Re: [mapserver-users] Mapscript C# and OWSRequest parameters
Hi all,
Well, that route was a short one. Yes, I can call installStdinFromBuffer, but
actually reading something via bufferRead:
int msIO_bufferRead( void *cbData, void *data, int byteCount )
{
(void)cbData;
(void)data;
(void)byteCount;
/* not implemented yet. */
return 0;
}
Unless I’m missing something, this isn’t possible, yet. I find it hard to
believe no-one uses MapServer to handle WFS Post requests, so I’m pretty sure
I’m missing something?

Jelmer Baas

Hi Jelmer,
I think you'd have to use mapscript.msIO_installStdinFromBuffer to read data in.
See https://mapserver.org/development/rfc/ms-rfc-16.html#io-hooking although
I'm not sure if the approach works or was fully implemented.
Let us know how you get on,

Re: [mapserver-users] Annotation label with styleitem auto uses bitmap font
Update on this issue: MapInfo didn't have a font specified for the TEXT objects. This meant that MapServer somehow didn't use the fallback font (default), but switched to its built-in font. I've now manually changed all fonts to Arial, added a valid default font in my fontset, and it works! (And it looks beautiful :) For short-term, I'll make sure our conversion software adds a valid font, but I would like it if someone can investigate this further (MID/MIF or TAB file available on request), since it's odd behavious imho.

[mapserver-users] Annotation label with styleitem auto uses bitmap font
Hi all, I have some converted AutoCAD files in MapInfo format that I'm showing via MapScript (up-to-date, via apt get). To show all components, each TAB file has both a 'line' layer (styleitem auto) and an 'annotation' layer (also set to styleitem auto). This has worked fine for ages, but there are two issues: - Special characters aren't displayed - We now have a new file, which has an odd font size Because of this new file, I'm beging flooded with this message: msGetRasterTextBBox(): General error message. selected renderer does not support bitmap font size 13 Both issues obviously mean MapServer is using its built-in bitmap font. Is there a way to override this? I've tried a few options already: - Switching to PNG instead of GIF output format - Setting class.label properties; this has been removed in 6.2 - Creating a new labelObj, and adding it via class.addLabel; this manages to crash my python script (not getting caught in try/catch) without leaving any logs when styleitem is still set to auto - Adding a default and Arial entry in my fontlist file. This seems to be ignored. Furthermore, I can't seem to get ANY logging from MapScript. I've tried setting debug to MS_TRUE in the layer, mapfile, class, etc. Log file is being created (in /tmp) but remains empty. Am I doing something wrong? Missing something? Any help would be greatly appreciated! Regards, Jelmer ___ 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!

Jelmer Baas

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.

[mapserver-users] Itemnquery slow in big TAB file; slow on Oracle as well
Hello List,
I have a query to retrieve geometry from a TAB file:
mapserv.exe?mode=itemquerymap=
query.mapmapext=-7+28+50+70layers=MYLAYERqlayer= MYLAYER
qstring=('[IDCOLUMN]' IN '2550643')
This is my simplified Layer definition:
LAYER
NAME MYLAYER
TYPE LINE
CONNECTIONTYPE OGR
CONNECTION c:\temp\MYLAYER.TAB
CLASS
NAME Test
END
METADATA
qstring_validation_pattern '^'
END
END
To query this TAB file, MapServer needs about 20 seconds. MapInfo needs about
20ms, so MapServer is obviously not using the index on this column.
I tried changing this to Oracle Spatial, but then I bump into another problem:
the query contains a spatial clause (which isn't needed):
SELECT IDCOLUMN FROM MYLAYER WHERE 'IDCOLUMN' IN '2550643' AND SDO_FILTER(
GEOLOC, MDSYS.SDO_GEOMETRY(2003, 90112,
NULL,MDSYS.SDO_ELEM_INFO_ARRAY(1,1003,3),MDSYS.SDO_ORDINATE_ARRAY(-7,28,50,70)
),'querytype=window') = 'TRUE'
This also takes about 10 seconds. Without the AND SDO_FILTER() part it takes a
few milliseconds.
So two questions, I guess. Can I make MapServer use the index on the IDCOLUMN
column, and, can I tell Mapserver to skip the SDO_FILTER part on Oracle?
Oh, I'm currently using MapServer 5.6 but tried 6.0 as well.
Thank you,

Hi,
You can also try to add this to LAYER
wfs_extent
Description: (Optional) Used for the layer's BoundingBox tag for cases
where it is impossible (or very inefficient) for MapServer to probe the data
source to figure its extents. The value for this metadata is minx miny maxx
maxy separated by spaces, with the values in the layer's projection units. If
wfs_extent is provided then it has priority and MapServer will NOT try to
read the source file's extents.
And of course you should always be the boss and test with the basic hand
written requests first before letting the GIS client to add for the
complexity.
Something like these:

Subject: Re: Error with WFS request from MapInfo
Hi,
I would start by addind EXTENT to MAP level. WFS 1.0.0 does
not support
reprojection so select the desired output srsName and use
that as map level
PROJECTION. Express extents to suit that projection.
Mapserver has been pretty poor WFS server for real GIS
clients but it is
getting better. However, I cannot promise you any amazing
interoperability.
At least I would recommend you to update to 6.0. If you
want to get some
good feelings about WFS consider having a try with TinyOWS
first. It works
only with PostGIS (v. 1.5 or higher) but that looks to be
OK for you. I have
managed to read features from TinyOWS with Kosmo GIS,
gvSIG, QGis, uDig,
ArcGIS, MapInfo, Gaia, SIS Map Browser and iGeoDesktop.
With some clients
even attribute and spatial filters work. Come back to
Mapserver WFS later
and start making bug reports. Glad that you learned already
to study the
POST traffic, it is really a must with WFS debugging. I am
using Fiddler for that
purpose.
MapInfo seems to send a most basic WFS call (or stupid,
just orders the
whole layer from you) so that should not be a trouble in
this case. Once you
get the extents corrected you can continue and wait excited
if MapInfo will
have troubles with checking the schemas and parsing the GML
that comes
from Mapserver.

Tamas, Thanks for the reply. This setting does indeed work, however: you still need to define a (empty) class for the layer, otherwise it’s simply invisible. Might I suggest documenting this?

RE: [mapserver-users] MapServer, WFS and Oracle
Michael, Thanks for the tip. Indeed, I still need to add these tags, but since my dataset wasn't working at all, I didn't do anything with that, yet. Right now the query takes 16-20sec, so some optimization is in order. Regards, Jelmer Jelmer, Also, when using WFS from Oracle, you should add the wfs_extent or ows_extent metadata tags. Otherwise MapServer will request Oracle to do a convex_hull to get the extent of your data. On large datasets, this can take a while. Setting the extent metadata tag bypasses this check and uses the value you specify. ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users

The request layer is the combination of all your layers, the overlaying is made server side. Details: 1. We have a custom layer switcher that user selects what layers he wants to see and this data is saved, in a php session for example. 2.

Dan, Thank you for your reply, unfortunatly this is not an option due to the large ammount of different styles we (need to) use. Plus, with TAB or Shapefiles each filter slows down map rendering. Tamas, Thanks a lot! At the moment I'm using MapServers' own Oracle interface, but I'll switch to OGR and give it a shot. It looks exactly like what I need. Might I suggest adding a link to http://www.gdal.org/ogr/ogr_feature_style.html in some MapServer pages (even though it's technically an OGR thing, I think it's information that will benifit many more MapServer users).

RE: [mapserver-users] Oracle Spatial and styleitem auto
Tamas, Thanks to your url I managed to get it working. The performance is way better than I hoped! The only thing that doesn't seem to work is linewidth for (poly)lines. The style PEN(w:8px,c:#FF6A00) still draws a 1 or 2 pixel line. I tried using cm, pt, etc, but that doesn't change anything. I don't have a style in my map file that overrides it, too (only a class with name and template). Any ideas? Or should I ask this question in a gdal/ogr list? Regards, Jelmer Baas From: Tamas Szekeres [mailto:szeker...@gmail.com] Sent: zaterdag 23 mei 2009 0:30 To: Jelmer Baas Cc: mapserver-users@lists.osgeo.org Subject: Re: [mapserver-users] Oracle Spatial and styleitem auto Hi, If you are using OGR to access the Oracle Spatial data source, you could specify a valid OGR style string in the table by adding field with name: 'OGR_STYLE'. In this case OGR will extract the feature style automatically when using the STYLEITEM AUTO option with this OGR layer. For more information about the OGR feature style strings see: http://www.gdal.org/ogr/ogr_feature_style.html You could use ogr2ogr to transfer the feature styles between various data sources, see the document above.

RE: [mapserver-users] MapScript and ZoomRectangle (and rectObj problems)
Jim, List,
Thanks for the reply. I'm afraid that eventually I'll be working with
more than one coord system, so I don't believe your solution can work
for me.
I've been continueing my testing, and it seems like all MapScript zoomto
functions either work unlike I expect them, or are completely broken. I
tried to following:
In the immediate pane in VB .Net:
? map.setCenter(new pointObj(143000,485437,0,0))
0
? map.extent
{OSGeo.MapServer.rectObj}
maxx: 143397.59497452341
maxy: 485654.62790724094
minx: 142602.40502547659
miny: 485219.37209275906
This seems to work properly. Now the following:
? map.zoomScale(1000, new pointObj(143000,485437,0,0),mapwidth,
mapheight,map.extent, nothing)
0
? map.extent
{OSGeo.MapServer.rectObj}
maxx: 225008.64025899942
maxy: 207042.5828362515
minx: 224520.10434931691
miny: 206775.17742509485
When I change map.extent to fullExtent (which is set after loading, in
this case the extents of the Netherlands)
? map.zoomScale(1000, new pointObj(143000,485437,0,2),mapwidth,
mapheight,FullExtent, nothing)
0
? map.extent
{OSGeo.MapServer.rectObj}
maxx: 85315130.06053336
maxy: -353386875.22545278
minx: 85314641.524623737
miny: -353387142.6308639
These numbers are completely unexpected. Even though I'm not sure about
the zoomscale of 1000, the extent returned doesn't make any sense.
MapWidth = 1384. mapHeight = 758
This is really a huge problem for us at the moment. I hope someone can
shed some light on this.
Thanks in advance,
Jelmer Baas

[mapserver-users] MapScript and ZoomRectangle (and rectObj problems)
Hello List, Three years ago, I built a web interface for our primary application using MapServer. Now we're in the process of building that same application in VB.Net (but with more features) using MapScript. Although everything comes along nicely (I love the fact that everything returns objects, etc) there is one huge problem that I can't seem to solve: creating and using the rectObj class. I read a lot about it and found many bug cases, older messages, etc, but I still can't make heads or tails of it. I'm sorry about asking it, since it must be the millionth time this question has been asked. I *CAN* get ZoomRect with a rectObj to work when using image coords, even though that requires my own code that flips miny and maxy to solve that lovely error about miny = maxy or something. When I try to use it with map coords however, I can't get it to work. In my init code I create a new rect object: Map = New mapObj(strMapPath) FullExtent = New rectObj(0, 0, 0, 0, 0) With Map.extent FullExtent.maxx = .maxx FullExtent.minx = .minx FullExtent.maxy = .maxy FullExtent.miny = .miny End With When I feed this to ZoomRectangle using Map.zoomRectangle(FullExtent, MapWidth, MapHeight, Map.extent, Nothing) I get that famous mapscript::mapObj::zoomRectangle(): General error message. image rectangle maxy = miny. When I flip miny and maxy I end up in the middle of the Sahara (while the original coords should show the Netherlands). Things I wonder about: 1) How can I get zoomRectangle to work with world/map coords instead of image coords? 2) Why does the constructor have an imageunits as integer? IMHO a simple rect object has nothing todo with the coordsys of the/a map (since I can more than one). 3) When will the much discussed bugfix be applied that automaticly flips miny/maxy? Any help would be greatly appreciated, With kind regards, Jelmer Baas ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users
