OK - here is what works:
Once I have read in the local GPX file into memory, I have a function that
creates the Vector layer:
var gpx_format = new OpenLayers.Format.GPX({externalProjection: new
OpenLayers.Projection('EPSG:4326'),
internalProjection: new OpenLayers.Projection('EPSG:2193')});
var reader = new FileReader();
reader.onload = function(event) {
var contents = event.target.result;
//alert(contents);
var olgpx = gpx_format.read(contents);
var gpxl = new OpenLayers.Layer.Vector("GPX Points",
{isBaseLayer: false,
styleMap: gpxStyles,
rendererOptions: {zIndexing: true},
extractAttributes: true });
gpxl.addFeatures(olgpx);
alert("added " + gpxl.features.length + " features to layer");
map.addLayer(gpxl);
alert("added gpx layer to map");
map.zoomToExtent(gpxl.getDataExtent());
};
Kind regards,
Robert Sanson
