.br
        -src  input source image (infile)
.br
        [-target]  input target image (infile)
.br
        [-tp_mode]  selection type
.br
                1  (Select Source & Target),
.br
                or 2  (Select Source Only)
.br
               [default = 1]
.sp
        [-V] Gives the version for warpimage
.br
        [-U] Gives the usage for warpimage
.br
        [-P] Prompts for command line options
.br
        [-A [file1]] Creates the answer file called warpimage.ans or file1
.br
        [-a [file1]] Uses warpimage.ans or file1 as the answer file
.sp 2
.IP "-src {input source image}:"
This is the source image on which tiepoints will be set with \fIwarpimage\fP.
It must be specified as "-src filename", where the file provided is a
Khoros VIFF file.  The VIFF file may be of any data type except complex.
With multiband images, the first band is displayed.  At this time, there
is no capability for changing bands.
.IP "[-target {input target image}]:"
This is the target image on which tiepoints will be set and matched with
their partners on the source image.  Like the source image, it must be 
specified as "-target filename", where the file provided is a Khoros VIFF file. 
The VIFF file may be of any data type except complex.
.IP "[-tp_mode {tiepoint mode}]":
\fIWarpimage\fP may be used in one of two ways. 
Commonly, one creates pairs of tiepoints, one on the source image, matched 
with one on the target image.  
Another approach is to mark tiepoints on the source image only 
(in which case, one shouldn't bother inputting a target image). 
Specify (1) to use the first method, (2) to use the second.  
The [-tp_mode] flag controls which of these methods will be used, \fIthroughout
the entire execution of warpimage\fP.  
.PP
.IP "Version"
The "-V" argument will print out the current version of warpimage.
.IP "Usage"
The "-U" argument will print out the usage for warpimage, in much less
detail than is given here.
.IP "Interactive Prompting"
The "-P" argument will give interactive prompting for each of the arguments
listed above.
.IP "Creating an Answer file"
The "-A [filename]" argument will create an answer file named "filename" if
the filename option is specified, or named "warpimage.ans" if no filename
is given.  An answer file stores the values specified of all arguments listed
above.  Note: the "-A" argument is usually used in conjunction with the "-P"
argument.
.IP "Using an Answer file"
The "-a [filename]" argument will use the answer file named "filename"
if the filename option is specified, or named "warpimage.ans" if no filename
is given.  \fIWarpimage\fP will use the answer file to get values for all
arguments listed above.  No other arguments should be necessary when the "-a"
argument is used.
