[mapserver-users] Re: How to set SCALEBAR size and intervals in MapServer CGI >5.0?

[John Maurer]

Dear MapServer Users,
Please disregard this inquiry. I since found the problem in my CGI file. 
I was using MapServer 5.2.0 in one place but accidentally still calling 
MapServer 4.99 in another, thus causing the discrepancy in how I needed 
to reference parameters in my map file. Still, though, I wonder why 
MapServer >5.0 didn't retain the ability to reference parameters in a 
hierarchy like "map_scalebar_size" since now I have to go back and 
change all of these references in my code to "map_scalebar=size+value"?? 
Unfortunately, this change makes things so they are not backwards 
compatible.
Cheers,
John
