[Mapserver-users] Querystring parameters for selecting OUTPUTFORMAT

[Ed McNierney]

Folks -

I'm trying to use the new OUTPUTFORMAT support in 3.7 and I'm getting lost.

Specifically, I'm trying to define several named OUTPUTFORMATs in the MAP file and select one through a querystring parameter.  First, if there's already a way to do this, let me know because I couldn't find it.

I can define multiple OUTPUTFORMATs but I only get either the first one or the one specified in the IMAGETYPE statement.  I added code to mapserv.c in the "obvious place" where the CGI form variables are parsed; this looks for an IMAGETYPE variable and sets msObj->Map->imagetype to that string value.  However, it appears that in the earlier processing of the MAP file, the outputformats are enumerated and the default selected.  My setting of msObj->Map->imagetype has no effect because it seems the decisions' already been made.

There's a lot of new code here and I'm wandering through it but haven't found the answer yet.  Any pointers would be appreciated - thanks!
