Release history for xearth, version 1.0
Kirk Lauritz Johnson <tuna@cag.lcs.mit.edu>
29 September 1995
xearth version 1.0 (29 September 1995)
Many new features:
- new position specifier (random)
- Mercator projections (-proj)
- rotated views (-rot)
- shading discontinuity at terminator (-term)
- rendering X image only once (-once)
- user-specifiable marker information (-markerfile)
- user-specifiable marker alignment (align=xxx)
- user-specifiable label position (-labelpos)
- mix of single- and double-pixel stars (-bigstars)
- support for new display depths (12, 15, 16, and 24 bits)
- inclusion of Robert Berger's gamma test image
Plenty of general code tuning and cleaning.
New copyright notice to reflect Unisys Corporation's patent on the
LZW compression technique employed in the GIF file format.
xearth version 0.92 (1 June 1994)
Fixed the broken code that was attempting to handle the situation
when the requested font couldn't be loaded.
Added black border/outline to label text (as was already being done
for marker text).
Several small changes to keep lint happier.
xearth version 0.91 (25 May 1994)
Added code #ifdef-ed by NO_RANDOM and NO_SETPRIORITY to provide a
standard workaround for systems without random() and/or
setpriority().
First cut at support for monochrome mode and 1-bit framebuffers.
Monochrome mode is the default on 1-bit framebuffers; it can also be
enabled with the "-mono" command line flag or the ".mono" X
resource.
Provided built-in bzero() workalike to avoid problems with pre-X11R5
systems not having <X11/Xfuncs.h> and dealing with the ugly
machinations required to automatically determine the right thing to
do.
Fixed bug in man page; the description of the interpretation of
positive and negative values of longitude was incorrect.
Fixed and uncommented the code that tries to kill the resources of
any previous clients that had scribbled on the root window and left
an _XSETROOT_ID property. (Note that xearth still doesn't set an
_XSETROOT_ID property itself; see the big comment near line 380 of
x11.c for details.)
Minor performance tweaks and a few bug fixes in the dithering code.
Added complete text of copyright to all source and documentation
files (necessary for inclusion in the X11R6 contrib package).
xearth version 0.9 (14 May 1994)
Wholesale changes. Many new features, including:
- child process no longer forked by default
- support for fixed, sun-relative, and orbital viewing positions
- lines of longitude and latitude
- (random) star-filled backgrounds
- support for both command line options and X resources
- brightly-colored location markers
plus numerous other small changes and bug fixes.
xearth version 0.5 (23 July 1993)
Initial release
