[worldKit-dev] Image layers and transperancy

[Mikel Maron]

Hi Matt

This is straightforward to code. Make worldkitConfig aware of a new attribute on swflayer, and then set the transparency of the layer in worldkitImages. Let me know if you need any specific pointers.

Subject: [worldKit-dev] Image layers and transperancy

Hi

 

In Worldkit I am using a layer (which is a map of the propergation pattern of a two way radio) to overlay a map of the city.

 

<swflayer id='syd07' width='1200' height='1215' extent='150,-35,152,-33' category='radio'>/maps/topomaps/syd07L.gif</swflayer>

 

The image used for the layer is a gif with transparent "holes" in it.  So I can see the map underneath through the wholes.

 

I would like the to make the layer semi-transperant all over so that I can see that map through the propergation pattern.

 

I guess what I am after is something like <fillalpha> but for an image layer 

 

It would be really nice if the user could change the alpha levels them whilst viewing.

 

Any ideas ??

 

Matt  :)
