I'm trying to put fractionalzoom in place but I'm going round in circles. It seems that you can only use fractionalzoom on a non tiled map server, but the Drupal Openlayers module seem to allow only tiled map servers to be base layers...

Am I missing something?

Yeah... it's true, there's no current support for fractional-zoomed layers. I assume you have a WMS server that you're set to work with? From how the OpenLayers.org example works, it looks like this could be implemented either as a setting on presets or as a behavior, but it would need a lot of scare documentation to prevent people from expecting this to work with anything besides WMS.

Yes I have a Mapnik server, but I can't seem to be able to set a WMS layer as a base layer, is this an openlayer restriction or my server that is not well configured?

(thanks for the quick reply and the wonderful module).

Hi @jun, what do you mean by "can't seem to be able to set a WMS layer as a base layer"?

* You don't see the Base Layer option on the layer form or
* it is not showing up as a Base Layer in the preset form, or
* it does not show up as a Base Layer on the actual map or
* something else?

For the base layer issue, this should be fixed in 2.x-dev: #862690: Layer marked as 'base layer' does show up in preset as 'overlay'

Otherwise, changing ticket to feature request.
Reference: http://dev.openlayers.org/releases/OpenLayers-2.9.1/examples/fractional-...

Also note, that this seems to be a map level option.

Patches accepted; otherwise, fractional zoom layers are so few and far between, and require so much support for near-dead-end things like single-tile WMS layers, that it doesn't make sense for maintainers to invest time here.
