You might have to make explicit conversion maually something like:

            string value = "لققافعععىىةةونه"; //I actually get this (in arabic) through user input
            byte[] bytes = Encoding.Convert(Encoding.Unicode, Encoding.GetEncoding(1256), Encoding.Unicode.GetBytes(value));
            StringBuilder s = new StringBuilder();
            for (int i = 0; i < bytes.Length; i++)
                s.Append(Convert.ToChar(bytes[i]));
            shpObj.text = s.ToString();

Best regards,

HI 

 

I am doing a simple thing. I have a map file and trying to show some static text in Arabic on map. You can try this with any map file as it is nothing to do with layers from map.

 

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.

 

Thanks

Murty

Please send me your example so that I could examine what's going on.

Hi

 

I tried with the suggested encoding but still no success.

>From the output below, I guess ICONV support is included.

 

E:\Utils\MapServer\Map Server 5.2 RC\ms4w\Apache\cgi-bin>mapserv -v

MapServer version 5.2.0 OUTPUT=GIF OUTPUT=PNG OUTPUT=JPEG OUTPUT=WBMP OUTPUT=PDF

 OUTPUT=SWF OUTPUT=SVG SUPPORTS=PROJ SUPPORTS=AGG SUPPORTS=FREETYPE SUPPORTS=ICO

NV SUPPORTS=FRIBIDI SUPPORTS=WMS_SERVER SUPPORTS=WMS_CLIENT SUPPORTS=WFS_SERVER

SUPPORTS=WFS_CLIENT SUPPORTS=WCS_SERVER SUPPORTS=SOS_SERVER SUPPORTS=FASTCGI SUP

PORTS=THREADS SUPPORTS=GEOS SUPPORTS=RGBA_PNG INPUT=JPEG INPUT=POSTGIS INPUT=OGR

 INPUT=GDAL INPUT=SHAPEFILE

 

Where can get some details on how to build the C# mapscript (Managed assembly only) from Visual Studio, keeping all unmanaged dlls from binaries from ms4w. I just want to give a try using MarshalAsAttribute.

 

Thanks

Murty

Hi,

You might want to try with encoding="ISO-8859-6" assuming you have libiconv compiled in.
The c# mapscript doesn't specify explicit conversion during the marshaling. In this case I assume an unicode to Charset.Ansi conversion will automatically takes place by default.

Hello 

 

I am having some issues using Arabic text as labels. I am using C# map script. I am setting the following at runtime

 

labelObj label = classObj.label;

label.encoding = "CP1256";

label.text = "some text in Arabic"; (At rune time in VS, I can see the text is actually in Arabic)

 

But labels are displayed as '?????'.

 

 Is there any conversion I need to do before setting the text value. How are the string represented in the underlying mapscript dll (ASCII or Unicode?). As I was reading in the MSDN, the default marshalling uses LPStr which is a single byte of ASCII. Does it mean that first I need to convert from Unicode to ASCII in C# before setting the value.

 

Appreciate any help.

 

Thanks

Murty
