Hi Steve
This is what I do:
include EPSG files specifically as required:
<script src='OpenLayers.js'></script>
<script src="lib/proj4js-combined.js"></script>
<script src="lib/EPSG2193.js"></script>
<script src="lib/EPSG27200.js"></script>
<script src="lib/EPSG4326.js"></script>
<script type="text/javascript">
Later, I have code that retrieves the entered coordinates and converts:
var src = new OpenLayers.Projection('EPSG:4326');
var dest = new OpenLayers.Projection('EPSG:2193');
latitude = document.getElementById('lat').value;
longitude = document.getElementById('llong').value;
var markergeom = new
OpenLayers.Geometry.Point(longitude,latitude);
//now in-place re-projection
OpenLayers.Projection.transform(markergeom, src, dest);
gpsx = markergeom.x;
gpsy = markergeom.y;
alert(gpsx + "," + gpsy);
Cheers,
Robert Sanson

I created a simple html page where the user enter lat/long coordinates and the
program returns the projected coord in EPSG 32198.
That works well, but if I insert the same code in a more complex program using
openlayers, the coordinates are not projected. Here is the code I put just
after map.setCenter()
var lon = -70.894826;
var lat = 48.329377;
var point = new OpenLayers.Geometry.Point(lon, lat);
var src = new OpenLayers.Projection('EPSG:4326');
OpenLayers.Projection.transform(point, src, map.getProjectionObject());
alert(point);
I included the script at the beginning of my program
<script src="../../proj4js/lib/proj4js-compressed.js"></script>
It seems that that the proj4js script is not found.
Any idea?
thanks
Steve
