Desktop Art people -

  the last nightly build from Athens included desktop artwork, but the result is low-contrast. An experiment with the alternate desktop also showed problems with contrast.

  The 22.04 desktop base might be sensitive to alpha channel in the PNG file.  I removed the alpha channel locally using

   $ convert OSGeoLive/desktop-conf/osgeo-desktop.png -alpha off out.png

you can test any PNG file in the terminal with the $file command and look for  RGBA  or RGB  format. Also we can continue to change the artwork itself to find a visual solution.

   this is a blocker for the beta1 build, so feedback and solutions are welcome.

   best regards from Berkeley, Calif.   --Brian M Hamlin    / MAPLABS  /  OSGeoLive PSC
