Re: question on DisplayRendering - setSize question

Hi Curtis,
i was able to get projection control & the aspect ratio to work O.K. but
still not able to reset the default size (i've tried your example as below
but it still has no effect on the display size).  something must be
ignoring the DisplayPanelJ2D in DisplayImplJ2D - do i need to use another
default display renderer (i.e., one of the other constructors for

i'm missing something for sure.


P.S. also thanks tomw, you got me out of the stuck mode & re-started.  i
have been looking at/using the examples - both the NCEP & Test58, but
thought there might be a way to change the default size.
