[Chameleon] Error Rendering Map Image

Fri Aug 19 00:57:58 EDT 2005

Hi Jay,

Firstly, thanks for replying!
Secondly...

- What version of MapServer and Chameleon did you upgrade from?
ms4w 1.0.3 and chameleon 2.0 to ms4w 1.2.1 and chameleon 2.2

- Do your two working applications use a different output format from
those that have stopped working?
They do not contain an explicit output format. (But neither did the 
non-working apps.)

- Can you post the first 20-25 lines of your MapFile?
Please see below. 

I think we have actually resolved the problem, but I am really not sure how. 
We did some copying and pasting from other map files and that seemed to do 
it, but I get the feeling that not all of the new code was necessary to fix 
the problem. The two versions of the new/old portions code are pasted below. 
While it is no longer critical, my colleagues and I could really benefit 
from an explanation of why the new code works, while the other code doesn't. 
Perhaps this is more of a MapServer list question, after all, but I thought 
I would continue the thread here since it was started in this list.

I really appreciate your help!

Thanks,
