[mapserver-users] GEOMTRANSFORM definition causing an error

[Stephen Woodbridge]

tday,

Lets try to see if we can eliminate if the value is the problem of the 
call is the problem. Try this:

GEOMTRANSFORM (buffer([shape], 0.0)

This should call the buffer and return the same object. If this works 
then we can assume that buffer is working and the issue is setting a 
valid value.

This also might be related to using the Orcale connection. If you have 
the same data in a shapefile and could try your test with that that 
might be revealing.

More questions:
o Where are you seeing this error message?
o Do you get the same error when using shp2img from the command line?
o What does you whole mapserver CGI request look like?
