BEFORE YOU BEGIN
Please read the README.FIRST file - found at the root level of this server -
for general information and instructions on unarchiving and uncompressing
files (files with the ".sit", ".hqx", ".zip", ".tar", and ".Z" extensions).
The README.BROCHURE also contains helpful descriptions of this and other
software offered on the ftp server.

NCSA PALEDIT
NCSA PalEdit is a tool for the creation and customizing of color palettes that
may be used with other NCSA software such as NCSA Image. With PalEdit, you can
modify the whole palette or intervals in the palette, to create a set of colors
tailored to your needs.
REQUIREMENTS
To run NCSA PalEdit, you must have a Macintosh with color hardware
capable of displaying 256 colors simultaneously. You also must have
System software version 6.0.2 or later installed on the machine.
NEW FEATURES
New features in the tool panel of NCSA PalEdit version 2.0 include
interval manipulation tools that allows you to make range selections
in the palette and component plot simultaneously, and an
interpolation tool, which interpolates across the current palette
interval.
Moreover, several tools and commands that used to solely modify a
range of the palette now modify intervals of the palette/plot.
As in NCSA PalEdit 1.2, you can also:
Load and modify existing palettes
Create and customize new palettes
Save new or modified palettes in the following file formats:
raw palette
HDF
Klutz DA
Canvas
PixelPaint
Use any combination of four color models - RGB, CMY, HSV, and
HSL
Adjust the individual color components of any of the four color
models
Select and modify regions of interest
Rotate color entries in the palette in either direction
Change the color of an individual color entry using the color
wheel dialog box
Copy and paste palettes from NCSA PalEdit into other
applications, such as NCSA DataScope, NCSA Image, NCSA ImageIP,
NCSA Layout, and NCSA GelReader
