[OpenLayers-Users] maxResolution, minResolution and resolutions in OpenLayers

[Esben Taudorf]

Hi everybody.

 

 

In OpenLayers 2.9.1 my map options is defined with a maxResolution,
minResolution and a MaxExtent like below:

 

var mapOptions = 

{

    projection: 'EPSG:25832',

    units: 'm',

    maxExtent: new OpenLayers.Bounds(100000,6000000,1000000,6500000),

    minResolution: '0.125',

    maxResolution: '768',

    restrictedExtent: new
OpenLayers.Bounds(100000,6000000,1000000,6500000),

    controls: 

    [

    ]

};

 

This works fine in OpenLayers 2.9.1 but doesn't work with the nightly
build (version 19-07-2010 and 14-06-2010)

In the nightly build I get this error in firebug when adding the first
layer to the map:

this.resolutions is undefined: zoom = Math.max(0, Math.min(zoom,
this.resolutions.length - 1)); (Layer.js (line 1061))

 

 

When I define the resolutions in my map options like below the map works
fine again:

 

var mapOptions = 

{

    projection: 'EPSG:25832',

    units: 'm',

    maxExtent: new OpenLayers.Bounds(100000,6000000,1000000,6500000),

    minResolution: '0.125',

    maxResolution: '768',

    restrictedExtent: new
OpenLayers.Bounds(100000,6000000,1000000,6500000),

    resolutions: [768, 384, 192, 96, 48, 24, 12, 6, 3, 1.5, 0.75, 0.375,
0.185],

    controls: 

    [

    ]

};

 

I can see that there are some issues with the resolutions: 

http://trac.openlayers.org/ticket/2427

 

My question is now do I always need to add the resolutions in map
options or can I use maxResolution, minResolution and a MaxExtent?
