formats.html">
+      list of GraphicsMagick supported file formats"</a> that has a "W" or "RW" in the
+    Mode column.</a>.
+  </p>
+  <p>
+    The GraphicsMagick plugin is limited to 8 and 16-bit integer arrays. It supports
+    color modes Mono and RGB1. NDFileMagick is limited to a single array per file, but
+    capture and stream mode are supported by writing multiple files.
+  </p>
+  <p>
+    The GraphicsMagick plugin supports the Int32 parameter NDFileMagickCompressType
+    to control the compression mode of the file. NDFileMagick.template defines 2 records
+    to support this: $(P)$(R)CompressMode (longout) and $(P)$(R)CompressMode_RBV (longin).
+    The following are the supported compression modes:</p>
+  <ul>
+    <li>"None"</li>
+    <li>"BZip"</li>
+    <li>"FAX"</li>
+    <li>"Group 4"</li>
+    <li>"JPEG"</li>
+    <li>"LZW"</li>
+    <li>"RLE""</li>
+    <li>"Zip"</li>
+  </ul>
+  <p>
+    No formats support all of these compression modes. Many support only one, or have
+    an implicit compression mode and so ignore the CompressMode parameter. For example,
+    the JPEG format supports only the JPEG compression scheme, which is implicit. The
+    TIFF format supports "None", ...</p>

+    The <a href="areaDetectorDoxygenHTML/class_n_d_file_t_i_f_f.html">NDFileNetTIFF class
+      documentation </a>describes this class in detail.
+  </p>
+  <p>
+    The NDFileTIFF plugin is created with the NDFileTIFFConfigure command, either from
+    C/C++ or from the EPICS IOC shell.</p>
+  <pre>NDFileTIFFConfigure (const char *portName, int queueSize, int blockingCallbacks, 
+                     const char *NDArrayPort, int NDArrayAddr, size_t maxMemory,
