RE: [mapserver-users] C# query method
Hi Steve/Tamas Until now I was under the impression that I can't do a query by attributes and shape in a single call. Hence I had written my code first to execute query by shape and append those results to query expression as IN clause and invoke queryByAttributes. While doing some testing on oracle spatial layer, I found that queryByShape is actually honoring filter expression on the layer. Since this will be executed as a single call, I want to modify my code to call only queryByShape and set the query expression to filter. This will improve overall time taken for the query execution but I want to make sure that his behavior is consistent across all data sets (providers).

RE: [mapserver-users] layer.whichShapes() in C# mapscript
Hi Tamas,
Thanks for your response. I don't have the latest. But, as a workaround,
I have done the same fix in my code i.e. backup the connection type and
change the connection type to MS_INLINE just before calling
whichShapes(). After the change, it is retrieving the attribute values.
Appreciate your help.

I suspect you've run into the following issue here:
http://trac.osgeo.org/mapserver/ticket/2689
which have already been fixed in:
http://trac.osgeo.org/mapserver/changeset/9060
http://trac.osgeo.org/mapserver/changeset/9064
Make sure your version is newer than the changesets above.
By using this fix you won't need to call layer.open right after
whichShapes in order to retrieve all the items.

Hi
I am having difficulty performing layerObj.whichShapes() and looping
through results. For some datasets like shape files, it requires
layerObj.open() call after invoking whichSpaes(). Otherwise,
shapeObj.values.length is 0. For ArcSDE, it throws an error on
layer.nextShape() if layer.open() is called after invoking
whichShapes(). How to write a single piece of code that works with all
datasets without checking for layer data source type? Here is the simple
test code I am using
layerObj layer = m_map.getLayerByName("Roads");
if (layer != null)
{
layer.template = "abcd";
if (layer.open() ==
(int)MS_RETURN_VALUE.MS_SUCCESS)
{
if (layer.whichShapes(m_map.extent) ==
(int)MS_RETURN_VALUE.MS_SUCCESS)
{
layer.open(); //Required for shape
files. Otherwise, shapeObj.values.length will be zero.
shapeObj shape = null;
while ((shape = layer.nextShape()) !=
null)
{
if (shape.values != null &&

{

}
}
}
}

}

[mapserver-users] queryByAttributes on oracle spatial layer
Hi I am doing a query on a oracle spatial layers. When I loop through the result set to retrieve field value, using layerObj.getFeature() method, it is terribly slow. What I see from the log files is that a separate database query with unique id column value is fired to oracle for each getFeature call. This will definitely slows down. If I have 10,000 results, then 10,000 database queries are getting fired to retrieve the field values. Is there is a way to avoid this. Is there any setting or API that will prevent so many separate queries fired and retrieve field values with first query itself.

Hi Where can I get the list of valid encodings that can be used in encoding of LABEL section. Thanks Murty ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users
RE: [mapserver-users] Encoding issues
Hi
As per the code documentation in the method msGetEncodedString (as shown
below), the characters are assumed to be UTF-8 by default.
char *msGetEncodedString(const char *string, const char *encoding)
{
---
if (len == 0 || (encoding && strcasecmp(encoding, "UTF-8")==0))
return strdup(string);/* Nothing to do: string already in UTF-8 */
Where as in the ‘values’ property of shapeObj.cs in C#, it is using
System.Runtime.InteropServices.Marshal.PtrToStringAnsi (to marshal characters
from c to c#). Shoudn’t it be using
System.Runtime.InteropServices.Marshal.PtrToStringUni method since as the
charcters are by default held in UTF-8 encoding?
Thanks

Hi,
I don't know much about the hindi character sets.
I guess you could extent that byte array to string copy function with arbitrary
character sizes, like for double bytes something like:
for (int i = 0; i < bytes.Length; i=i+2)
s.Append(Convert.ToChar(bytes[i] + 256*bytes[i+1]));
Best regards,

Hi Tamas
This is still not working for some of the Asian languages.
I suspect the issue could be in this line of your sample code below
s.Append(Convert.ToChar(bytes[i]));
Here, one single byte is used to convert to a character. But my understanding
is that UTF-8 can consume from 1 to 4 bytes to represent one character code
point. It worked fine for Arabic may be because all Arabic characters can be
represented using a single byte.
When I tried the same code below with Hindi, an Indian language, some of the
characters are shown junk (but not all characters). I guess those characters
which occupy more than a byte turned out to be junk.
I am also trying the opposite of the sample code below i.e. read a field value
from map server (shapeObj.values), which is in Hindi, and show on a web page,
again it turns out to be junk. I tried to look at the byte values of the string
in VS by using
Byte[] bites = Encoding.Unicode.GetBytes(shapeObj.values[0])
I notice that they are actually code point of UTF-8 but interpreted as UTF-16
and may be the reason I see junk characters on web page. But I don’t know how
to extract those UTF-8 byte values from UTF-16.
I am just giving sample code here to explain
byte[] utf16 = Encoding.Unicode.GetBytes("कीचनर"); //The text
is in Hindi, an Indian language
byte[] utf8 = Encoding.UTF8.GetBytes("कीचनर");
shapeObj shape = layer.getFeature(result.shapeindex,
result.tileindex);
string value = shape.values[1]; //This contains the same text
(in Hindi) as above in the shape file.
byte[] bytes = Encoding.Unicode.GetBytes(value); //There are
byte values of characters decoded from UTF-16. .Net internally stores all
strings in UTF-16
Now if I examine the values of ‘utf8’ and ‘bytes’ arrays
utf8 – 224,164,149,224,165,128,224,164,154,224,164,168,224,164,176
bytes –
224,0,164,0,34,32,224,0,165,0,172,32,224,0,164,0,97,1,224,0,164,0,168,0,224,0,164,0,176,0
utf16 – 21,9,64,9,26,9,40,9,48,9
The first byte value is same as UTF-8. Second byte value is 0 as UTF-16 takes
atleast 2 bytes for a character. This gives me impression that the byte values
are in UTF-8 and are not converted to UTF-16 to by .Net.
Appreciate if you see any solution for this and let me know.

[mapserver-users] mapscript question
Hi What is the best way to retrieve all records of a layer. Some options I see is 1. calling queryByRect(mapObj.extents) - But this will not get all records if map extents are smaller than layer extents 2. layer.whichShapes() - But this will apply filter set on the layer. I want to get all records. 3. call queryByAttribute() and pass some expression that will select everything Or, is there any more straight forward API to get all records.

Hi I am setting font property at runtime using clsObj.label.font="Times-New-Roman" This font alias is there in my fonts file. When I save the map file (mapObj.save()), the font name is not saved. It saves the font name if the type is set to truetype. If the type is set to bitmap, then it is not saving the font name. Does it not support using a font if the type is bitmap.

This is the WMS server url http://www2.demis.nl/wms/wms.asp I have used a layer called Countries from that server and this is the capability xml for that layer Countries Countries This is the entry in map file LAYER CONNECTION "http://www2.demis.nl/wms/wms.asp?wms=SAMPLE&"; CONNECTIONTYPE WMS METADATA "wms_srs""EPSG:4326" "wms_name" "Countries" "wms_format""image/png" "wms_server_version" "1.1.0" END NAME "Countries" PROJECTION "init=epsg:4326" END STATUS ON TYPE RASTER UNITS DD END I get extents values (minx, miny, maxx and maxy) as -4.8366978272229995E-26 (which is not same as above in the capabilities xml) Appreciate any help.

RE: [mapserver-users] WFS Layer + C# map script
Hi Assefa Yes, the problem seems to be related to the GML file not accessible. I normally leave WEB->IMAGEPATH empty in my map files as my application displays map image on a windows form directly. When I started adding support for WMS layers, I noticed that it is using imagepath to store temporary files. I didn't want to specify a qualified path as the map file will not load on other machines which may not have the same path. I tried "\" (after briefly scanning through msBuildPath and msBuildPath3 methods) and it worked for WMS. I guess "\" gets resolved to location of the map file. But same is not working for WFS. If I change the path from "\" to a fully qualified path, I don't see that error any more. But I don't want to use fully qualified path. I want to use any relative path that can be resolved to map file path or shappath or any other location. What is the best relative path I can use for imagepath that can work for WMS/WFS or any other data sources that use this to store temporary files.

This GML file is saved locally and rendered by OGR as a vector layer. You might want to check the file you got from the server (should be inside web.imagepath (.tmp.gml) and see if it is valid or/if can be opened with ogr.

After firing queryByShape() on SQL Server 2008 layer, getting junk
characters for those field which are null (or have no value) in the
database. Shows fine for those fields with some value.
When I run any sample query on the table in query analyzer, I see the
output as {null}.
If the value is null in the database, I should be getting null reference
or empty string (using C# map script i.e. shapeObj.values). Why I am
getting junk characters.
Appreciate any help.

Hi Brian I had verified my code and there is no issue setting the units correctly in C#. In fact, I see the same issue setting the units to feet in map file directly.

Be sure you are setting the scalebar units member accordingly in C#. For example, scalebar.units = (int)OSGeo.MapServer.MS_UNITS.MS_FEET to set the units to feet. However, I have noted that it will appear garbled and squashed in width if you use units which are not meaningful for the current zoomed area. In other words, don't use inches when zoomed to a city or world view...the numbers are too large to display properly. Write a routine that sets the appropriate units based on the delta degrees that you are showing. For example, if the user chose English units (versus metric) and the current viewport spans roughly ~0.5 nautical miles, then set the units to inches. If the viewport is > 0.5 NM and < 1 NM, set the units to feet. Otherwise (the viewport spans more than 1 NM), set the units to miles. You can tweak this idea to suit your needs but this works well for me.

At run time (like on a button click), please add this layerObj lyr = new layerObj(mapObj); lyr.name = "TextAcetate”; lyr.status = mapscript.MS_ON; lyr.type = MS_LAYER_TYPE.MS_LAYER_ANNOTATION; lyr.labelcache = mapscript.MS_TRUE; double locationX = 50; double locationY = 50; lyr.transform = (int)mapscript.MS_FALSE; classObj layerClass = new classObj(lyr); //All label properties layerClass.label.size = 15; layerClass.label.type = MS_FONT_TYPE.MS_TRUETYPE; … … layerClass.label.encoding = “CP1256”; shapeObj shpObj = new shapeObj((int)MS_SHAPE_TYPE.MS_SHAPE_POINT); lineObj lnObj = new lineObj(); pointObj pt = new pointObj(locationX, locationY, 0, 0); lnObj.add(pt); shpObj.add(lnObj); shpObj.text = “لققافعععىىةةونه”; //I actually get this (in arabic) through user input lyr.addFeature(shpObj); mapObj.draw(); //Onto a picture box or save as file (In the map file, my output format is set to GD/PNG) Please let me know if you need more information.

[mapserver-users] Junk text field values for ArcSDE layers
Hello I am having some issue with attribute (field) values for ArcSDE or Oracle Spatial layers. All text field values are becoming junk characters (after calling queryByRect() method). I am using C# map script and VS 2008. This is happening for text fields. Number and date fields seems to be fine. Is there any special encoding I need to handle in .Net when values are retrieved (shapeObj.values)? Same field values looks fine in ArcIMS and ArcMap.

RE: [mapserver-users] queryByRect throws an error
Hi Tamas
Yes, there is a workaround to prevent this issue. I am already taking
care in my code.
Thanks

Subject: Re: [mapserver-users] queryByRect throws an error
Hi Murty,
Yes, you're correct. By setting the template parameter of these internal
layers like __embed__legend or __embed__scalebar causes the behaviour
you've reported before. However I'm not sure it should be denoted as a
bug since you could easily skip setting these parameters in your code.
Skipping these layers in the mapserver query code may cause slower
execution which is undesirable in most cases. I'm guessing there might
be some other occurrences where altering these special layers in
mapscript may also cause unexpected results.
Best regards,
Tamas

Hi Tamas
Thanks for reply.
These are extracts from my code to replicate the issue
//Create map object
mapObj map = new mapObj("MyMap.map");
//draw map
map.draw() ;
//Make sure some template name is defined. Otherwise, query will not be
successful.
for (int i = 0; i < map.numlayers; i++)
{
if (string.IsNullOrEmpty(m_map.getLayer(i).template))
{
m_map.getLayer(i).template = "abc";
}
}
//Perform the query now
map.queryByRect(map.extents);
I think after a call to map.draw(), a new layer '__embed__scalebar' is
added to layers collection. Setting template name to it is performing
the query on scalebar layer as well.
I think the scalebar layer is not satisfying these two conditions in
msQueryByRect method of mapquery.c and hence getting used for query
if(!msIsLayerQueryable(lp)) continue;
if(lp->status == MS_OFF) continue;
Please let me know if you need more info or you need any test
application.
Thanks

Hi,
Could you provide a code/mapfile sample to reconstruct the issue? I've
never experienced such a problem, I've used this function many times
though.

mapObj.queryByRect(...) (using C# map script) is throwing following
exception when there is an embedded scale bar on map.
Exception message: "msShapefileOpen(): Unable to access file. No (NULL)
filename provided.;msBuildPath: Unable to access file"
Removing the scale bar from map file works fine.

[mapserver-users] Clear projecton from layerObj
Hello
How to remove (or clear) a projection information set to a layer using
C# map script. For example, I have set a projection information to a
layer using the code
layerObj.setProjection("init=EPSG:4326");
Now I want to clear this projection and set the layer to its original
(unknown )status. I don't find any API on the layerObj to clear the
projection information.

[mapserver-users] Exception using oracle spatial layer
Hello Users I am getting an exception when using oracle spatial layer. I am setting filter expression to the layer at run time(using C# map script, layerObj.setFilter()) and when I call draw() method on map after setting the filter, the following exception is thrown msDrawMap(): Image handling error. Failed to draw layer named 'Ward'.;msOracleSpatialLayerWhichShapes(): OracleSpatial error. Error: ORA-21710: argument is expecting a valid memory address of an object. Filter expression is very simple - 'WARDID in (1,2)'. The field and the values both exist on the layer. It works fine (i.e. image is generated) when I don't set the filter.

[mapserver-users] setConfigOption is not working
I am trying to set a CONFIG option (using C# mapscript ) but it doesn't
seems to work.
In the map file (under layer block), I have set 'PLUGIN' parameter to
the name of the DLL (without fully qualified path). I want to set the
path prefix (MS_PLUGIN_DIR) at run time.
Here is the C# code I am using,
mapObj map = new mapObj("C:\\mymap.map");
map.setConfigOption("MS_PLUGIN_DIR", "C:\\my_plugins");
map.applyConfigOptions();
imageObj image=map.draw();
It is not loading the plug-in DLL. If I set this CONFIG parameter
directly in the map file, it works fine. Also, when I debug and check
the value of 'plugin_library' on layerObj, it does not contain the
prefix of plug-in directory.
Did anyone had the same issue? Am I missing any steps here.
Appreciate any help.
Thanks
Murty
