[ka-Map-users] PNG24 Transparency in IE

[Delfos, Jacob]

Shoab,
 
As an alternative, you can use GIF for your transparent layers, which comes out smaller than 8 or 24bit PNG. You can then use JPEG for your 24bit layers (providing you don't need your 24bit layers to be transparent). Using the "imageformat" parameter in the metadata, you can force these image formats on an individual layer basis.
 
regards,
 
Jacob

		1) How did you configure your mapfile to have transparency on Firefox? 
		All my layers appears opaque on FireFox.


	In my mapfile I set
	IMAGETYPE png24
	 
	and config.php
	  "deakinPNG24" => array( "Deakin Marine Map (PNG24)", "/opt/Mapfiles/deakinbathy.map",
	                     array( 300000, 100000, 30000, 20000, 10000, 5000, 2000 ),
	                      "PNG24"),
	
	That's about it.... 
	
	

		2) Can I fix this problem with IE and PNG24, changing the format file to
		JPEG?


	I tried that but jpeg didn't help
	still scratching my head about 24 bit images and transparancy in IE :(
	


		Thk 4 all.
