I submitted the 'stride' request to the IDL comment form at


Anyone care to second it?

I also submitted a request to have MAP_IMAGE handle 24-bit images (instead
of having to call it 3 times, once for each image plane).

I also agree with the sentiment expressed by Struan Gray in another thread:

RSI has greatly expanded IDL in many directions (ENVI, RiverTools, etc.),
but it is still difficult to get a correct rectangular border around a
simple cylindrical-equidistant global map.  Every one I draw has strange

Another thing that drives me nuts is differences between the Hershey and
Postscript font character ordering.  Everytime I want to convert a plot
from X to PS, I have to insert special code to handle any special

Another of my pet peeves - no real 24-bit support for the Postscript device.

All that said, many things have been improved in the internals over the
years.  I love /NAN in TOTAL, etc.  I would like to see continued efforts
by RSI to make every detail in IDL right.  Keep reporting those bugs (I
mean features)!
