[mapserver-users] Re: How to set Labels dynamically
Hi Helen,
this sample-script should work:
---schnipp--
?php
//1. Map-Object and Image
$blank_map_object = ms_newMapObj('your path to the sample mapfile below');
$blank_map_object-preparequery();
$blank_map_image = $blank_map_object-prepareImage();
//2. LAYER
$draw_layer = ms_newLayerObj($blank_map_object);
$draw_layer-set('type', MS_LAYER_POINT);
$draw_layer-set('status', MS_ON);
//3. CLASS, STYLE and LABEL
$new_class = ms_newClassObj($draw_layer);
$new_style = ms_newStyleObj($new_class);
$label_obj = $new_class-label;
$label_obj-set('size', 25);
$label_obj-set('type', MS_TRUETYPE);
//Path to arial.ttf must be defined in test_fontset.txt
$label_obj-set('font', 'arial');
$label_obj-set('angle', 30);
//0x007E is the ~ sign
$label_obj-set('wrap', 0x007E);
$label_obj-color-setRGB(0,255,0);
$label_obj-backgroundcolor-setRGB(0,0,255);
$label_obj-backgroundshadowcolor-setRGB(200,200,200);
$label_obj-set('backgroundshadowsizex', 15);
$label_obj-set('backgroundshadowsizey', 15);
//...and so on
//4. Shape with label
$draw_shape = ms_shapeObjFromWkt('POINT(2502500 5602500)');
$draw_shape-set('text', ' ~ Hello World!~ Mapserver is cool... ~');
$draw_layer-addFeature($draw_shape);
$draw_layer-draw($blank_map_image);
//5. Shape to Image
$blank_map_object-drawLabelCache($blank_map_image);
$blank_map_object-labelcache-free();

Hi,
My $daLayer is defined dynamically. How should I define Label-Section in
this case?
$daLayer-set(type, MS_LAYER_POINT);
$daLayer-set(status, MS_ON);
$class = ms_newClassObj($daLayer);
$style = ms_newStyleObj($class);
$style-color-setRGB(255,0,0);
$style-set(symbolname, circle);
$style-set(size, 10);
Thank you,

Oops, you're right, drawLabelCache is a method of the map-object, but
all the same it works for me!
Perhaps a missing LABEL-Section in the mapfile-definition of your
$daLayer?

Hi Ludwig,
Layer object doesn't have DrawLabelCache method. I've tried this line
and
got an error. I'm using Mapserver installed with fgs 5.4.2.
I've tried
$map- drawLabelCache($image);
But it doesn't make any difference.

Hi,
I think there's only one line missing after $daLayer-draw($image):
$daLayer-drawLabelCache($image);

Hello,
I couldn't find documentation how to set the text labels dynamically
using
MapScript.
My application should show points with labels on the map. Points and
labels
are obtained dynamically from the database or some text file.
I add the points to the layer and draw layer as following:
$my_point = ms_newpointObj();
$my_point-setXY(-75.895, 45.9227);
$my_point-project($projInObj,$projOutObj);
$line = ms_newLineObj();
$line-add($my_point);
$shape = ms_newShapeObj(MS_SHAPE_POINT);
$shape-add($line);
$shape-set(text, 'new point');
$daLayer-addFeature($shape);
$image=$map-draw();
$daLayer-draw($image);
$image_url=$image-saveWebImage();
Points are displayed on the map, but no text. What am I doing wrong?
I will appreciate any help,
Helen

[mapserver-users] Anyone know how to set up Mapserver under IIS 7 x64?

Re: [mapserver-users] Anyone know how to set up Mapserver under IIS 7 x64?
Daniel, The x64 binaries at http://vbkto.dyndns.org/sdk/ would be near to this requirement, if we'd compile mapserver with php support. This would require at first to compile the php lib for x64 on Windows. Then you might try to use the x64 SDK package and edit the Makefile and recompile mapserver accordingly.

[mapserver-users] How to avoid warning messages for WFS and optional metadata
Hi all when defining a WFS with MapServer the GetCapabilities request returns several warnings of the type: WARNING: Optional metadata ... was missing for ... if the version is set to 1.1.0 (it does not appear for requested version 1.0.0). I do not really understand why missing *optional* metadata parameters create a warning output. Therefore my question is if there is a configuration setting that allows suppressing warnings for missing optional elements. Thanks for any hints Armin PS: When I remember well this behaviour is the same for WCS in version 1.1.0 ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users
[mapserver-users] html and ajax query
I am trying to get the user to choose from 2 comboboxes...cant seem to get this
to work...maybe someone out there can see something I am doin wrong?
I think this how it works? Using the code below
The user selects two values in combo boxes (PriceFactor and PriceArea)
Click the button to call function ReturnQueryResults
The Array is built from the values of the two dropdown boxes (id =
PriceFactor and id = PriceArea) using their ID values
The javascript call is made that calls Ajax page which sends the php page the
array of values. I then have to parse the ID (the array) with Get in the php
page, formatting the output, which is then shown on the target specified in the
Ajax page.
The results go back to the back to the ajax page
I don't have a great understanding of this...trying with a couple dropdowns to
start.
Any help would be greatly appreciated...I think I am pretty close but can use
another set of eyes...
THanks

[mapserver-users] Layer based on a view renders faster than if based on a table
Hi, I have a layer that renders faster when DATA is defined on a view than on a table with a clustered index. Here is the layer definition CONNECTIONTYPE postgis CONNECTION host= dbname=xx user=xx password=xx port=5432 DATA geom900913 FROM prevalence using unique id using srid=900913 PROCESSING CLOSE_CONNECTION=DEFER PROJECTION init=epsg:900913 END My MAP projection is also 900913 If prevalence is a Postgis View: 0.469s (2.6 seconds in OpenLayers) Postgis table: 0.781s (3.6 seconds in OpenLayers) Postgis table+index+cluster: 0.782s ( 3.4 seconds in OpenLayers) I thought that a layer definition based on a table would be much faster than on a view. What should be the expected behavior please? Please tell me is this should be asked to postgis forum. thanks Steve ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users

Please tell me is this should be asked to postgis forum. I'd suggest you capture the exact SQL query that is run in each case (using DEBUG/MS_ERRORFILE) and check that the difference in time indeed comes form the PostGIS queries. If that's the case then you could submit a question to the postgis list based on that, taking MapServer out of the equation. If on the other hand the queries take about the same time and the time difference is in MapServer's code (which I doubt) then we'd need more details (ideally a testcase) to be able to reproduce and troubleshoot the issue.

Help Conservation group win $40,000 for scholarship Program! Please send on this note to your network to extend the SCGIS family and increase our chances of winning! RED BALLOON SEARCH Tomorrow! Help Conservation group win $40,000 for scholarship Program! Importance: High http://www.edc.uri.edu/scgis/ SCGIS Takes On The DARPA Challenge: Help the Society for Conservation GIS win $40,000 for our international scholarship program and improve our SCGIS networking efforts! www.scgis.org The Challenge: Help the SCGIS Team locate 10 RED Weather Balloons THIS Saturday Dec 05, 2009. This is a one day event and all we need are your eyes...We do NOT need individuals to drive all over the countryside, we need increased numbers of observers. If you forward this email to ALL individuals on your contact list we have a greater chance of winning. The only way we can possible win this challenge is to have thousands of eyes looking for these red weather balloons located throughout the United States. You do NOT have to be a geocacher or own a GPS to participate, we just need you to keep an eye out for the balloons. This money will be used to help conservationists world-wide to gain the skills they need to conserve the environment, indigenous tribes, and local communities. Why SCGIS: Because the Society of Conservation GIS is comprised of the world's smartest mapping geeks, nerds, wonks, and pros, if we can't come up with 10 geographic locations for bright red balloons, who can? Oh yeah, if we are the first to log the 10 balloon sites, the SCGIS will win a prize of $40,000 which will be used to support the SCGIS International Scholarship Fund. Our participation in this event is strictly for fund-raising purposes, and having some fun as well. Why is DARPA Doing This?: They want to find out how society can mobilize itself using the Internet and social networking tools. We have the answer -- pull together a great group like SCGIS and their friends and put them to the task. Rules/information for the Challenge: . Balloons will go up at 10:00am (ET) (7:00am PT) and be taken down at 4:00 pm local time on Saturday 05 Dec - yes this means they will be visible for 6 hrs on the east coast and 9 hrs on the west coast. . All balloon locations will be visible from a roadway and all areas will be accessible to the public by pedestrian access. Officials will be stationed with the balloons and participants should ask officials for the balloon number and to verify that it is a DARPA Challenge balloon. . Balloons will be visible on 05 Dec ONLY, but we have until noon on 14 Dec to collect the information from our participants. . Federal government employees can not submit locations to DARPA but they can partiticpate in the search for balloons. SCGIS will submit locations for everyone. . The balloons coordinates should be collected in degree-minute-second (DDD-MM-SS) format (latitude/longitude, do not use negative values for longitude). IF you do not have a GPS unit, we have staff available to convert available information (street intersections,...nearby lakes) for you..gather as much information as possible, and be as detailed as possible. See the instructions below for submitting your observation What You Need to Do: Take a walk, go for a jog, hop on your bike, or fire up that hybrid and go for a Saturday drive. If you see a big red balloon that looks like this, take a photo, get an address, and if you are geospatially-enabled, compute a lat-long value that is within 1 mile of where the balloon is. If you have no idea how to determine the latitude and longitude, not prob, just us get an address. There will be a credentialed DARPA staffer at the site so if you are not sure you found a DARPA balloon, just ask. DARPA balloons are also numbered (1-10) and be sure to record this as well. More photos of DARPA balloons can be seen here. Spread the Word: Tell your friends, family, colleagues, and neighbors to be on the lookout for a red DARPA balloon. And tell them you are doing it for SCGIS and their scholarship fund. If they find one, let us know. Here is a sample announcement for your friends, colleagues and family. Reporting Your Observation: We need the following information from you: Participant's Info: Participant's Name: Telephone Number: Email Address: Participant's State: Participant's County: Participant's Town/City: KEY Info: Balloon Number (Balloon number will be clearly visible and is available from the DARPA staff at the balloon site): Street Intersection and City of sighting. Lat/Long of the Balloon (If feasible but not necessary) How the coordinate was derived. A photo (if possible) Brief (few sentences) of the setting of the balloon (any details are valuable) Brief summary of who they heard about this contest from
