%  PROGRAM
% putzoom - Non-Interactive Display of a Zoom Image
%
%  DESCRIPTION
% Putzoom is a visualization program that displays a "zoomed" image, or
% a close-up of a region of interest in an image.
% 
% The input file containing the data to be displayed as a zoom is
% monitored by default; the file is checked every 2 seconds for change,
% and if it has been modified, the zoom display is updated accordingly.
% The interval at which the input file is checked for modification may
% be specified using the [-update] argument.
% 
% A clip mask may be used to dictate the portion of the data that is
% displayed using the [-clip] argument.  For more information of using
% clip masks, see Chapter 4 on Editimage.
% 
% An alternate input color map may be used to change the current color map
% using the [-cmap] argument.
% 
% The x and y coordinates that specify where the zoomed image focuses
% within the source image can be expressed using the [-zoomx] and
% [-zoomy] arguments.
% 
% It is possible to specify the zoom factor using the [-zoomfactor]
% argument.  When the zoom factor takes on values greater than one, the 
% object is "zoomed in" and when the zoom factor takes on values less
% than one, the object is "zoomed out".  For example, a value of 2.0 doubles the
% size of the image, while a value of 0.5 shrinks the image by half.  The zoom 
% factor is intentionally a double precision value; this means that in the case 
% of pixel replication, pixels are rounded to their nearest location.  This also 
% implies that under certain circumstances, the zoom will not appear to stretch 
% evenly over the entire image.
% 
% By default, the visualization display will share its colormap with all
% other applications running at the same time; that is, it does not not
% use a private colormap, but rather makes use of the default
% colormap.  It is possible to specify that the visualization display
% allocate its own private colormap or "grab" all available colors for
% its own use.  This is done using the [-priv] argument.  When [-priv]
% is specified, moving the mouse pointer into the display window will
% cause the display to have its private colormap installed; moving the
% pointer out of the display window will cause the private colormap to
% be de-installed.  This results in the "technoflashing" phenomenon
% characteristic of colormap switching.
% 
% Color allocation can also be controlled and set to either
% .I "read-only"
% or
% .I "read/write"
% using the [-alloc] argument.  When set to
% .I "read-only",
% once a color cell has been allocated, it can have its color set only once;
% from then on, the color cell can be shared by multiple applications, but
% not changed.  If the visualization display requires the color displayed
% to change, it must re-allocate the color cell, forcing a re-display of
% data.  This can be an expensive procedure.  In contrast, after a
% .I "read/write"
% color cell is allocated, it can have its color changed at any time
% without re-allocation; the data being displayed does not need to be
% redisplayed, and the color update process is much more efficient.
% However, the colors used in the visualization display cannot be shared by
% other applications.
% 
% On creation, the zoom display window may be placed manually (the
% default method), or placed automatically.  For automatic placement
% of the zoom window, specify the desired location in device (screen)
% coordinates using the [-x] and [-y] arguments.
% 
% While the zoom display window should be created with a default size
% that is appropriate to display the data, a width and height for the
% window can be specified explicitly using the [-width] and [-height]
% arguments.  Note that interactive resizing of the image display
% window using the window manager is currently NOT supported.
