[OpenLayers-Users] OpenLayers.Layer.Image overlay?

[Erik Uzureau]

Hi Rob,

Try this?


navmap = new OpenLayers.Layer.Image( 'Nav', 'http://waage.sr.unh.edu/
data/13283_1.png',
               new OpenLayers.Bounds(-70.7700123,42.9445234,-70.5597821,
43.1740090),
               new OpenLayers.Size(8563, 12740),
               {'maxResolution': 'auto', 'isBaseLayer': false }
);

to get it to be an overlay. as for the image quality... not sure how to help
you with that.

Erik
