How do I?

I want to change size of the child view when zoom in event applied. How it can be done properly?

void onChangedSize(){ // function must be called
}

You can add a ZoomEngine.Listener to the ZoomEngine to get updates when the internal matrix is updated (due to pan or zoom) and then maybe use setContentSize on the engine to change the dimensions? Not sure what your goal with this is though. Also note that this might cause an infinite loop.

I did it , its goes to infinite. Could you show working example?

markusressel commented 3 years ago

What is your goal with this? Why do you need this? Are you sure you need to do this?

I cannot think of a use case that requires what you are describing.

I think it is more helpful if you could provide an example of what you are trying to achieve first :smile:

Goal is to change surfaceview inside zoomlayout. I am using textures mipmapping or just HD images and i want to change glViewPort with zoom for showing images with better quality.

markusressel commented 3 years ago

Are you using ZoomSurfaceView?

Yahor10 commented 3 years ago

I am using ZoomContainer (ZoomLayout)
