Displaying a theme-based FOI layer as a whole image with javascript API v2

Hi,
I have looked the Oracle maps V2 tutorial developed in mvdemo.war application provided with Oracle Mapviewer v11.1.1.7. I have looked how to use theme-based FOI layers and I have not found how to set the "whole image" property for these layers. This feature is present in javascript API V1 and it greatly improves application performance. Our applications use this property very often.
Is this property present in javascript API V2 but not documented?
If it's not present, do you know if it will be?
How can we show a layer with many geometry features and obtain the same performance we have now with the whole image property?
Thanks,
Arturo

Hi,
since this is a very crucial feature for us I'm very interested in that functionality as well. Is there a comparable functionality in the V2 API or will it be available in feature releases?
Thanks
Dominik

Templated Theme Based FOI layer Error

I'm trying to add FOI like in an example - Templated Theme Based FOI layer.
Javascript:
var tbfc = 0;
function addMyFOI(oKOD){
tbfc++;
var foi_name = 'foi'+tbfc;
var tbg = new MVThemeBasedFOI(foi_name,'cad.dj');
tbg.setQueryParameters("'"+oKOD+"'");
tbg.setBringToTopOnMouseOver(true);
mapview.addThemeBasedFOI(tbg);
dynamic theme:
<?xml version="1.0" standalone="yes"?>
<styling_rules>
<hidden_info>
<field column="NOMER" name="ffff"/>
<field column="DOM" name="ffff"/>
<field column="LIT" name="dff"/>
</hidden_info>
<rule>
<features style="M.CYAN PIN"> (NOMER=:1) </features>
</rule>
</styling_rules>
When i call addMyFOI function i get error looks like this:
06/10/20 01:06:10 ERROR [oracle.lbs.foi.FOIServlet] [Foi Server] foi width value is wrong.
Does anybody know what it is?

var mapZoom = 5;
var mpoint = MVSdoGeometry.createPoint(mapCenterLon,mapCenterLat,262148);
mapview = new MVMapView(document.getElementById("map"), baseURL);
mapview.addBaseMapLayer(new MVBaseMap("CAD.TYUMEN"));
mapview.setCenter(mpoint);

ovcontainer.setCollapsible(true);
mapview.addMapDecoration(ovcontainer);
var over=new MVOverviewMap(ovcontainer.getContainerDiv(),3);
mapview.addOverviewMap(over);
mapview.display();
I use this code to initialize my map.
Hmmm, I still cannot solve that problem

How refresh(redraw) one element in dynamic (JDBC) theme-based FOI layer?

MapViewer version: Ver11_B090501
I'm add layer on map:
var QFM = createQuery('formosat', ordsArray.toString(), begd, endd);
var TFM = createTheme(QFM);
var HTFM = new MVThemeBasedFOI('HTFM', TFM);
HTFM.setRenderingStyle("C.FM");
HTFM.enableHighlight(true);
     HTFM.setHighlightStyle("C.SP");
     HTFM.setHighlightMode("multiple");
     HTFM.setMaxWholeImageLevel(maxImgLev); // 7
     //HTFM.enableImageCaching(true);
mapview.addThemeBasedFOI(HTFM);// add on map
If i try click on FOI element, it will be not Highlighted (because im used setMaxWholeImageLevel(maxImgLev); // 7). Can i redraw only selected elemet?

Feature highlighting only works when the theme is NOT displayed as a whole image.

You must use ROWID
function createTheme(q,s){
var t = "<themes><theme name='MY_JDBC_THEME' >" +
"<jdbc_query asis='true' key_column='*rowid*' spatial_column='geom' jdbc_srid='40998' " +
"render_style='"+s+"' datasource='sovzond'>" +
q +
"</jdbc_query>" +
"</theme></themes>";
return t;
}

Displaying default styles in an advanced style as theme based foi

Hi,
I have a problem to display the default style of an advanced style as theme based foi.
According to the mapviewer log x feature were found to display but no one was rendered into the map.
MapViewer with image layer works, MapBuilder, too.
MapViewer version:
Ver1033p5_B081010
MapBuilder marker definition:
<?xml version="1.0" ?>
<AdvancedStyle>
<BucketStyle>
<Buckets default_style="C.ORANGE">
<CollectionBucket seq="0" type="string" style="C.BLUE">90002,19208</CollectionBucket>
<CollectionBucket seq="1" type="string" style="C.RED">14002,13004</CollectionBucket>
</Buckets>
</BucketStyle>
</AdvancedStyle>
The mapviewer log indicates 7 found featuers, but only 2 of them are displayed. The 5 items are using the default style and are not visible.

Hi Joao,
thanks!
Do you know a workaround or alternative for that problem?
I have a request of our customer. He has about 400 different group items. Only a few of them (40-60) should be defined with an individual style and the rest with a default style.
The problem is, that the number of group items rises nearly daily. The new ones should automatically be displayed with the default style.

Overlapped theme based FOIs in FireFox

Hi. Ive got problem with using overlapped theme based foi's in firefox. The problem is that only one foi is clickable, and the foi under the upper one is only displayed but not active. It works in IE. One foi is polyline and other is polygon. Is there any solution ?

I've got the same issue.
Have you managed to deal with this somehow?

[HELP] Error: "JDBC theme based FOI support is disabled for the given data"

Hi all,
I have already set up MapViewer version 10.1.3.3 on BISE1 10g OC4J server. I am current using JDK 1.6. I create a mvdemo/mvdemo user for demo data.
The MapViewer demo is running fine with some demo without CHART. But give this error with some maps that have CHART like: "Dynamic theme, BI data and Pie chart style", "Dynamic theme and dynamic Bar chart style". The error is:
----------ERROR------------
Cannot process the FOI response from MapViewer server. Server message is: <?xml version=\"1.0\" encoding=\"UTF-8\" ?> <oms_error> MAPVIEWER-06009: Error processing an FOI request.\nRoot cause:FOIServlet:MAPVIEWER-06016: JDBC theme based FOI support is disabled for the given data source. [mvdemo]</oms_error>.
----------END ERROR------
I searched many threads on this forum, some point me to have this allow_jdbc_theme_based_foi="true" in mapViewerConfig.xml and restart MapViewer.

I have this configuration, but no luck. Could anyone show me how to resolve this problem?
Rgds,
Dung Nguyen

Oop, i managed to have this prob resolved!
My prob may come from this I use both scott and mvdemo schema for keeping demo data (import demo data).
Steps i made to resolve my prob are:
1) Undeploy MapViewer from Application Server Control (http://localhost:9704/em in my case)
2) Drop user mvdemo
3) Download mapviewer kit from Oracle Fusion Middleware MapViewer & Map Builder Version 11.1.1.2
4) Deploy MapViewer again
5) Recreate mvdemo and import demo data
6) Run mcsdefinition.sql, mvdemo.sql with mvdemo user (granted dba already)
7) Edit mapViewerConfig.xml
<map_data_source name="mvdemo"
jdbc_host="dungnguyen-pc"
jdbc_sid="bise1db"
jdbc_port="1521"
jdbc_user="mvdemo"
jdbc_password="!mvdemo"
jdbc_mode="thin"
number_of_mappers="3"
allow_jdbc_theme_based_foi="true"
/>
Save & Restart MapViewer
And now, all demos run fine. Hope this helpful for who meet prob like my case.

Problem refreshing theme based FOI

Hi,
We have a map and we want to display shops on it. That works, however new new call containing a different collection of shop IDs does not result in a refresh of the map in the sense that these new shops appear on it. I have been studying the JavaScript API, and I thought that I did find the (best) way to do this, namely the following flow (omitting less relevant code):
1. First we start with a function that initializes the MapViewer object:
function showRasterMap(){
raster_mvo = new MVMapView(document.getElementById("rastermap"), baseURL);
var base_map = new MVBaseMap("MVDS.RASTER_MAPCACHE");
base_map.setVisible(true);
raster_mvo.addBaseMapLayer(base_map);
raster_mvo.setCenter(MVSdoGeometry.createPoint(center_x, center_y, 90112));
raster_mvo.setZoomLevel(0);
raster_mvo.addScaleBar();
raster_mvo.display();
2. Then when the end user clicks on a node of a tree widget, a second function is called that collects the shop IDs and passes that array to a function that sets the query parameter.
function RasterWindow_loadRasterKaart(){
var data = dojo.json.serialize({nodeId: list.activeNodeId});
request = {data: data, action: "getBaseIds"};
     dojo.io.bind({
     url: "list.do",
     load: rasterWindow.bolletjesCallback,
     mimetype: "text/plain",
     content: request,
     preventCache: true
function RasterWindow_bolletjesCallback(type, data, evt){
var arr = dojo.json.evalJson(data);
prepareArraydMap(arr);
3. Now the interesting part comes, namely the question how to (best) refresh the map. I solved like this: when the ThemeBasedFOI doesn't exist yet, then it will be initialized and added to the MapView object. But when it already exists, then it needs to bind the new query parameter, execute the query and refresh the MapView object. The reason for proceeding like this, is of course to avoid to re-create the ThemeBasedFOI and MapView objects again and again (which doesn't look like a good coding practise and intuitively looks less performing). So my little function became something like this:
function prepareArraydMap(arr){
var myArrayParam = new ArrayParameter(arr,'narray','t_unitids')
if (raster_foi == null) {
raster_foi = new MVThemeBasedFOI('rasterUnitsFoi','MVDS.THEMERASTERUNITS', baseURL);
raster_foi.setQueryParameters(myArrayParam);
raster_foi.setBringToTopOnMouseOver(true);
raster_foi.addEventListener("mouse_right_click", foiRightClick);
raster_foi.enableInfoTip(true);
raster_foi.setVisible(true);
raster_mvo.addThemeBasedFOI(raster_foi);
else {
     raster_foi.setQueryParameters(myArrayParam);
     raster_foi.setVisible(true);
     raster_foi.refresh(false);
raster_mvo.display();
The problem is however, it does not work. The first request to display the shops on the map is: request=getfoi&version=1.0&theme=MVDS.THEMERASTERUNITS&bbox=-265933.3333333333:29066.666666666686:546866.6666666666:841866.6666666666&width=1536&height=1536&paramnum=1&param1=257476,118262&paramtype1=narray&sqltype1=t_unitids&area=yes&dstsrid=90112
Subsequent requests (for different shops) have a likewise request, but do not result in shops being displayed (only the map is visible). Also: a strange post appeared (in FireBug), namely: POST http://localhost:8888/mapviewer/ReturnLocaleOper, which contains:
i0=Pan%20NorthWest&i1=Pan%20North&_i2=Pan%20NorthEast&_i3=Pan%20West&_i4=Pan%20East&_i5=Pan%20SouthWest&_i6=Pan%20South&_i7=Pan%20SouthEast&_i8=Slider%20Bar&_i9=Drag%20To%20Zoom&_i10=Zoom%20In&_i11=Zoom%20Out&_i12=Scale%20at%20the%20center%20of%20the%20map&_i13=MapView%20baseURL%20is%20not%20set,%20please%20check&_i14=km&_i15=mi&_i16=m&_i17=ft&_i18=Home

I am lost. I would very much appreciate any help.
Greetings, Erik

I have separated the map code from the main application, and it works now: I can display FOIs and display another set of FOIs by calling the refresh method of the MVThemeBasedFOI. The JavaScript code is quite simple:
function showRasterMap() {
raster_mvo = new MVMapView(document.getElementById("rastermap"), baseURL);
raster_mvo.addBaseMapLayer(new MVBaseMap("MVDS.RASTER_MAPCACHE"));
raster_mvo.setCenter(MVSdoGeometry.createPoint(150000, 450000, 90112));
raster_mvo.setZoomLevel(0);
raster_mvo.addScaleBar();
raster_mvo.display();
function showRasterFOI(arr) {
var t0 = new Date();
var arrParam = new ArrayParameter(arr, 'narray', 't_unitids');
if (raster_foi == null) {
raster_foi = new MVThemeBasedFOI('rasterUnitsFoi', 'MVDS.THEMERASTERUNITS', baseURL);
raster_foi.setQueryParameters(arrParam);
//raster_foi.setBringToTopOnMouseOver(true);
raster_foi.enableInfoTip(true);
raster_foi.setVisible(true);
raster_mvo.addThemeBasedFOI(raster_foi);
else {
raster_foi.addEventListener('after_refresh', function() {
var t1 = new Date();
var diff = t1 - t0;
alert('timer: ' + diff + ' msec');
raster_foi.setQueryParameters(arrParam);
raster_foi.refresh(true);
//TODO: check if zooming is required
//raster_mvo.display(); THIS KILLS PERFORMANCE
So everything looks fine here, except the performance, namely in my browser it takes 33 seconds to display a single FOI !
However I had a look on the code again, and I found that the last call to display the MVMapView object resulted into the gigantic perfomance breakdown as mentioned above. When reading the API, I didn't get consious of this performance penalty. The API just says about the display method: "This method displays all map content inside the map container (which is an HTML DIV element defined in the web page)."
Maybe you could find time to extend the API with information and advices of how to best use it, especially witn respect to performance.
I am happy that I managed to solve this issue that turned our hear into grey color.

How to flip a layer without flipping whole image?

How do I flip a layer (horizontally or vertically) without flipping the whole image?

Theme based FOI

Is it possible to get the theme name from a FOI when it is clicked.
I am adding a number of themebased layers to my map.
Each layer has a mouse click event listener so that can use displayInfoWindow and show more details about the FOI from the database.
in order to do this I need to get the layer the FOI belongs to so that I can create the correct query.
Thanks in advance
Ian.

Do all the themes share the same click event listener function?
1) If they don't, then you know which listener function is attached to which theme. As shown below, it's easy to add code in the listener function to tell which theme it belongs to.
theme1.attachEventListener(MVEvent.MOUSE_CLICK, listener1) ;
theme2.attachEventListener(MVEvent.MOUSE_CLICK, listener2) ;
function listener1(...)
var theme = "theme1" ;
function listener1(...)
var theme = "theme2" ;
2) If the themes share the same listener function, then for every theme, you can create a new listener function that invokes the original listener function. As the result, the themes no longer share the same listener and we're talking about scenario 1) again.

UNABLE TO CLCIK ON 1ST FOI LAYER WHEN ANOTHER LAYER IS DISPLAYED

Hi Team !
Using Mapviewer Javascript API to add layers to a map, with set visible = false.
when 1 layer is made visible, the point item can be clicked on/selected. Make another layer visible and the 1st layer becomes deactivated.
Is it expected behavior ?
Thank you,
Raj

I have 2 theme based FOI layers.The 2nd layer covers the 1st layer. I need process an event "mouse_click" on 2nd layer.But 2nd layer doesn't get this event, the 1st layer gets. How may I propogate these event from 1st layer to 2nd layer? I tried to use a function enableEventPropagation() on 1st layer but it didn't help.

Displaying themes based on Zoom levels in base map

I am using Oracle AS MapViewer 10131.I have 3 themes added to a base map.
I am using Oracle Mapbuilder to create Mapping metadata.I want to display the 3rd theme based on the zoom levels.I want to display it only at lower zoom levels.I have followed necessary instructions given in the Mapviwer user guide and mapbuilder help.
But I am not able to display particular theme based on Zoom levels.
For example I have min/max scale 70,000/0 for Streets theme set using mapbuilder.This theme should be displayed only at that scale.But I am getting this theme displayed at all min/max scales (zoom levels).While creating the Map Cache Instance given the min/max scales 1000/25000000, the default values.Here the scale values look contradictory to the theme scale values given in mapbuilder.Is this where I am going wrong? or while setting scale for themes?
I hope you understand my problem.Please help me about this.this is urgent.
Thanks in advance!!

My problem is solved now.I am able to display themes on zoom levels.The solution is, I set the min/max scale (zoom levels) in Map Cache Instance as "Ratio" and in theme i set it to "Screen-Inch".The scale of theme is not understood by the map cache instance.So finally i set both the scales to "Ratio" and it is working fine as i expected.
Anyway thanks for yout interest in helping me.I will surely make a post here if i got stuck in further work.

IPad retina via iOS simulator can not display the whole image (2048x1536)

Hi,
I am developing cartoon ebooks with iOS simulatort 7.0. The target device is iPad retina. I use the image whose size is 2048x1356. After building by iOS simulator--iPad retina, only center part of image was displayed. I hope to show the whole image with simulator, how should I do?
Thanks!

You would do better to ask your question on the developers' forum. We are but simple users here....

Display of PS files w/layer masks in Aperture

I frequently use the "open in external editor" command to edit images in PS. Mostly, this works very well and I'm able to view the edited image in Aperture without a problem. However, for some images with layer masks created in PS, when I save them and return to Aperture only the layer mask is visible (not the image as it should appear). Has anyone else had this problem? Is it a bug, or intentional? Any way around it?
Thanks,
Chris

Hi,
I've seen this too. I think it is the bug related to displaying PS-files in 10.4.6
see: http://www.completedigitalphotography.com/?p=422#more-422
We can just hope 10.4.7 deals with it.
cheers,
