<DIV><FONT face=Arial size=2>Thanks for that info. I wasn't aware of it. You'd
have thought Microsoft would have fixed that up a while ago.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I guess I'll have to use gif to get transparency.
Would be good if the imagetype could be different for each layer, to be able to
keep 24bit colour. I might look into doing that. Worked well for me in
Chameleon.</FONT></DIV>

RE: [ka-Map-users] PNG transparency not supported in internet

<DIV> </DIV><FONT face=Arial size=2>
<DIV><BR>Hello Jacob,</DIV>
<DIV> </DIV>
<DIV>At the moment IE 5.5+ does not properly support PNG transparancy (IE7 beta
does, see <A
href="http://blogs.msdn.com/ie/archive/2005/07/29/445242.aspx">http://blogs.msdn.com/ie/archive/2005/07/29/445242.aspx</A>)</DIV>
<DIV> </DIV>
<DIV>However, there are some hacks to provide PNG transparancy for 24/32 bit
PNG's in IE 5.5+, some are listed at <A
href="http://blogs.msdn.com/ie/archive/2005/04/26/412263.aspx">http://blogs.msdn.com/ie/archive/2005/04/26/412263.aspx</A>.</DIV>
<DIV> </DIV>
<DIV>A good one is the hack at webfx <A
href="http://webfx.eae.net/dhtml/pngbehavior/pngbehavior.html">http://webfx.eae.net/dhtml/pngbehavior/pngbehavior.html</A></DIV>
<DIV> </DIV>
<DIV>Of course do not forget to question yourself if using hacks for this is
what you want. On the other hand if you want to support PNG transparancy for IE
this is a nice solution.</DIV>
<DIV> </DIV>
<DIV>Regards,</DIV>

[ka-Map-users] PNG transparency not supported in internet explorer</DIV>
<DIV> </DIV>
<DIV><BR>Hi all, </DIV>
<DIV> </DIV>
<DIV>Just figured out why Internet Explorer keeps coming up with a blank map,
but not sure how to fix it. It would appear that Internet Explorer does not
support the PNG transparency that mapserver outputs. So my transparent vector
layers come out perfectly white where there's no data. Firefox does support it,
though. In the screenshot you can see a normal tile and a transparent tile next
to one another. The tile comes out transparent in firefox, but not in internet
explorer. Has anyone else had this? And.... anything I can do about it?</DIV>
<DIV> </DIV>
<DIV>Not sure of this is in Bugzilla. Seems bugzilla for Ka-Map is down......
</DIV>
