Re: [mapguide-users] Memory Leak in Java
Hi Benoit Your hint is helpful: I tried with a smaller buffer (1024) and the leak is greatly reduced so the dimension of buffer is somehow involved. Still the leak remain. There is some memory allocated by c++ that is not freed. That memory is off of the java heap, so it cannot be directly managed by garbage collection.

[mapguide-users] MSSQL Provider
Hi all We have a customer where sometimes happens that network connection between servers where mapguide and database are installed gets lost. After connection is reestablished (maybe some milliseconds after) We got this error from provider: RDBMS: [Microsoft][SQL Server Native Client 10.0]SMux Provider: Physical connection is not usable [x]. (Cause: , Root Cause: RDBMS: [Microsoft][SQL Server Native Client 10.0]SMux Provider: Physical connection is not usable [x]. ) Obviously is not a mapguide problem, but when it happens the only thing we could do is restart the mapguide server service. Others connection pool technologies (java common-dbcp for example) have an option to check if the connection is valid after borrowing it from the pool, by making a validation query like: "select 1". If the test is not positive the connection is removed from pool and another one is borrowed. Is there something analogous in MapGuide/Fdo, or someone knows any workaround to avoid manual intervention after this problems? Thanks!

Re: [mapguide-users] What Java version is needed for Mapguide 3.0?
Hi
1) Check if MapGuideJavaApi.dll is in java.library.path (on Windows the
easiest way is put MapGuideJavaApi.dll directory in system path).
2) Check if JVM and Mapguide are both 64 bit (or both 32bit)
Remember that if MgInitializeWebTier call fails the first time, any other
subsequent call do nothing, and the MapguideApi.jar is not loaded in
classpath, so any reference to a class inside the jar will throw a
ClassNotFoundException.

Re: [mapguide-users] MapGuide Java vs PHP
Hi Farhan, I use java api daily without problems. Basically there are no difference between :net, php and java api because Mapguide has a single C++ server side api, exposed via swig to the three high level languages. For that reason documentation and samples are valid for the 3 languages. The real choice that matters is the client viewer technology you want to use: 1) Ajax viewer: you can use php, .net and java for customization. From java point of view you are limited to jsp only programming (no servlets, no frameworks).. not very comfortable. 2) Fusion viewer: only php available for customization. 3) Build your own openlayers based viewer. Much more effort but no restriction. My 2 cents: if 1) or 2) match your needs with little customization, go for it and use php for portability. If you plan to do many changes or map viewer is just a small piece of your whole project go for 3) with technology you are most productive for you.

Re: [mapguide-users] Centos Mapguide 2.6 Oracle provider missing
I'm pretty sure is Linux-wide. It depends on sizeof wchar_t which is compiler specific: on Windows (visual c++) is 2 byte while on Linux (gcc) 4 byte. When Haris switched from UTF-8 to UTF-16 charset to perform oracle connection, used wchar_t to pass/retrieve string to oracle. In windows it's ok because UTF-16 and wchar_t have the same size, in Linux a shrink/deflate should be performed each time there's need to copy data from/to wchar_t array to/from the UTF-16 array, as some OCI wrapper does. (OCILIB for example). I tried in the past to modify the provider in a such way, but I never been able to have a fully functional provider, and finally I gave up.

[mapguide-users] Rasterlite file on MGOS
Hi All, I successfully managed to connect MGOS to a rasterlite db using FDO GDAL Provider. Rasterlite is a library designed to give fast read access to large raster dataset. Data are stored in a sqlite db. When loaded into the db, raster are automatically tiled and pyramidal set of overview can be built. Follow the link below for better explanation. http://www.gaia-gis.it/spatialite http://www.gdal.org/frmt_rasterlite.html Since GDAL Provider shipped with MGOS is not built with rasterlite support, I have followed the instruction to add ECW, MrSID as per http://trac.osgeo.org/mapguide/wiki/MGOS22GdalProvider Since I tested it with MGOS 2.5 I grabbed the needed dll from: http://www.gisinternals.com/sdk/PackageList.aspx?file=release-1600-gdal-1-9-0-mapserver-6-0-1.zip If you want to give it a try you can use the gdal utilities to create a new rasterlite db (from a large geotiff for example): gdal_translate -of Rasterlite yourfle.tiff RASTERLITE:filename.sqlite,table=source -co DRIVER=JPEG -co BLOCKXSIZE=1024 -co BLOCKYSIZE=1024 -co QUALITY=100 gdaladdo RASTERLITE:filename.sqlite,table=source 2 4 8 16 After that you just have to create a new GDAL feature source using Maestro and select the newly created sqlite file. I made a little test with a small (2x1) jpeg, performance are nearly 10 times better compared with original raster used as is.

Check inside serverconfig.ini (on the server): the MachineIp and

For example if on serverconfig.ini you have 127.0.0.1 you should change

I am developing a application using Fusion and .NET. When the application is
installed at the server everything works fine, but if I try to run the
application from my workstation Fusion recieves a html response Cannot
establish connection to the Infrastructure Map Server as shown below. The
webconfig.ini is pointing to the right server IP address at
SiteConnectionProperties (IpAddress=192.168.177.128).
If someone can help, I appreciate.
var appDefUrl = Fusion.getQueryParam('ApplicationDefinition');
if(appDefUrl (
appDefUrl.indexOf('Library') == 0 ||
appDefUrl.indexOf('Session') == 0)){
var passedSessionId = Fusion.getQueryParam('Session');
if(passedSessionId == null || passedSessionId == ){
createSessionId(Fusion.getQueryParam(Username),
Fusion.getQueryParam(Password));
}else{
Fusion.sessionId = passedSessionId;
}
var xhr = new getXmlHttpRequest();
var mapAgentUrl = getAgentUrl();
xhr.open(GET, mapAgentUrl +
?OPERATION=GETRESOURCECONTENTVERSION=1.0.0LOCALE=enCLIENTAGENT=MapGuide+DeveloperRESOURCEID=

xhr.send(null);
// The error is here ***

Re: [mapguide-users] Advanced Stylization labelling
I have (sometime) used AS in my projects. From what I have understood, it's not correct to talk about labeling with A.S., but more exactly you can use text to stylize features. Text became part of the main feature style (for example text can be part of the selection blue shape), and position, rotation and all other text properties are calculated by evaluating style rules for points, lines, and area and only by that. So if you want fine grained control on label text position, rotation, etc AS is good. In contrast, interference between two text are not evaluated (AFAIK), and, for a given feature, text label wouldn't be drawn if the stylization rule used, place it outside of map request boundary. Riccardo Il 30/07/2013 03:26, Jackie Ng ha scritto: Yes, I'm asking a question here :) Does anyone know if Advanced Stylization lifts the limitation of label display on line/area styles being at the mercy of the renderer? ie. Does Advanced Stylization have anything akin to (fixed labels for basic point styles) for line/area styles using Advanced Stylization? - Jackie -- View this message in context: http://osgeo-org.1560.x6.nabble.com/Advanced-Stylization-labelling-tp5069517.html Sent from the MapGuide Users mailing list archive at Nabble.com. ___ mapguide-users mailing list mapguide-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapguide-users ___ mapguide-users mailing list mapguide-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapguide-users
Re: [mapguide-users] Dinamic Tile Render
Ok, I'm not talking about tiling as a cache system, I know that in webgis this is the common meaning of the word, so I will not use it anymore :) I have a customer that asked me to implement a service that generate in background (during night) pdf file for later print. To do that I have encapsulated the image I retrieve via GETDYNAMICMAPOVERLAYIMAGE in pdf file. To obtain a decent result i have increased SETDISPLAYDPI parameter to 300 and adjusted SETDISPLAYWIDTH,SETDISPLAYHEIGHT and SETVIEWSCALE to produce the image I need. This work well till A3 print format. Then my customer ask me to generate A0 pdf file with the same quality. I explained him that it is not possible, since the image to retrieve it simply to big for MapGuide to generate. He pointed me out that A0 are just 8 A3 paper side by side, so what I'd should do is to make 8 independent request to GETDYNAMICMAPOVERLAYIMAGE and then make a collage inside PDF... The problem is that each request produce an image that is optimized for the specific view, so the combined image does not looks well at the border of two adjacent tile. A label for a polygonal feature, for example, could be render in both tile if the polygon is splitted a half in and a half in another tile. I know that this is how MapGuide work and there is nothing to do. I just wonder if in the future, could be technically possible to have a rendering option to tell MapGuide to stylize feature without optimization at the border of the view. I'm interested to this not much for printing purpose, but to develop mobile application. I'm sorry for my poor english :) Riccardo ___ mapguide-users mailing list mapguide-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapguide-users
Re: [mapguide-users] Dinamic Tile Render
Hi Hans, Thanks for the answer. I didn't tried yet to generate pdf with tiles. I gave up, due to rendering issue at the border of each tile when you deal with vector layer. Riccardo Il 15/04/2013 11:48, Hans Milling ha scritto: Hi Riccardo Do you put the individual pictures inside the PDF? I think that PDF files smooth the edges of images making them semi transparent. Perhaps the GDI+ fuctions is doing this (you can turn this off i think). What I do to produce A0 print is: 1. Make a bitmap that is the size of the output image. A0 600 dpi will be like 19000x26000 pixels. 2. Render the tiles and draw them in the bitmap (Using the Graphics object and DrawImageUnscaled). 3. Save the bitmap or put it inside a pdf. The A0 bitmap in memory is a little over 2 GB in size and when saved as PNG is 1.2 Gb in size on my machine (when printing ECW/Orthofoto). I guess vector maps will be less once compresed. I am not sure if anyone want to print A0 images or have any printer or software that can handle images of this size.

Re: [mapguide-users] Dinamic Tile Render
Jackie, I like your solution, not for printing but for mobile apps it could work (at least with device with normal pixel density...) Do you think the new Map Definition with base layer, could be stored in session repository? I ask it because see that tiles are stored in the filesystem, in folder named path_to_mapdefiniton_mapname.

Re: [mapguide-users] Dinamic Tile Render
Hi Jackie, That's true, But I think about some use case where dynamic tiles could be very useful: 1) Large format, high definition print service: if you want to create e pdf file of your map in A0 format and 1200 dpi resolution ( ! ), it could be possible to make a collage of tiles. 2) Mobile mapping application: during last few days, I've played with Google Maps Android Api v2. There is a TileProvider service you can implement to overlay map image generated with MapGuide. Obviously, at the tiles border, label and linestyle does not match very well, but it's amazing to rotate an tilt your map... and you can store the tiles on the device for offline navigation! Since MapGuide can generate tiles for base layers, could be feasible to extend such behavior to dynamic layers? Actually this is my n°1 position on mapguide wishlist! Riccardo Il 12/04/2013 08:16, Jackie Ng ha scritto: Dynamic tile is an oxymoron. Tiles are renderings of base layers at fixed zoom levels from a discrete list of finite display scales.

[mapguide-users] Selection image opacity in Fusion
Hi all, Is it possible to change opacity value of selection image in Fusion? I tried setting low alpha in SelectionColor element within my .ApplicationDefinition file but it seems that alpha component is ignored. thanks Riccardo ___ mapguide-users mailing list mapguide-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapguide-users
Re: [mapguide-users] no MapGuideJavaApi in java.library.path
I think that problem is in the name: in Linux system, JNI search for something named libMapGuideJavaApi.so, and that file should be found in the library path, while in windows system it search for MapGuideJavaApi.dll. You may try to make a symbolic link to the object created by build system named libMapGuideJavaApi.so The easiest way to put a library in the library path is to ensure that the directory where is located is in the system path. Hope this helps Riccardo gimbrogno @smartlab ha scritto: Hi, I have installed Mapguide OpenSource on same linux systems (ubuntu 7.10 and CentOS 5.1), but I have an error zwhen try the java sample !!!
