MapServer Transparent PNG Layers

Reply Threaded

I'm attempting to user multiple MapServer maps using transparent PNGs so
that the end-user perception is that things load much faster. I'm
running into two problems:

1.) The 4 defined maps are not stacking correctly, getting my last map
(points.map) underneath one of the others (us_streets.map). But what is
interesting is that this behavior is not consistent, sometimes they are
in the right order but sometimes they are not.

<MapGroup id="mapserver" xsi:type="MapType">

2.) When I try the above map setup the Legend sort of breaks. I have to
set ShowMapFolder to 'true' in order to even get something more then
just the first group of the base layer to show up in the Legend. Also
most of the individual layers with their legend symbols show up, with
the exception of the few layers that I have condition CLASSes on. I'm
attaching 2 screen shots as examples. Does anyone have any ideas how to
fix this?

I'm not sure on how to fix the overlay map order issue but I was able to correct the legend issue with the maps that I am working with by changing the Legend.js widget source. Here are my changes:

renderLegend: function(r) {
this.bIsDrawn = false;
this.clear();

if (this.showRootFolder) {
this.oRoot.itemLabelobj.innerHTML = this.getMap().getMapTitle();
}

if (this.showMapFolder) {
this.renderGroup(this.layerRoot);
} else {
for (var i = 0; i < this.layerRoot.groups.length; i++)
this.renderGroup(this.layerRoot.groups[i]);
}

this.bIsDrawn = true;
this.update();
},

renderGroup: function(group) {
if (!group.legend) {
group.legend = {};
group.legend.treeItem = this.oRoot;
}
for (var i = 0; i < group.groups.length; i++) {
this.processMapGroup(group.groups[i], this.oRoot);
}
for (var i = 0; i < group.layers.length; i++) {
this.processMapLayer(group.layers[i], this.oRoot);
}
}

It might not be correctly done since I am fairly new to fusion, but it gets the job done. Hope it helps :).

MapServer Legend Icons

Reply Threaded

In reply to this post by Nolte, Tim

Last week I had posted about a problem with my legend icons not showing
up. I have multiple MapServer mapfiles defined. I'm not sure if the
problem I'm having is solely related to having multiple mapfiles or that
I recently updated to the latest Fusion trunk. I can say that the
problem with the legend icons is because of an error in
layers\MapServer\php\LoadScaleRanges.php, the section that it is having
a problem with is:

$oImg = $oClass->createLegendIcon($nIconWidth, $nIconHeight);

This is failing with the error:

Fatal error: Call to a member function createLegendIcon() on a
non-object

If I change the code to make sure that '$oClass' is not NULL then legend
icons do get created but they are not being created correctly. I'm not
sure if this is something where I need to use a different built-in
function to use one of the default Fusion layer icons? If anyone has any
ideas it would be a big help.

Hi Tim,

The legend icon stuff is working in another project that Paul
Deschamps is working on, he has multiple map files and a menu for
changing between them. The legend does appear to update correctly
when changing maps.

The way it *should* work is that LoadMap.php populates a session
variable 'scale_ranges' with an array of each scale range of each
class of each layer. LoadScaleRanges.php uses this array to get the
class for each scale range and draw the icon at the appropriate scale
for that class and then combines them all into a single image, and
returns a set of CSS offset values for use by the legend - so each
scale range has the same image source but different offsets.

I suspect what is going wrong is that the scale_ranges array is
somehow the wrong one. We need to know what sequence is causing
this. Is LoadScaleRanges being called before LoadMap finishes? Or
are you programmatically changing maps while loading them or between
loading and calling LoadScaleRanges?

Cheers

Paul

RE: MapServer Legend Icons

Reply Threaded

What I am seeing with Firebug is that there are 6 calls to LoadMap.php,
which are my 5 main maps and 1 overview map. After the 5th LoadMap.php
call then the LoadScaleRanges.php calls begin, there are 5 calls. One
thing that I noticed also is that the MapTips are not working and what
is being POSTed to the MapTip.php script is the wrong map for the layer
that I've selected for MapTips. Seems like there could be a problem with
using the SESSION if the LoadMap.php is not adding something to the
SESSION to directly link the call to the LoadScaleRanges.php so that
it's not pulling the wrong scale_ranges. Is there any debugging
information that I can send?

Ohhhhh - light goes on - doh! You have 6 maps in the same map group!
This will need a bit of work :) We need to modify the scale_ranges
array in the session so that it is subdivided by map name. LoadMap
needs to set

$_SESSION['scale_ranges'][$mapName]

and LoadScaleRanges needs to use the same thing when referencing it.
Do you think you could make these changes and test? If it works, I'll
file the bug and commit. If you don't want to try first, I can take a
stab at it and commit but I'm not really set up to test right now.

Thanks Tim

Paul,

I attempted this, however what I found was that the way the loading
process happens it is not enough to just stick the scale ranges into the
PHP $_SESSION. I'm finding that all of the individual maps in many cases
don't yet exist in the SESSION when the corresponding LoadScaleRanges is
called. Do you have any thoughts on how Fusion could be changed to only
call LoadScaleRanges 1 time after all of the LoadMap calls have
finished? I think this could be the fix. The only other option I see is
that the whole scale ranges creation process needs to be duplicated in
LoadScaleRanges script. I'm not sure but perhaps this functionality
needs to be added to the Utilities script?

Is this forum and/or project dead? How many people are actually using
this or developing for it?

Well, on a good note I finally got a somewhat working solution by
basically forgetting about trying to rely on $_SESSION and basically
copied a bunch of the LoadMap code that sets up the Scale Ranges over to
the LoadScaleRanges script. I also changed the script to also not rely
on the $_SESSION to tell it what mapfile it is supposed to use and
basically copied the code in LoadMap that sets up the SESSION based map.
There is still the issue of the Legend being sorted backwards, the
Legend icons not all updating properly when zooming in, as well as an
issue with the map layers not being stacked in the right order. I'm
plugging away at this. It would be really nice if no one else is really
working on MapServer specific development that I could start submitting
to the SVN or somehow my changes could get approved to be taken into the
project. I'll hate to have to use a diff utility every time there is an
update and have to fix my code so that things still work. Thanks to
anyone that is actually reading this, if there is anyone out there.

Hi Tim,

the project is not dead but I don't know how many folks are using it
right now. I know that MapGuide is actively using it and the Autodesk
team there is actively finding and fixing bugs related to the MapGuide

RE: MapServer Legend Icons

Reply Threaded

Paul,

Excellent! Thank you very much. I've making some good head way on the
whole Legend issue, especially when using multiple maps within a map
group. I'm going to switch over to a single map in the map group and see
what results I get also. I'm happy to be able to submit changes to the
MapServer side of the project. I hope that my work will help others that
are already using MapServer adopt Fusion as their framework of choice.

Hi Tim,

the project is not dead but I don't know how many folks are using it
right now. I know that MapGuide is actively using it and the Autodesk
team there is actively finding and fixing bugs related to the MapGuide
support. DM Solutions is also actively using and developing the
framework and the MapServer support.

I have added you as a committer, welcome aboard!

Hi Tim,

Welcome to the project. If your interested you can also download a live cd of MapGuide Open source. (http://mapguide.osgeo.org/node/127) and run it in vmware. If your interested. It's a nice way to see how fusion works with both platforms and it will help to make sure that when you fix an issue on one platform that it doesn't expose an issue on the other so it's a good idea to have setup anyhow.

Cheers
