IE 9 mosaic dataset discolor colormap

gisscconsulting — Tue, 25 Oct 2011 02:44:11 GMT

I have a mosaic dataset (hundards of rasters with colormap built in) published as image service.

After imageServiceLayer.setOpacity(0.4);
I also set mosaic rule to show 1 image at a time

The color of the image seemed faded and discolored in IE 9 when I pan and zoom. In FireFox the color retains.

IE seems can not get image ransparency right?

After chat with ESRI analyst, the solution is to use setOpacity before addLayer event.

imageServiceLayer.setOpacity(0.4);
map.addLayer(imageServiceLayer);

If is setOpacity is used after addLayer event, IE tends to have problems.

dojo.connect(imageServiceLayer, "onLayerAdd",function()){
imageServiceLayer.setOpacity(0.4);
}
