.PP
Through the "Image Utilities" pull-down menu, five of \fBeditimage\fP's subforms
can be accessed.  These subforms deal with input & output, regions of interest,
colormaps, annotations, and miscellaneous image operations.
.SH
1) Input/Output
.PP
The first subform, "Input/Output", provides I/O capabilities for 
\fBeditimage\fP.
Global input and output directories may be set using this subform.  
A new image may be input and displayed.  An image may be input so that the 
currently-displayed image may use the new image's colormap. An image
may be provided to act as a clip mask or a shape mask.  An image may be
overlaid onto the currently displayed image. Finally, 
images may be output from the "Input/Output" subform.
.SH
2) Region of Interest 
.PP
The second subform, "Region of Interest", deals with region of 
interest operations.  
Such operations are useful for executing image processing routines on
particular regions of an image.  
Using ROI functions, one is able to extract regions of an image, insert 
subimages into an image, and execute image processing routines 
on the region of interest.
Regions of interest can be defined either by mouse or by keyboard.
.PP
If the image has been converted in order to be displayed, ROI image processing 
routines will operate on the \fIconverted\fP image data.  Also, in order for
the image processing routines to use any colormap changes that have been made,
the image must first be saved and then that new image used for 
ROI manipulations.
.sp
Warning: Application of image processing routines to a ROI voids all prior 
colormap operations, therefore the image should first be saved, 
otherwise the changes will be lost during this operation.  This occurs because
RIO operations can create pixels with unknown LUT or colormap values, 
therefore the entire image is mapped according to a linear LUT.
.SH
3) Colormaps
.PP
The third subform, "Colormaps", contains standard colormaps through which
the image pixel values can be automatically mapped.  Color can be changed 
using the following color schemes:
.IP 
RGB Cube
.br
RGB Triangle
.br
RGB Spiral (not available)
.br
RGB Distance
.br
CIE Diagram
.br
Density Slice
.br
Greyscale
.br
Original Colormap
.br
Rainbow
.br
Invert
.br
Random
.LP
"Comment"
.SH
4) Annotations
.PP
The fourth subform, "Annotations", allows the user to add text, lines,
circles, rectangles, or polygons to the displayed image.  Once created,
objects may be deleted, copied, raised or lowered.  Using the 
\fICOMBINE ANNOTATIONS\fP action button found on the "Image Utilities" 
pulldown menu, annotations may actually be made part of the displayed image.
.SH 
4) Comment
.PP
This subform may also be used to create or modify the comment on the 
image header of the currently displayed image.
.sp 2
.SH
IMAGE INFO
.PP
You may obtain information about the currently displayed image by using
this button.
.SH
.sp 2
COMBINE ANNOTATIONS
.PP
If any annotations have been put onto the image using the "Annotations"
subform, this button allows the user to actually make the annotations part
of the image.  Note that if an image with annotations is written out \fIwithout
using the COMBINE ANNOTATIONS button\fP, the annotations will be lost!
