[Mediawiki-l] Thumbnailer error on large file

[Dan Nessett]

We are getting a thumbnailer error on a png file of 16 Mpx. This error 
is: "Error creating thumbnail: Invalid thumbnail parameters". It appears 
there is an upper bound limitation somewhere, since Wikipedia has a 
similar problem (e.g., see http://en.wikipedia.org/wiki/
Category:Old_Ordnance_Survey_map_images).

Is this a hard limit due to limitations of Imagemagick or is there a 
global that controls the upper bound on image size that the thumbnailer 
can handle?
