[mapserver-users] theme on the fly with mapserver
Hi, i'm new in the list and i'm starting to use MapServer I created a web-client to see wms services, query and legend, using geotools. I would now like to create dynamic themes (theme on the fly). It's possible? how can you do with geotools? peppe ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users

[mapserver-users] Create a file GML from a layer of type annotation.
Hi, I want to create a data file, in GML, starting with a layer of type annotation generated by MapServer as WFS. I've only been able to create the file GML using LAYER- TYPE = POLYGON. This does not serve me, because it includes all the elements of the layer. I want a layer that contains only the items that MapServer decided that should be labeled. The goal is to use data from the labels in other programs. So, other GIS formats can be fine. Thanks for any advice.

Re: [mapserver-users] Create a file GML from a layer of type annotation.
Ciao José. You can get the WFS layer in a free desktop GIS, like QGis (qgis.org) via a default plugin which must be activated, and then export in shapefile. If you need GML use ogr2ogr; qgis also has a converter plugin, but I never used - be careful to GML version...

Re: [mapserver-users] Failed to show Arabic labels with MapServer 5.2
hi, yes this is the behavior that's used (with agg, but gd also): the label text is split in individual characters, and each one is rendered individually with a specific position and angle, and therefore the joining between characters is lost (this isn't specific to the outlining case, as can be seen on jackey's no_outline example). Unfortunately, there's no simple fix, and even if so this would require rewriting the entire angle follow code. This would require that the text be rendered in one pass, following a smoothed curve that fits the line geometry. AGG can sort of do this (see the trans_curve examples in your agg source dir or on the website http://antigrain.com/demo/index.html), but the characters are deformed. It's an option that I have tested locally but gave up with seeing the quality of the results. does anyone have experience with pango and know if it could solve this problem ? cheers, thomas On Tue, Nov 18, 2008 at 21:50, TC Haddad [EMAIL PROTECTED] wrote: on re-reading Steve W's point #2 - perhaps the specific bug is that there is a difference with when in the sequence of drawing, OUTLINECOLOR is applied i) when ANGLE is AUTO, OUTLINECOLOR is applied after the whole label is drawn ii) when ANGLE is FOLLOW, OUTLINECOLOR is applied after each letter is drawn so this ends up making a joined Arabic label look fractured if both OUTLINECOLOR and ANGLE FOLLOW are used at the same time.

That is, I do see the problem you are referring to, but the cause is not the font (the joined letters are as they should be). The real problem that I see is the fact that you are using OUTLINECOLOR. This is putting a 1 pixel white outline on *each* letter. This approach works in English and languages where the letters don't attach in printed form. But in Arabic, where whole worlds are joined, the outline should be applied at the level of the word, not at the level of the letter. As far as I know this feature does not exist in Mapserver at the moment, so it would have to be requested.

[mapserver-users] UTF-8 + SDE + GetfeatureInfo
Hey everyone, We're having a bit of a problem performing getfeatureinfo queries with mapserver. The french characters are coming out of the database as ISO-8859-1 instead of UTF-8. The database and servers are configured as UTF 8, the map files and the query templates too. Actually text/plain also has problems so it's not the templates. We're trying to encode everything as UTF 8 so me specificying ISO-8859-1 in the meta tag of the html query template doesn't work. GetFeatureInfo results: Layer 'SoilOrder' Feature 10894: OBJECTID = '10894' SLC_SOIL_ORDER_V31_22_ID = '81600931' SOIL_ORDER_NAME_EN = 'Chernozemic' SOIL_ORDER_NAME_FR = 'Chernoz�mique' - error is here in my browser. SOIL_ORDER_PCNT = '84' SHAPE = 'shape' Any idea if there are outstanding problems here with SDE and mapserver not playing nice with this? We're beating our heads against the wall thinking about what config we could have missed. Oh - labels with french are fine, and so are legends; it's only the getfeatureinfo queries that have troubles.

[mapserver-users] php mapscript objects in session?
Hi- I'm using ms4w 2.2.7 and I've run into a problem. Ideally I'd like to create the MapScript map object and store it in the session: $_SESSION['map'] = ms_newMapObj($getMapPath); This works fine for the that page, for the first call, but when I attempt to reference it later I get a PHP error: Fatal error: Object has an invalid _handle_ property Am I missing something here?

Re: [mapserver-users] Create a file GML from a layer of type annotation.

You can get the WFS layer in a free desktop GIS, like QGis (qgis.org) via a default plugin which must be activated, and then export in shapefile.

Re: [mapserver-users] Create a file GML from a layer of type annotation.
Hi, Maybe is useful explain more precisely my goal. The attached image is a PNG obtained by using shp2img. The layer displayed is an ANNOTATION LAYER. The labels are generalized by MapServer. I wish to get the labels displayed in this extent, in this scale, with this degree of generalization, in a GIS format, like GML, or ShapeFile. I wish to use these file in GMT, that no have implemented labeling algorithm. My attempts: 1. shp2img: i obtained PDF files, which can be integrated in the final map using something like Inkscape. 2. WMS: only can obtain a raster image. 3. WFS: I have been able to generate GML files using an WFS request,of type GetFeature. However, GetFeature work on all elements, without caring for the widespread labeling. I do not want all the labels, only those that have been generalized to a certain scale. In the past, I used MapScript. If I remember correctly, I could do this by using a script in PHP or Python. Correct? Thanks for any advice.

Re: [mapserver-users] Create a file GML from a layer of typeannotation.
Hi, I guess that annotation layers are not supported for this use and you should somehow create a point type layer that acts like the annotation layer. There needs only be two colums in the schema, geometry and name. I don't know it could be done, but have you tried just to change the layer type to point? -Jukka Rahkonen- -Alkuperäinen viesti- Lähettäjä: [EMAIL PROTECTED] puolesta: José María Michia Lähetetty: pe 21.11.2008 5:51 Vastaanottaja: Pietro Giannini Kopio: mapserver-users@lists.osgeo.org Aihe: Re: [mapserver-users] Create a file GML from a layer of typeannotation.

There needs only be two colums in the schema, geometry and name. I don't know it could be done, but have you tried just to change the layer type to point? You are right. The server WFS does not support ANNOTATION layers. I have not tried to change the type of geometry of the layer to point. However, the geometry type of data is polygon, so I can easily convert to centroids. The test that I've done it, is to change the type of geometry of the layer to the type polygon, instead of annotation. In this way, I've moved closer to the goal. But the GML file that I have been able to obtain, is the product of a REQUEST = GetFeature. Because of this, the result contains all elements, not only those items with generalized labels by MapServer. I think that some scripting can be used to read de labels cache, and write the data in a convenient way. I still have not been able to explore this alternative. -Jukka Rahkonen- Thanks Jukka! -Alkuperäinen viesti- Lähettäjä: [EMAIL PROTECTED] puolesta: José María Michia Lähetetty: pe 21.11.2008 5:51 Vastaanottaja: Pietro Giannini Kopio: mapserver-users@lists.osgeo.org Aihe: Re: [mapserver-users] Create a file GML from a layer of typeannotation.
