.LP
The \fIInput\fP subform allows to specify an input imagery file,
an input elevation file, or a colormap file.
.sp
.IP "1)  Khoros image file with data to be used as IMAGERY:"
Each time you fills in this input file parameter box 
and hit the <cr> key, the new imagery data will be displayed, draped
over the elevation data, when the elevation data is displayed as either
color mesh or as a surface plot.  Remember that you should ONLY use VIFF
images that have the same number of rows and columns as the elevation data.
With multiband images, the first band is displayed by default.  The CHANGE 
BANDS option on the "Display Utilities" 
pull-down menu can be used to display other bands if desired.  Note that 
if any new colormap has been previously input (see below), it will be 
over-written at this time by the colormap of the new input image.  
.sp
.IP "2)  Khoros image file with data to be used as ELEVATION:"
Each time you fills in this input file parameter box
and hit the <cr> key, the new elevation data will be plotted.
Remember that you should ONLY use VIFF
images that have the same number of rows and columns as the imagery data.
With multiband images, the first band is displayed by default.
.sp
.IP "3) Khoros Image File with COLORMAP to be Used:"
This feature allows one to assign a different colormap 
to the imagery data that is displayed when the color mesh or surface plot
types are used.  Each time you fill in this parameter box and 
and hit the <cr> key, the new colormap is installed for the current imagery.  
To restore the original colormap, the original viff file to provide the 
imagery data must be re-entered in this parameter box. 
.sp
.IP "4) OUTPUT image filename:"
If you would like to make a screen dump of the imagery and elevation data
that is currently displayed, enter the desired filename here and hit
<cr>.  Wait for a moment while the output mechanism works.  A VIFF image will 
be created from the current contents of the \fBviewimage\fP workspace.  A pop-up
form will let you know when the output image has been created.
