- About NCSA ImageTool
-
- NCSA ImageTool is a utility that provides a variety of methods for
- visualizing a set of data points. Color images, contour plots, 3D
- plots, and XY graphs are mechanisms that you employ to "see" the
- data. Contour plots, 3D plots, and XY graphs can be printed. Color
- images can be magnified, composited, and, to some degree, edited.
- You can modify color palettes and save them. You can also save
- individual images or selected portions of the canvas.
-
-
- New Features in NCSA ImageTool 1.1
-
- NCSA ImageTool 1.1 now allows you to load and manipulate HDF
- (Hierarchical Data Format) files. Consequently, with HDF
- support you can open HDF files from or transfer them to other
- NCSA software.
-
- You'll notice a few new option in the NCSA ImageTool screen. One
- of these options, "Image Loading," requires you to specify the type
- of file you are loading. The other option, "SDS scaling," requires
- that you enter your file dimensions (unless you're opening an
- HDF file which includes its dimensions.)
-
- Finally, NCSA programmers have fixed many bugs, added error
- messages, and cleaned up the format and text of the first version.
-
-
- System Requirements
-
- In order to run NCSA ImageTool, you must have a Sun
- Workstation with color hardware capable of displaying 256 colors
- simultaneously. You must also have SunView installed on the
- machine.
- Use of This Manual
-
- This section describes the organization of this manual and the
- conventions and nomenclature used in developing it. Before using
- NCSA ImageTool, you should be familiar with the SunView user
- interface and know how to use control buttons, the mouse, and
- scroll bars. If you have not used the Sun Workstation before, refer
- to the owner's guide that came with your Sun Workstation before
- using this package.

- Form of Presentation
- The material in this manual is presented in text, screen displays,
- or command line notation.

- Text
- In explaining various features and commands, this manual often
- presents a word within a paragraph in italics to indicate that the
- word is defined within the paragraph, or that it is a significant
- term that should be noted and/or is being mentioned for the first
- time.
-
- Portions of this manual refer to other sections of the manual which
- explain related topics. These cross references usually mention the
- title of sections or chapters enclosed in quotation marks, such as,
- See Chapter 1, "Using Composite Tool."

- Command Line Format Notation
- Throughout this manual, many explanations instruct you to make
- entries by typing on the keyboard. These entry instructions are
- printed in courier bold type and appear within a paragraph
- or on a separate line. The command lines in this manual are
- normally shown in lowercase, except in rare instances where
- uppercase is required.
-
- When it is necessary for you to press a key that is labeled with
- more than one character (such as the RETURN key), this manual
- identifies the key with all capital (uppercase) letters. Keys to be
- entered are printed in bold type. Keys that are pressed
- simultaneously or in succession are linked with a hyphen. For
- example, press CONTROL-A.
