Hi All, I am using a custom bitmap (878 x 823 pixel) as openlayer main background layer and I get the openlayers map display that I want (http://www.oifii.org/imt/dai/src/2010may31/index_CRCM_POLSTE-BITMAP.html).
I would like to be able to do coordinate (projection) transforms. Provided my bitmap is a stereo polar projection rotated in order to get north america vertical and center to canada, how could I modify my code here below (that works in pixel projection) to work with this specific projection? I need to do this because I want to overlay objects from a layer that I must query in lat lon (EPSG:4326). My code used to create the default layer is: minimumdefaultBounds=new OpenLayers.Bounds(0, 0, 1, 1); defaultBounds=new OpenLayers.Bounds(0, 0, 878, 823); var options= { minResolution: "auto", minExtent: minimumdefaultBounds, maxResolution: "auto", maxExtent: defaultBounds, //i.e. max bitmap size restrictedExtent: defaultBounds, //null to allow panning projection: myproj, controls: [new OpenLayers.Control.MouseDefaults(),new OpenLayers.Control.ArgParser(),new OpenLayers.Control.PanZoom()] }; map=new OpenLayers.Map('map',options); Regards, Stephane -------------------------------------------------------------------- Stephane Poirier, M.Sc.
