IMViz Version
1.0.4
IMViz is a tool for visual data analysis built at NCSA with original support
from the NSF/ARPA Grand Challenge project in Radio Astronomy
Imaging, and subsequent investment by NCSA. IMViz is a
tool for two-dimensional visualization and relies on Motif and
Xlib for its user interface and drawing capabilities.
IMViz 1.0.4 beta binaries are available for
Intel based Linux and Max OS X systems.
Included below is a listing of the major IMViz
features. Also available are download
instructions, the User's Guide to
IMViz, and information about the people who are building IMViz.
However, a number of internal changes
have been made that may have affected its stability.

IMViz
features:
- Easy to use graphical user interface.
- Input of FITS image files (including blanked pixels).
- FITS image files are not read into main memory (i.e.,
such files are memory-mapped), enabling large files to
be displayed and explored. However, IMViz's
operations and graphics do require a reasonably
sized machine, with "reasonable" amounts of
memory and swap space.
- IMViz can read MIRIAD image files.
- Display of 2D images, and display of any orthogonal
2D slice from a 3D cube. For example, from the 3D image
cube with dimensions RA, DEC, and VELOCITY, display RA
vs. DEC for a given VELOCITY.
- Interactive display of pixel coordinates, world
coordinates (e.g. RA and Dec), and data values as the
mouse cursor is moved around the image.
- Interactive vector (line drawing) plots of data value
vs. coordinate value, e.g., for plots of line profile
plots or intensity vs. spatial position.
- Interactive specification of rectangular subregions
and magnified display of subregions.
- Image scaling (by pixel replication or subsampling).
- Support for display of multiple images
simultaneously.
- Animated sweeping through slices along any dimension.
- Synchronized sweeping for multiple data cubes. That
is, the corresponding slices of each data cube are
displayed during the animated sweep. Synchronized
picking, for simultaneous display of data values,
subregions in multiple data sets, or profiles from
multiple data cubes based on selection of positions in a
single image.
- Blinking between two (or more) images.
- Complete colormap editor for creation and editing of
color look-up tables.
- Overlays of vectors, markers and text from a
user generated file.
- Support for TrueColor windows.
