[OpenLayers-Users] Min Zoom Level

[Matthias Woltering]

Hi Warren,

you can set set the scales manually like this:

var options = {
  maxExtent: new OpenLayers.Bounds(1430000,4400000,1760000,4660000)
  ,maxResolution: "auto"
  ,scales: [1000000,500000,250000,100000,50000,25000,10000]
  ,units: 'm'
  ,projection: 'EPSG:31466'
  ,controls: []
  //,zoom: 1
  //,numZoomLevels: 8
};
map = new OpenLayers.Map('map', options);

If you don't want to set scales use numZoomLevels.

Regards,
Matthias
