Hi all,

I would like to save a CCColorLayer as a png on Android and iOS. The layer contains a CCSprite and a CCRenderTexture.
With CCRenderTexture in Monogame it's not possible to get the png with saveAsPng() for Android and iOS.
And I don't seem to find the way to work with glReadPixels in C#.

Is there anyone who tried this already an has an example of how to do it?
Or are there any other suggestions?

Thanks in advance,

Change the manner in which you display the layer.

Use the CCRenderTexture to render the entire scene, then pull out the texture and save it. You can find a sample of this in the tests:

As far as I can see this only works on Windows.

The function SaveAsPng() is not implemented for Texture2d for Android and iOS.

Or am I missing an update?

They will come soon - MonoGame is working on adding a light weight PNG library. When that happens then we'll get PNG support across the platforms.

The iOS side should work. I am surprised it does not have a CG version of PNG writing....
