SV: [mapserver-users] Clipping out unprojectable area?
Hi.
You could try something like this:
DATA "geometri from ( select geometri, * from general.country where
ST_Intersection(geometri,GeomFromText('POLYGON((12 0,18 0,18 84,12 84,12
0))',4326)) ) AS FOO USING UNIQUE ogc_fid USING SRID=4326"
It's not very nice, but it works.
Regards,
Espen

Re: [mapserver-users] 'OSGeo.MapServer' doesn't contain any public member
Meenu, I'm not sure about this problem, mapscript_csharp.dll should always expose all of the classes of the MapScript API. You can use the object browser or the .NET reflector ( http://www.red-gate.com/products/reflector/) to inspect the classes exposed by this dll.

[mapserver-users] Actual coverage data+colormap
Is it possible to include the colormap from an image being served as a coverage through mapserver? In other words, definining BYTE or INT16 for the IMAGEMODE will provide the actual data from the raster (which is what I am after), but the colormap is discarded when the data is requested through a GetCoverage request. Then I tried PC256 for the IMAGEMODE but I lost the actual data. Is there currently a way to allow me to include a colormap in the OUTPUTFORMAT definition, while providing the actual data through a GetCoverage request? I have defined the output format as follows: OUTPUTFORMAT NAME "GTIFF" MIMETYPE "image/tiff" DRIVER "GDAL/GTiff" EXTENSION "tif" IMAGEMODE "BYTE" TRANSPARENT TRUE FORMATOPTION "COMPRESS=PACKBITS" END Thanks in advance, Alex ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users

SVG is a vector format which is rendered by the browser, are you using the same browser to access both servers? I'd suggest you start by comparing the SVG output from both to try to figure the difference (it's XML-ish) between the output from your two servers, and then we can go from there.

Re: [mapserver-users] parsing error about setting debug level
Peisheng Zhao wrote: Hi all I set debug level in map file as "DEBUG 5". But I always get the error message: getSymbol(): Symbol definition error. Parsing error near (5):(line 88) What's wrong with it? Which version of MapServer are you using? To use the "DEBUG 5" syntax and other stuff in RFC-28, you need MapServer 5.0.0 or more recent. (see http://mapserver.org/development/rfc/ms-rfc-28.html) Before 5.0, you could only use DEBUG ON/OFF (or TRUE/FALSE)... so if you're using MapServer 4.x that could explain the error.

Re: [mapserver-users] Mapserver rendering with 24 bit colour
Hi, Not so that everybody gets answered, sometimes nobody just knows the answer, and after all, this is voluntary. But still, I can see from the archives that Thomas Bonfort had a try on the same day and only one and a half hours delayed :) -Jukka Rahkonen- Lähettäjä: mapserver-users-boun...@lists.osgeo.org [mailto:mapserver-users-boun...@lists.osgeo.org] Puolesta David Nugent Lähetetty: 14. toukokuuta 2009 8:01 Vastaanottaja: David Nugent Kopio: mapserver-users@lists.osgeo.org Aihe: Re: [mapserver-users] Mapserver rendering with 24 bit colour On 06/05/2009, at 1:52 PM, David Nugent wrote: Once I completed upgrading to mapserver 5.4, I decided I'd give the new AGG renderer a try. ~ However, as a by-product of changing renderer, the metatiles produced by mapserver differ slightly in colour. Some agree exactly to the RBG colours I am providing, others are rendered with slight variations, and when viewed on the web it becomes fairly obvious where the meta tile borders are. This is to follow up on my own question to which I received no response either on the list or otherwise in case anyone else runs into the same or a similar problem. I finally found the problem in that the php mapscript had a bug, and that "AGG_Q" (AGG with quantize enabled) was being selected regardless that I was trying to tell it to do it differently. Once I correctly set it to AGG without quantize, the colour variation between tiles disappeared and all is well. One interesting aspect of this is that the average file size did not increase significantly when dropping quantize although in general the tiles rendered using AGG are around 40-50% larger than PNG8.
