[tlocoh-info] display tif in background of animation

[Andy Lyons]

Hi Anna,

Thanks for your question. The quick answer is that displaying rasters in 
the background is not currently supported in the lxy.exp.mov() function. 
This has been on my to-do list for a while, so I'll go ahead and add it 
and issue a package update later this week.

In the interim, if you are interested in a natural earth backdrop you 
could potentially use lxy.exp.kml() to export a set of time-stamped 
locations for Google Earth, and play an animation with Google Earth's 
animation toolbar (and if desired record it using a screen capture 
program).

Cheers,

Andy
