Notes on photo sphere/panoramic EXIF metadata
- Google's EXIF/XMP metadata tag specification for panoramic images
- Panorama images with sky are to have a negative value for the CroppedAreaTopPixels tag. (The panoramic viewer of Facebook ignores the value altogether, though, and assumes the horizon in the middle of the picture.)
- If a camera or software normally produces panoramic images with cylindrical projection, then doing a vertical capture actually produces a transverse cylindrical image. There is no standardized value for the EXIF ProjectionType field to cover this. (One option is to reproject them to equirectangular — which, again, is not very well supported.)
- Facebook's document on what tags to set
- The Facebook web interface insists that FullPanoHeightPixels be half the size of FullPanoWidthPixels. Else you get “no new photos were uploaded”.

LXDE not ready for multi-monitor setups
I have been using Xfce since about August 2010 (before that: icewm). I always kept on hearing the occassional occurrence of LXDE when topics of light window managers were raised, so I today I gave LXDE a spin, for completeness. In my home environment, I attach an external monitor to yield some extra space, but, as it seems, lxpanel-0.5.8 does not support placing the panel on a specific monitor (rather than the X screen), so LXDE just became irrelevant to me. FYI, the screen/display config is:
Screen 0: minimum 320 x 200, current 1280 x 1332, maximum 4096 x 4096
LVDS1 connected 1024x600+0+732 (normal left inverted right x axis y axis) 220mm x 129mm
1024x600 60.0*+
800x600 60.3 56.2
640x480 59.9
VGA1 connected 1280x1024+0+0 (normal left inverted right x axis y axis) 376mm x 301mm
1280x1024 60.0*+ 75.0 72.0
1152x864 75.0
1024x768 75.1 70.1 60.0
832x624 74.6
800x600 72.2 75.0 60.3
640x480 72.8 75.0 66.7 60.0
720x400 70.1
640x350 70.1
