Umm ... but $FG_ROOT/Aircraft/bo105/splash.rgb *is* "aggressively"
compressed. Does it crash fgfs for anyone? I also tried other such
textures -- no crashes.
Can someone send me a link to a splash texture that crashes fgfs
for him/her? And a backtrace for the crash if possible.
BTW: KDE users can easily check if a texture was "aggressively"
compressed. I use this bash shell function:
sgi() {
for i in $*; do
echo $i
kfile --av "$i" 2>/dev/null|
egrep "(Comment|Technical Details)"|
sed -e 's/Comment: *//' -e 's/Technical
Details: *//';
echo
done
}
Used on the bo105 texture:
$ sgi $FG_ROOT/Aircraft/bo105/splash.rgb
/usr/local/share/FlightGear/Aircraft/bo105/splash.rgb
Name: Bo105 -- http://www.flightgear.org/ -- Melchior
FRANZ 2005
Bit Depth: 24 bpp
Color Mode: RGB
Compression: Runlength Encoded, 50.5%
Dimensions: 512 x 512 pixels
Shared Rows: 0.3%
The "Shared Rows" percentage says that it's "aggressively" compressed.
It's a silly term, actually, as this is by no means aggressive. The
compression described in the SGI Image spec *is* "aggressive", and
there is no other compression mentioned at all. Loaders which don't
grok it are just broken.
