So essentially, the patch should be modified to remove the ROLLBACKs
from msPOSTGISLayerGetShape() in a safe way.
Just to make sure I'm properly interpreting the status of what's getting to
be a bit of a long thread here...
You're saying that this patch:
http://trac.osgeo.org/mapserver/attachment/ticket/2497/ms_postgis_begin_to_
connect.diff from this bug:
http://trac.osgeo.org/mapserver/ticket/2497
is not entirely correct and should be modified?
I have applied this patch and it is not properly working when using
{map,layer}Obj_queryBy{Point,Rect,etc.} functions. This was confirmed by Dave
Fuhry.
But this change has not happened yet, I gather?
I don't know about any other patch.
I assume that if/when there's a new patch, notice will be posted either in
this mailing list thread or that bug?
Yes. I am looking for the notice here in the mailinglist and to the bug
thread.
I ask b/c I build mapserver from source and am currently using that patch,
and I want to make sure I recompile if that patch changes.
I want to recompile mapserver with the patch which is correctly working with
{map,layer}Obj_queryBy{Point,Rect,etc.} functions.
So, I think the status of this problem is waiting for the new patch.
Ivan
Thanks.

Re: [mapserver-users] AGG vs. GD: Label placement problems
Yes, that's exactly the problem, as there's a difference of a few pixels between the size of the label calculated by gd and the size it actually takes when rendered with agg. I realize now that it can cause some quite visible problems in the case you show here (labels to the left), as in that case the few pixels difference can cause the label to overlap the point symbol.

Hi Carla, Please remember to use reply to all in order to send your message for the mailing list as well. I hope I understand this correctly. So your original data (the shapefile) is in epsg:23030? Then you should have in mapfile, in corresponding LAYER section PROJECTION init=epsg:23030 END Next, because you are willing to deliver that layer through WMS in epsg:4230, it is good to add this to layer METADATA as wms_srsEPSG:4230 By looking at my old mapfiles wms_srs metadata seems not to be compulsory if WMS service will only be used in one output projection which is the same as the main MAP projection. Anyway I believe it would be good habbit to have it. Third, you should give the default output projection in MAP section as PROJECTION init=epsg:4230 END And last calculate the bounding box containing your data in the mapfile projection (epsg:4230) and feel in the values as EXTENT of the map object. I try to read your messages once again faithfully and I feel you are giving a bit conflicting information. In one place you say you are willing to publish your data in ETRS89, wich I believe to mean epsg:4258. If this is the case then insert that value to wms_srs and mapfile projection instead of 4230. Why do you play at all with epsg:4230 if your data are not using it, and you don't want to any output in that projection either?

Re: [MAPSERVER-USERS] cs2cs problems
Hi, I feel we are getting closer to common understandment. First, for my mind you exactly _do_ want to reproject your data, even if just on-the-fly from epsg:23030 to epsg:4326. I do not know what projection you need to use with Google Earth but let's hope that epsg:4326 is correct. Mapserver is doing re-projection for you if you first tell it in LAYER the original projection of the data, and in the MAP level the output projection. Now I suppose your LAYER is ok if you have set the projection to +init=epsg:23030. I have never heard about using cs2cs for setting Mapserver projection but it does not prove that it is not possible. The methods I have used are using epsg code likeinit=epsg:4230 or proj4-strings. The usage of the projection strings is explained here: http://mapserver.gis.umn.edu/docs/reference/mapfile/projection Another document to look through is: http://mapserver.gis.umn.edu/docs/howto/wms_server I have to say that it was not very easy to find a document describing promptly how to use Proj4 strings in mapfile, even that possibility is often mentioned in discussions. -Jukka- Lähettäjä: CARLA FERNANDEZ [mailto:[EMAIL PROTECTED] Lähetetty: 18. maaliskuuta 2008 14:15 Vastaanottaja: Rahkonen Jukka Kopio: mapserver-users@lists.osgeo.org Aihe: Re: [MAPSERVER-USERS] cs2cs problems Hi Jukka, Thanks very much for your interest!! and sorry for the conflicting information...
