Re: [mapserver-users] passing variables to includes

[pe_lord]

To solve this problem, i've used an scaletoken with multiple parameters
(sorted). 

SCALETOKEN
NAME "%f%"
VALUES
"0" "2|1"
"100" "2|1"  
END
END

And inside my query string to postgis, I've substitued these sorted value
into a sub select and I split with the '|'. 

DATA "the_geom from (SELECT table.*, d.* FROM table, 
(select split_part('%f%','|',1)::integer as
p1,split_part('%f%','|',2)::integer as p2)as d ) as subquery using unique
cod_instl srid=3857"

Re: [mapserver-users] Rewrite rule problem

[gorank]

Hi Andreas,

As you sugested I have added in* httpd.conf* file following

 
  SetEnvIfExpr "%{QUERY_STRING} =~ /^(.*&)?map=([[:alnum:]]+.map)(&.*)?$/"
MS_MAPFILE=C:/ms4w/apps/Demo/$2 
 

 RewriteRule /cgi-bin/Demo/wms /cgi-bin/Demo/wms?MAP=MS_MAPFILE [PT,QSA]

and when I put URL
http://localhost:81/cgi-bin/Demo/wms?map=N1.map=GetCapabilities=WMS=1.3.0

I receive the following message:
msLoadMap(): Unable to access file. (N1.map)

As addition in the C:/ms4w/httpd.d folder I have file httpd_Demo.conf file
with following content

Alias /Demo/ "/ms4w/apps/Demo/"

  AllowOverride None
  Options Indexes FollowSymLinks Multiviews
  Order allow,deny
  Allow from all


What I'm doing wrong.

Best regards,
Goran

[mapserver-users] How to control the mime-type of MapCache-WMS outputformats

[Rahkonen Jukka (MML)]

Hi,

We found on issue when updating MapCache to version 1.6 from some ancient 
version.
We have png-format configured to 8-bit by limiting the number of colors like


  fast
  256


Now the WMS service is advertising this format with mime type "image/png; 
mode=8bit". However, we have existing applications which make GetMaps with 
plain "=image/png"  and that used to work with the old MapCache version.

Is there a way to override the mime type with the MapCache config file? I can 
see a promising  section in the RFC 119 
http://mapserver.gis.umn.edu/development/rfc/ms-rfc-119.html


  mvt
  application/vnd.mapbox-vector-tile


However, it is not clear from the documentation if mime_type configuration is 
supposed to work also for the image formats, and in which MapCache version.

Re: [mapserver-users] Rewrite rule problem

[Eichner, Andreas - SID]

Hi,

I guess you should use SetEnvIfExpr to test the query string for 
the MAP parameter and set the environment variable using the value.
Wrap it into a  block to do this only for a specific URI:


  SetEnvIfExpr "%{QUERY_STRING} =~ /^(.*&)?map=([[:alnum:]]+.map)(&.*)?$/" 
MS_MAPFILE=C:/ms4w/apps/Demo/$2


IHMO this won't work though as MapServer's msCGILoadMap() function prefers the 
MAP param and uses the MS_MAPFILE environment variable only as a fallback.
As MS first checks if the MAP parameter points to the name of an environment 
variable containing the map file and scans the query parameters from left to 
right you can prepend a fake MAP parameter pointing to MS_MAPFILE.
For example a request to
  /cgi-bin/Demo/wms?map=N1.map=GetCapabilities
Needs to be written as
  /cgi-bin/Demo/wms?map=MS_MAPFILE=N1.map=GetCapabilities
You can do this using a RewriteRule like
  RewriteRule /cgi-bin/Demo/wms /cgi-bin/Demo/wms?MAP=MS_MAPFILE [PT,QSA]
