Version 7.0
-

-
-

3-D Data Visualization
-

-

Previous versions of DS9 would allow users to load 3-D data - into traditional 2-D frames, and would allow users to step - through successive z-dimension pixel slices of the data cube. - To visualize 3-D data in DS9 v. 7.0, a new module, encompassed - by the new Frame 3D option, allows users to load and - view data cubes in multiple dimensions.

-

The new module implements a simple ray-trace algorithm. For - each pixel on the screen, a ray is projected back into the - view volume, based on the current viewing parameters, - returning a data value if the ray intersects the FITS data - cube. To determine the value returned, there are 2 methods - available, Maximum Intensity Projection (MIP) and Average - Intensity Projection (AIP). MIP returns the maximum value - encountered, AIP returns an average of all values encountered. - At this point, normal DS9 operations are applied, such as - scaling, clipping and applying a color map.
-

-

Rendering time is independent of the actual data cube size. - Instead, the time it takes to render is based on how many rays - are needed to project the data cube upon the screen in the - view volume and the current zoom factor. The new module - requires no special hardware or graphical processor unit (GPU) - and the rendering time is adequate for interactive GUI - manipulation on most computers. The rendering engine is - developed using the POSIX thread library, allowing multiple - light weight processes to be spawned to complete an image in - parallel. The number of threads actually generated is a user - specified parameter. Since all modern hardware contain - multiple CPU cores, the default value is 8 threads. For larger - work stations, this number can be increase. For every doubling - in the number of CPU cores available, rendering times decrease - approximately 75%.
-

-

The new module is support on all hardware platforms currently - supported by DS9, including 32-bit and 64-bit versions of - Linux and MacOSX, and 32-bit versions of Windows and Solaris.
-

-

All 2-D graphics, regions, cross hairs, contours, and - coordinate grids, are applied to the current slice, which is - selected by the user. When the user wishes to match or lock a - 2-D image and to a 3-D data cube, the current slice is used to - determine the rendering solution. The user can crop the data - cube for all 3 axes via the command line or the GUI. The new - module also supports FITS event files binned into a data cube.
-

-

All printing support has been extended to the new 3-D module. - The user may generate 3-D images in Postscript, JPEG, TIFF, - and other formats, just as in the 2-D case. Furthermore, - native printing is supported for the Windows version.
-

-

DS9 analysis macros have been enhanced to fully support the - new 3-D module, allowing the user to invoke external analysis - tasks based on the current view parameters and to return - results back into DS9 in the form of text, plot, 2-D image, or - 3-D image.
-

-

Funding for 3-D data visualization was provided by the JWST - Mission office at Space Telescope Science Institute - (NAS-03127)

-

Color Tags
-

- The purpose of color tags are to highlight (or hide) certain - values of data, regardless of the color map selected. The user - creates, edits, and deletes color tags via the GUI. To create a - color tag, enter the Colorbar Mode, and click once on the - colorbar. This creates a default color tag. Click and drag to - change the values. Click and drag on one side to increase or - decrease the value. Double click to manually edit the values and - color. Place the cursor over the color tag and press the delete - key to delete it. From the color parameters dialog, the user can - load, save, and delete all color tags for that frame.
-

Regions
-

- Regions now support analysis tasks unique to each region type. - In the menu of the region dialog, the Analysis menu - will contain any type specific analysis tasks. The Circle, - Ellipse, Box, Polygon, and Point - regions now support interactive 1-D cuts along the 3rd axis of - 3-D data cubes. The Line, Vector, and Projection - regions support 2-D cuts through the current slice of 2-D and - 3-D data. The Auto Plot option under the regions - preferences can be used to specify if a plot is automatically - generated when the region is created.
-

Analysis
-

- DS9 analysis macros have been enhanced to fully support the new - 3-D module, allowing the user to invoke external analysis tasks - on the current slice of 3-D data cube. The macro $z is - now supported for 3-D data. In support of Funtools, - the PLANE keyword is supported.
-

Slice
-

- DS9 now allows the user to load a 3-D data cube one slice at a - time via the GUI or from the command line. Use the option -slice - - - - - - - - to specify that all following 2-D files are to be - interpreted as a slice of a 3-D data cube.
-

Photo
-

- DS9 can now load images in TIFF, JPEG, and PNG file format - directly. When loaded into a Frame, the average of the - luminosity is used. When loaded into a Frame RGB, each - channel is loaded directly. Use the -photo command - line option to specify that all following files are to be - interpreted as a photo image.
-

Export
-

- DS9 will export the current image in TIFF, JPEG, or PNG file - format with the current colorbar parameters applied. The entire - image is exported (not just the visible portion) at the native - resolution.
-

Lock/Match
-

- The support for the Lock/Match functionality of DS9 has been - greatly enhanced. The user may choose to lock/match frames, the - cross hair, cropping, the current slice, binning parameters, - scale parameters, or color map parameters.
-

Crop
-

- DS9 now supports cropping the current image, via the GUI, - command line, or XPA/SAMP in both 2-D and 3-D. The user may - specify a rectangular region of the image data as a center and - width/height in any coordinate system via the Crop Dialog, or - can interactively select the region of the image to display by - clicking and dragging while in Crop Mode. For 3-D frames, the shift-click - to change the front clip plane, and control-click to - change the back clip plane. From the command line, cropping - parameters can be specified in IRAF format.
-

ASINH Scale
-

- A new scale function has been added, ashinh, based on - the arc sinh function. This new function has similar properties - as the log function, with a=10.
-

All new GUI
-

-

DS9 now supports basic GUI elements (buttons, menus, etc) via - the native window manager API. Each port of DS9 will have a - native look and feel of each hardware platform. DS9 will take - advantage of the current user selected Theme if - supported by the native windowing system.
-

-

Postscript
-

- DS9 now generates identical postscript code for a particular - image, regardless of which hardware platform was used to - generate the image.
-

Catalogs
-

- The user may now specify coordinates in any equatorial system - (not just FK5) for a catalog search and receive results in any - equatorial system, to be plotted or saved. Local catalogs in any - equatorial system are now supported.
-

New WCS support
-

-

New WCS support for non-FITS WCS projections have been added - to DS9: TNX, ZPX, SCAMP, SIP and HEALPIX.  The keyword - WCSDEP is now supported.
-

-

Enhancements and improvements have been made in the support - for the following FITS WCS projections: COD, COO, COE, COP, - ZEA, and CAR.
-

-

DS9 now supports non-equatorial long/lat coordinate systems - in the form of xLON/xLAT and xyLN/xyLT. This includes solar - WCS HPLN/HPLT, HGLN/HGLT, and HRLN/HRLT systems.
-

-

DS9 now fully supports multiple alternative celestial WCS, if - specified. All cut/paste/copy operations, catalog, image - server, contour, regions, and coordinate grids will now use - the default WCS as selected by the user, via the WCS menu - item.
-

-

HEALPIX
-

-

DS9 now supports native HEALPIX maps, in both FITS binary - table and ascii table form. Any table with keyword - PIXTYPE=HEALPIX or NSIDE=x will be processed as an HEALPIX - image. The user may specify HEALPIX parameters within the file - specification to indicate RING (default) or NESTED order, - Coordinate System (default is Unknown),  Quadrant - (default is first), and Equator (default), North, or South - layout. The appropriate WCS is generated for the image.
-

-

External Analysis Files
-

- DS9 will now look for external analysis files in the following - locations at start up: the current directory, $HOME/bin, - /usr/local/bin, /opt/local/bin, and /soft/saord/bin - in the form of *.ds9. If found, they will be - automatically loaded. Users may disable this feature via the - presences analysis panel. DS9 will continue to load ds9.ans - and ds9.analysis if found, and users specified - analysis files as before. DS9 will verify that the same analysis - file is not loaded twice to avoid duplication of analysis menus. -
