Hi, I am trying to use a Tiff image for display using openlayers. I tried to use the following code. This code resembles the one in the image-layer.htmlexample. The code is as follows:
<html xmlns="http://www.w3.org/1999/xhtml";> <head> <title>OpenLayers Image Layer Example</title> <link rel="stylesheet" href="../theme/default/style.css" type="text/css" /> <style type="text/css"> p { width: 512px; } #map { width: 512px; height: 512px; border: 1px solid gray; } </style> <script src="../lib/OpenLayers.js"></script> <script type="text/javascript"> var map; function init(){ map = new OpenLayers.Map('map'); var options = {numZoomLevels: 3}; var graphic = new OpenLayers.Layer.Image( 'City Lights', 'http://localhost/Aerial2005_1ft.tif', * new OpenLayers.Bounds(-117.065, -32.740, - 117.000, 32.782),* new OpenLayers.Size(5419, 4383), options); var jpl_wms = new OpenLayers.Layer.WMS( "NASA Global Mosaic", "http://t1.hypercube.telascience.org/cgi-bin/landsat7";, {layers: "landsat7"}, options); map.addLayers([graphic, jpl_wms]); map.addControl(new OpenLayers.Control.LayerSwitcher()); map.zoomToMaxExtent(); } </script> </head> <body onload="init()"> <h1 id="title">Image Layer Example</h1> <div id="tags"></div> <p id="shortdesc"> Demonstrate a single non-tiled image as a selectable base layer. </p> <div id="map"></div> <div id="docs"> <p> The "City Lights" layer above is created from a single web accessible image. If you construct it without any resolution related options, the layer will be given a single resolution based on the extent/size. Otherwise, it behaves much like a regular layer. This is primarily intended to be used in an overview map - where another layer type might not make a good overview. </p> </div> </body> </html> The bounding box values were taken by taking an estimate of the lat long values using google maps. The image is not bieng displayed. I have also taken the easting northing values of the image using ermapper software which are as follows: left bottom: 637283.68 E 1860785.83 N right top: 6312701.61 E 1865167.64 N I have not yet converted these values into latlong values but will do so once it is confirmed that I am headed in the right direction. Please help me out as to what should I do to get the image displayed. Following are the images shored in the htdocs folder. By the way, I am using Apache. Please help me out. Thanks, Arjun
