+ ~~~~~~~
+
+Overview
+--------
+
+MedJava is a prototype of a large scale distributed medical imaging
+system. It has been developed using Java, in particular, several
+components of Java ACE.
+
+Here are the key features of the MedJava toolkit:
+
+* Images can be both downloaded and uploaded across the network.
+* Images can be uploaded to Web servers that support HTTP PUT
+ functionality (for example, JAWS).
+* The tool contains more than a dozen image filters to do image
+ processing.
+* The image filters can be configured into the system dynamically
+ using the Service Configurator pattern.
+
+Please send comments/suggestions to Prashant Jain (pjain@cs.wustl.edu).

+Getting Started
+---------------
+
+MedJava applet can be configured with several (optional) parameters
+via the HTML file from which the applet is invoked. Here is a list of
+the parameters:
+
+Note:
+ 1) * indicates test-mode parameters
+ 2) All Default URLs begin with
+ http://www.cs.wustl.edu/~pjain/java/ACE_wrappers/java/ImageProcessing/framework/

+Menu
+----
+
+o Open URL
+
+ Allows user to specify a URL. If the URL points to an image that is
+ readable, then the image is downloaded and displayed in the view
+ panel.
+
+ If the URL points to a directory that is readable then a window
+ appears displaying a list of files in that directory. The user can
+ then click on an image file in this window to fetch an image.
+
+ IMPORTANT NOTE: If the URL points to a directory, the directory must
+ not contain an "index.html" file! If it does, the
+ query will fail and no list of files will appear.
+
+o Save
+
+ Allows user to specify a URL to save the currently loaded image to.
+ All images are saved in GIF format. Note that saving/uploading a
+ file can take a while depending upon the size of the image. This is
+ because, the tool first generates the GIF format and then sends the
+ bytes across the network.
+
+ IMPORTANT NOTE: The Web server must support image uploading, that is
+ HTTP PUT functionality. Also, due to applet
+ restrictions, the server MUST be running on the same
+ host from which the applet was downloaded from.
+
+o Reset
+
+ Resets the image to the original. Note that the effects of any
+ filters that were applied to the image will be lost.
+
+o Reload Filters
+
+ Reads the filter configuration file again and reloads all the image
+ filters. Note that this serves as the trigger of the Service
+ Configurator pattern allowing the tool to reconfigure based on new
+ configuration information.
+
+ The filters are specified in filter.conf. To add/remove filters,
+ change this file and then select "Reload Filters".
+
+ To specify a different configuration file, please see "Getting Started".
+
+o Zoom In
+
+ Zooms in to the currently displayed image. Note that the applet only
+ allows to zoom in 4 x times.
+
+o Zoom Out
+
+ Zooms out of the currently displayed image. Note that the applet
+ only allows to zoom out 1/4 x times.
+
+o Apply
+
+ Apply the currently selected filter. By default no filter is
+ selected. Note that applying a filter to an image can taken
+ anywhere between a few seconds to a few minutes depending upon the
+ image size, the filter type, and the speed of the machine on which
+ the applet is running.
+
+o Filters:
+
+ Allows the user to select a filter from the ones that have been
+ configured into the applet. Note that this is a choice menu and its
+ entries depend upon the filters that were specified in the filter
+ configuration file.
+
+ For more information, on how to specify the filters, please see
+ "Getting Started".
+
+o About
+
+ Displays the "About" dialog containing the version of the MedJava
+ applet.
+
+o Help
+
+ Displays this window
