Hi,
I'm working on an application that requires that there be fractional
zoom capability for almost all layers.
I've been working with some XYZ layers with fractionalZoom (by setting
serverResolutions), however, I noticed that there are nasty white
grid-line artifacts that show up when on non integral zoom levels.
Upon reviewing what is going on, the artifacts are generated as a result
of scaling the layer <div>. I believe that this approach should be
changed to scale the tile images, rather than the layer div.
So, transformDiv() would have code in it like this:
transformDiv: function(scale) {
$(this.div).find('img').css('width',
function(i,v){ return v * scale; });
$(this.div).find('img').css('height',
function(i,v) { return v * scale; });
$(this.div).find('img').css('left',
function(i, v) { return v * scale; });
$(this.div).find('img').css('top',
function(i, v) { return v * scale; });
....
This appears to remove the tile artifacts.
Thanks.
