Hello,
I got same need as you, to display Zoomify-Tiles on top of an OSM base
layer. Did you find any solution ?
For simple image file I could get it pretty simply :
var extent = ol.proj.fromLonLat(e.zone.startCoord).concat(
ol.proj.fromLonLat(e.zone.endCoord));
var source = new ol.source.ImageStatic({
url : url,
imageSize : [img_width, img_height],
imageExtent: extent
});
var imageLayer = new ol.layer.Image({
source : source
});
var osmLayer = new ol.layer.Tile({
source: new ol.source.OSM()
});
var view = new ol.View({
projection: projection,
center : ol.extent.getCenter(extent)
});
var map = new ol.Map({
layers : [osmLayer, imageLayer],
target : 'map',
view : view
});
map.getView().fit(extent, map.getSize());
But for Zoomify-Tiles I can't get to any solution. I think I will have to
convert my image into georeferenced XYZ-Tiles.
