Hi, We have a custom TMS layer over a basemap. The tiles are 32-bit PNG with alpha transparency channel. There is also an Opacity Slider widget in our OpenLayers app which dynamically changes the opacity of the layer.
It looks great on latest version of all browsers ...BUT for IE7 and IE8 we can see black edges around the features of the layer. Pretty sure this is a well documented <http://www.jacklmoore.com/notes/ie-transparency-problems> issue with older IE where it cannot handle transparency correctly - it fills alpha-transparency pixels with black. There seems to be a "fix" by using IE's filters (see link above):- But I'm not sure how we can use this to fix the black edges issue in our OpenLayers app. IE7 and IE8 are still widely used so we want our app to support them really. Any help or advice would be greatly appreciated.
