Quartz beta - transparent background color

Question

Quartz beta - will we be able to change the background color of the map view in iOS/Android? specifically, a transparent background color so that the underlying UIView is visible?

also, will the opengl context be available?

thanks!

thanks nick!

1. overlaying the map on other content. for iOS, wouldn't this work:

view.opaque = NO;

view.backgroundColor = [UIColor clearColor];

and then in the gl render code:

glClearColor(0.0f, 0.0f, 0.0f, 0.0f);

2. not really needed, just asking

3. cool, thanks. is this available in beta1 right now?

when is beta2 going to be released?

Hey Brian,

Here's what I was able to dig up for you:

* You will be able to change the color at beta 2 although a transparent one will probably not work because of the way OpenGL renders. Do you have a specific use-case?
* The Runtime uses a CAEGLView the context is kept private. Again, what's the use case you're looking at?
* The map can indeed have no basemap.

I'd be interested to learn a little more about what you're trying to do that you want the transparency and the OpenGL context.

Hope this helps.

Nick.
