I want to set a projection area larger than data's geographical coverage.
But data must still be georeferenced correctly inside map region
and coastlines in projection area should still be visible outside data area.
right now, the data is always stretched inside whole projection area.
trying to mimic with characters:
--right now--

Code below certainly does not work and stretch data to full projection
region:

*code skipped*
m = Basemap(projection='merc',llcrnrlat=37,urcrnrlat=42,\
llcrnrlon=24,urcrnrlon=34,resolution='i')
m.imshow(data, cmap=plt.cm.jet, interpolation='nearest')
plt.show()
*code skipped*
---------------------------
i fiddled with imshow's extent and clip_box keywords but since could not
get it work. and googling for a serious amount of time didnt help either.
Some posts on web mentioned bbox or set_autoscale_on related things but i
cant seem to get it. Any ideas ?
thanks.
