Hi Im using a small semi transparent ColorLayer to display a HUD. Is there a way to make the corners rounded? Thanks!

I'm about to attempt this myself. Maybe a PNG overlay with a transparent section in the middle to mask the ColorLayer?

Good luck,

Is clipping a possibilty in OpenGL? we can probably overide the -(void)draw method of the layer and use something like glScissor or something?

Thanks for the responses. I ended up just using a PNG as the background with rounded corners and the edges transparent. I then set the opacity to be semi transparent. I ended up getting the same effect I wanted without much effort.

I have extended the ColorLayer class so that it shows a rectangle with rounded corners. I also added the ability to draw/not draw a border using a different color.
Let me know if you are still interested.

Sorry to resurrect this thread, I've just been trying to find a solution to this issue as well. Can anybody lend a hand?

You can use the PNG workarround or create your own RoundedBorderColorLayer by overriding the draw method.
By using a PNG you'll be using less CPU but more memory. That's your choice :)

Do you know of any resources that would help me get started on how to do the drawing? I've looked before and haven't really found anything good, but I'm likely not searching for the right thing. I know how do do it with CoreGraphics, but this seems very different.

You can also use a CALayer and render it to a sprite in about 10 lines of code.

@fictorial - Nevermind that this is a 2 year old thread, but why would you go to all the trouble of using a CALayer, something that probably won't play nice with openGL and not just use the many Cocos2D native Scale9 implementations?
