Hez,

I probably should dig into wavelab's source to look for clues on how, if at 
all, they take advantage of the longer scales (the ones with few coefficients). 
 The detail of the shortest scale present in the DWT uses roughly half of the 
memory of the transform.  Blowing it up into a rectangular matrix would take 
considerably more storage than the transform.  The good news is that in modern 
hardware, it's probably reasonable to ask for that amount of memory.  Of 
course, sparse storage would start to hurt on the shorter scales.

gnuplot has a map view that enters into making colored images.  At least in 
some situations, one draws a 3D plot and tells gnuplot to project it without 
perspective.  Is there anything like that to worry about in PLplot?   If you 
don't know what I mean, that is probably a good sign :)

Thanks!

Bill

Bill,

I haven't used PLplot for this, but the plimage and plimagefr
functions may be useful to build such functionality.
