Hello All,
I have some problem with re positioning of icons on different layers.
I have added 2 layers and 3 icon layers to the main base layer.
after performing zoom in and zoom out operation for nearly 2 to 3 times. the
icons are changing it's position. once i refresh, the icons would be in a

the variable holding the layer).
Could anyone point me in the
Not really an OpenLayers question but I think you need to use:
clone.get(layer).setName(pmpm);

Hi,
I would advise you to look at OpenLayers.Layer.ArcIMS which uses a similar
approach.

Hi Bart,
thanks for the fast and helpful response!
One question though: which class actually invokes the methods
OpenLayers.Layer.ArcIMS.getUrl and OpenLayers.Layer.getUrlAsync?
They seem to be overriden methods, but i couldn't find them in
OpenLayers.Layer.Grid or OpenLayers.Layer.HTTPRequest.
Hi Franz,
check out OpenLayers.Tile.Image.

Hi Bart,
I'm almost done with my layer implementation. The only problem: my
getURLasync() Method gets triggered far too often (about 3x per pan/zoom
action).
How can I make sure that getURLasync is only triggered once per map action?

Hi Alex,
'clickTolerance' is a OpenLayers.Handler.Feature property. If you
look in the Select.js file, you'll see that the handler is set inside
the initialize method and that there is no way other than modifying the
code there to set your own 'clickTolerance'. A thing you could do is to
Hi Franz,
and have you verified you only have a single tile?
Do you have singleTile: true, ratio: 1 and buffer: 0 in your layer options?

yes, I've set these options. I noticed that these multiple requests only
happen when I set transitionEffect: 'resize'.
I'm using OpenLayers 2.9.1.

Hi Group
Is it possible to prevent OL fetching the map until you release your mouse
from panning. Because I don't want it to be fetching maps, until the panning
is done. Yes I know it seems a bit ackward, but it for a mobile app where
the bandwidth is not fast, so therefor I need this.

You may want to listen to featureadded or featuresadded events instead.

This is basically expected. The transition effect creates multiple tiles, and

Hi,
this is not currently supported for tiled layers, but if the layers in question
are WMS, you can set the singleTile option of the WMS layers to true (and ratio
to 1). This will result in fetching a map for the visible extent when the mouse
is released.

Andreas.

Andreas, that was the one, thx.

In my case, creating the single-tiled map is rather expensive - because the
map image is generated on-the-fly.
Therefore, I want my layer to anticipate the map action (zoom, pan), just
like the ImageLayer does.
I actually had a well working implementation of my map viewer based on

I encountered a strange behavior I don't understand: Sometimes I want to cover
my whole world map with a dark layer except a distinct region. This is meant to
emphasize a certain region of the world. My approach is creating a polygon

Hi,
does the feature also disappear in Internet Explorer? If not, and if you are
not interested in support for older versions of Firefox, Safari and Opera, you
could set
OpenLayers.Renderer.SVG.prototype.MAX_PIXEL = Number.MAX_VALUE;
before creating your map.

Andreas.

Hi Andreas,
thank you for your answer. Unfortunately it didn't work either in IE. Do you
know what mechanism is responsible to remove the feature from the map, maybe
there is a way to prevent it. If there is no way to achieve this I will have to
search another way to stress this region...
I have added the on load and it seem not to be affecting other features now
but I still get a smudge for a fount.

Hello Group,
Is it possible to have a single map tile ( WMS and/or other map services )
in OpenLayers ?? I want to have a single tile for the whole bounds I set for
the map. Also, when I zoom in , out or pan the map should generate single
tile but not multiple tiles.
Any one has any ideas ??
