[OpenLayers-Users] display an image file in openlayers

[Massimo Di Stefano]

Hi All,


I'm tring to display an image file in open layers .. but i'm not able to do it

i'm starting from the image layer example .. so what i did is :

reproject my geotiff file to lonlat (epsg 4326)
extract the geographic information using gdalinfo :


Size is 2615, 2812
Coordinate System is:
GEOGCS["WGS 84",
    DATUM["WGS_1984",
        SPHEROID["WGS 84",6378137,298.257223563,
            AUTHORITY["EPSG","7030"]],
        AUTHORITY["EPSG","6326"]],
    PRIMEM["Greenwich",0],
    UNIT["degree",0.0174532925199433],
    AUTHORITY["EPSG","4326"]]
Origin = (10.761638708120071,59.081962786832037)
Pixel Size = (0.000160206206100,-0.000160206206100)
Metadata:
  AREA_OR_POINT=Area
Image Structure Metadata:
  INTERLEAVE=BAND
Corner Coordinates:
Upper Left  (  10.7616387,  59.0819628) ( 10d45'41.90"E, 59d 4'55.07"N)
Lower Left  (  10.7616387,  58.6314629) ( 10d45'41.90"E, 58d37'53.27"N)
Upper Right (  11.1805779,  59.0819628) ( 11d10'50.08"E, 59d 4'55.07"N)
Lower Right (  11.1805779,  58.6314629) ( 11d10'50.08"E, 58d37'53.27"N)
Center      (  10.9711083,  58.8567129) ( 10d58'15.99"E, 58d51'24.17"N)
Band 1 Block=2615x1 Type=Float32, ColorInterp=Gray


then i used gimp to convert the file to .gif

and i used this lines to add the layer in the open layers :



            var graphic = new OpenLayers.Layer.Image(
                'Depth',
                'depthgeo.gif',
                new OpenLayers.Bounds(10.7616387080555551, 58.6314629352787620, 11.1805779369442959, 59.0819627869444446),
                new OpenLayers.Size(2615, 2812),
                options
            );



 the results is an empty html page .. open layer is not loaded at all :(

the gif image is available here :
