Important Changes for Release 1.8
SAOtng is an evolving (some would say oscillating) system: we try
to respond to user needs as quickly as possible. The following changes
have been initiated by user feedback:
- Display of FITS image extensions and binary tables
- SAOtng now can display FITS image extensions, FITS binary tables
and raw event files. See Loading an Image
for more information. (NB: If you maintain a PFILES directory, please
delete any old fitsextract.par file found there, since this version
of the fitsextract program has new parameters.)
- SAOtng now can apply filters to binary tables and event files.
- See Event Filtering for
more information.
- Display of compressed FITS and WWW FITS files
- SAOtng now can display compressed FITS files by automatically
decompressing them on the fly. It also can retrieve files over the
Web. See Loading an Image for more
information.
- Support for IMAGE_PATH environment variable
- SAOtng now will search for image files in directories specified
by the IMAGE_PATH environment variable.
See Loading an Image for more information.
- Fixing marker parameters
- SAOtng now allows you to "fix" a variety of parameters for
specified markers so that they cannot be moved, resized, etc.
See Fixing and Freeing Region Markers
for more information.
- Enhanced scaling support
- SAOtng now can support a different scale algorithm for each
display frame. Also the Scale menu option allows you to choose different
ways of setting the scaling min and max values for a given frame.
See The Scale Menu
for more information.
- Changes to tiling
- In tiling mode, previous versions of SAOtng automatically changed frames
as the mouse moved between frames. This feature annoyed users, so we
disabled it. Frames now are changed by means of the Frame menu, even
in tiling mode. The auto-switching of tiled frames can be turned back
on by means of a button on the Control Panel.
- Changes to the zoom xpa access point
- We have split the zoom public access point, which previously
controlled zoom, pan, flip, and autoflip into 4 separate public
access points called "zoom", "pan", "flip", and "autoflip".
See the SAOtng XPA List for more
information.
- Changes to auto blocking
- When blocking is set to auto in the Images
menu, we now restrict the valid block factors to be powers of 2. This
change was necessary in order to ensure accuracy in the placement of
region markers. To remove this restriction, set the environment variable
SAOTNG_RESTRICT to "false".
- Marker keystrokes (obscure)
- Because of conflicts with IRAF, the i,e,s,b keystrokes within a
marker (used to change a marker to "include", "exclude", "source", or
"background", respectively) have been changed to ctrl-i, ctrl-e, ctrl-s,
and ctrl-b.
- IRAF-related changes
- SAOtng now sets up the IRAF socket and unix pipe
parameters to match the IRAF defaults. The fifo parameters still are
set to "none", however.
A slight modification has been made to the command line for extracting
FITS images from IRAF images. We hope this change will alleviate the
(passive) "Write to IPC with no reader" error messages that sometimes were
printed out as an IRAF image was being processed.
- Internal changes
- Our FITS support (e.g. fitsextract) was based on an old saord/FITS
library that only understood primary FITS images. It has been
replaced with the newer saord/fitsy library that also handles FITS
image extensions and binary tables. If you were using the old FITS
library, please contact us for information about how to convert to the
new and much nicer library.
- Netscape 4.0.x problems
- Please note that versions 4.0.3 and 4.0.4 of Netscape ignore
the -ncols switch that limits the number of colors hogged by
the program. Therefore, when you are running Netscape 4.0.x, SAOtng
will not be able to allocate colors from the public colormap and will
be forced to switch to a private colormap. There is no work-around for
this anti-social behavior on the part of Netscape. (Note that
Netscape 3.x works properly.)
