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
