Hello all!
it seems to me there is a little inconsistence between the OpenLayers
stack order and the order of layers transmitted to the print module by
the PrintProvider.
In OL, layers are stacked using the layers' z-indices, not according
the map.layers order.
In the print() method of GeoExt.data.PrintProvider, layers are listed
in the print request using the following piece of code:
var pagesLayer = pages[0].feature.layer;
var encodedLayers = [];
Ext.each(map.layers, function(layer){
if(layer !== pagesLayer && layer.getVisibility() === true) {
var enc = this.encodeLayer(layer);
enc && encodedLayers.push(enc);
}
}, this);
jsonData.layers = encodedLayers;
=> layers are listed using the map.layers order.
Then in the generated PDF, layers are stacked in the same order, no
matter if a given layer should appear above the others because it has
a greater z-index in the OL map.
I'm wondering if it would not be more relevant to sort map.layers
according to the layers' z-indices before adding layers to the
encodedLayers list? Is it worth submitting a patch about that issue?
Thanks,
alex
