Re: [MapServer-users] Python MapScript - GEOS
Thanks Seth,
You are correct. Buffer works and changing the verification line solved
the problem.
Many thanks for your help

Re: [MapServer-users] Python MapScript - GEOS
Hi,
Testing the code here and the following line: shpObjBuffer = shpObj.buffer(
0.0005 ) returns a valid buffered polygon:
>>> shpObjBuffer
>
>>> shpObjBuffer.toWKT()
'POLYGON ((49.965857800020 8.16013072, 49
The buffer method [1] rerturns a new shape, so I'm not sure your check for a
True value makes sense in this line:
if shpObjBuffer == mapscript.MS_SUCCESS:
Are you sure the buffer isn't working?

We're bound to Python 2 (2.7.6) in this case. To refresh, see example

For some reason it looks like for a GetMap request, the line:
content_type = mapscript.msIO_stripStdoutBufferContentType()
results in None, i.e. the headers do not get stripped from the output?
This is the case for either running the script directly as a process
or embedding within Apache
(https://gist.github.com/tomkralidis/9adbd4864c03647aa7eb4f96a3c33297#file-apache-conf)

This results in an immediate prompt to download the result, which is a broken
PNG image with the HTTP response headers still intact, i.e.:
Cache-Control: max-age=86400
Content-Type: image/png
‰PNG

Hi Tom,
adding to Julien's response you could also replace
`request.loadParams()` with
`request.loadParamsFromURL(env['QUERY_STRING'])`.
As Julien said, key is that the environment variables are not set

This answer does not contain any content-type that can be stripped wit

Hi all: we are looking into updating our Python MapScript (CGI-based)

We are using 6.4.2 on Ubuntu 14.04. See example in [1] (against
any mapfile is fine). Simple run with python ./mapscript-wsgi.py
which makes
the server available on localhost:8000 by default.
Issues:

- issuing a, say, WMS 1.3.0 GetCapabilities request yields the
venerable MapServer "This script can " default message, when I am
expecting Capabilities XML
Any ideas what I'm doing wrong here?

Re: [mapserver-users] Python MapScript via WSGI examples
Thanks Julien and Stephan: I've updated my example in [1], however I get
the following traceback when issuing a WMS 1.1.1 GetMap request:
Traceback (most recent call last):
File "/usr/lib/python2.7/wsgiref/handlers.py", line 85, in run
self.result = application(self.environ, self.start_response)
File "mapscript-wsgi.py", line 40, in application
start_response('200 OK', [('Content-type', content_type)])
File "/usr/lib/python2.7/wsgiref/handlers.py", line 180, in start_response
assert type(val) is StringType,"Header values must be strings"
AssertionError: Header values must be string
Any idea?

Re: [mapserver-users] Python MapScript via WSGI examples
Hi Tom, When I run your script, I get the following response: This script can only be used to decode form results and should be initiated as a CGI process via a httpd server. This answer does not contain any content-type that can be stripped with msIO_getStdoutBufferBytes(). That's why it returns None. Before your OWSRequest call, you need to set the Environment variable that MapServer needs. Otherwise they are passed in the env variable and not to MapServer. Code to add: # List of all environment variable used by MapServer mapserv_env = [ 'CONTENT_LENGTH', 'CONTENT_TYPE', 'CURL_CA_BUNDLE', 'HTTP_COOKIE', 'HTTP_HOST', 'HTTPS', 'HTTP_X_FORWARDED_HOST', 'HTTP_X_FORWARDED_PORT', 'HTTP_X_FORWARDED_PROTO', 'MS_DEBUGLEVEL', 'MS_ENCRYPTION_KEY', 'MS_ERRORFILE', 'MS_MAPFILE', 'MS_MAPFILE_PATTERN', 'MS_MAP_NO_PATH', 'MS_MAP_PATTERN', 'MS_MODE', 'MS_OPENLAYERS_JS_URL', 'MS_TEMPPATH', 'MS_XMLMAPFILE_XSLT', 'PROJ_LIB', 'QUERY_STRING', 'REMOTE_ADDR', 'REQUEST_METHOD', 'SCRIPT_NAME', 'SERVER_NAME', 'SERVER_PORT' ] for key in mapserv_env: if key in env: os.environ[key] = env[key] else: os.unsetenv(key) request = mapscript.OWSRequest() Best regards, Julien On 16-07-13 12:55 PM, Kralidis, Tom (EC) wrote: Hi all: we are looking into updating our Python MapScript (CGI-based) wrappers to leverage WSGI, and are having integration issues as part of testing.

[mapserver-users] python-mapscript: layer.getFeature() AttributeError
Hello, I have a problem with the python-mapscript library v6.0.1-2ubuntu1 with swig2.0.4 and python 2.7 installed (I'm running ubuntu 12.04) If the function layer.getFeature is called, I get the following error: File /home/xxx/Documents/xxx_python//src/resdbcore/kaarten/mappreview.py, line 306, in gather_data resultaat = importlayer.getFeature(i) File /usr/lib/python2.7/dist-packages/mapscript.py, line 1192, in lambda __getattr__ = lambda self, name: _swig_getattr(self, layerObj, name) File /usr/lib/python2.7/dist-packages/mapscript.py, line 34, in _swig_getattr raise AttributeError,name AttributeError: getFeature the application runs fine on Windows but I try to get it running on linux with eclipse. the only relevant thing I found is that the layer.getFeature function has been temporarily removed from mapscript but should be available again =6. altough I have swig2 installed, in the file /usr/lib/python2.7/dist-packages/mapscript.py in the head it is mentioned that this file has been automatically generated by SWIG 1.3.36. Could that be the problem, because AFAIK python-mapscript needs swig2? Tim ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users
[mapserver-users] [Python+MapScript] Convert imageObj to PIL Image
Hi All,
I've been testing today in Python, trying to get a MapScript imageObj into an
python Image object. This works via the following code:
map.transparent = MS_ON
map.selectOutputFormat('png8')
map.outputformat.imagemode = MS_IMAGEMODE_RGBA
map.outputformat.transparent = MS_ON
img = map.draw()
mem_png = StringIO.StringIO(img.saveToString())
_img = Image.open(mem_png)
However, the _img file lost its transparency, even though it's still (or again)
PNG. There MUST be a better way of getting the PNG file into PIL, right?
Something besides writing it to a tempfile, opening it, and deleting it?
On a side note, I only use this rendered image temporarily, I only need to cut
it up in smaller bits and return those to my client. So if there's some sort of
format that supports transparcency but without the PNG compression overhead,
that would be even better!
Regards,
Jelmer Baas

Re: [mapserver-users] [Python+MapScript] Convert imageObj to PIL Image
IIRC, PIL does not support 8bit pngs with transparency, so writing it
to a file won't help. If you need alpha, you'll have to stick with
32bit pngs.

Re: [mapserver-users] [Python+MapScript] Convert imageObj to PIL Image
Oh, wow, that was so simple. I changed
map.selectOutputFormat('png8')
to
map.selectOutputFormat('png24')
And done. Strangely, though, saving it to a file and re-opening *does* work!
Thanks for the quick reply!

Hi,
I guess that the mapscript you are using with python is not the proper
one. Did you go to mapserver/mapscript/python and run setup.py install ?
Note that integration of agg in python-mapscript is not trivial due to
some limitations in the agg lib.

[mapserver-users] Python mapscript: inline point feature How To
Hi Everyone, A little while ago, Brent Fraser sent me a mapfile snippet that could be used to add a Title to a map using pixel coordinate space. It looked like this: LAYER NAME title STATUS DEFAULT TRANSFORM FALSE TYPE ANNOTATION FEATURE POINTS 4 396 END TEXT 'This is a Great Map!' END CLASS LABEL TYPE TRUETYPE FONT arial SIZE 8 ANTIALIAS COLOR 255 255 255 POSITION UR END END END This works well, but I would like to override the TEXT value using mapscript to create new labels that are based on the result of PostGIS queries. I've been picking apart various examples on the web, but can't seem to come up with the magic sauce. I can figure out how to grab the layer ByName, but then I'm not quite sure what I need to do in order to access the feature and override the TEXT. Can someone give me a clue?

[mapserver-users] Python mapscript, cStringIO, and the AGG renderer
Hi All, I'm having problems using the AGG renderer with Python mapscript. I believe it may be due to the way in which I am writing the image into a cStringIO.StringIO() object, but I'm not sure. I do know that if I comment out my OUTPUTFORMAT section of the mapfile, I get an image back in my browser. I'm hoping I can fix this somehow with a FORMATOPTION. - Below is the mapscript and Python CGI: #! /usr/bin/python import mapscript import cStringIO def DrawMap(): mapfile = /var/www/mapfiles/gis_layers/gis_layers.map mapobject = mapscript.mapObj(mapfile) mapimage = mapobject.draw() f = cStringIO.StringIO() mapimage.write(f) print Content-type: image/png\n f.seek(0) print f.read() print mapimage if __name__ == __main__: DrawMap() - And here is the OUTPUTFORMAT section that's causing the problem: OUTPUTFORMAT NAME 'AGG' DRIVER AGG/PNG IMAGEMODE RGB END Thanks, Roger -- ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users

Re: [mapserver-users] python mapscript - creating vector symbols on the fly?
David, after a quick look it seems that the API is there, although I am not entirely sure whether it is stable or tested. in pseudocode: symbol=new symbolObj() //set attributes of symbol map-symbolset.append(symbol) Regards, Umberto On Wed, Sep 24, 2008 at 10:09 PM, Fawcett, David [EMAIL PROTECTED] wrote: In Python mapscript, is it possible to construct a vector symbol, like a circle, without referencing a mapfile or a symbolset file?
