Description

2D texture zoom and pan camera controller.

Allows for freely moving around and zooming into a 2D texture using an orthographic camera. Use the 'frameTexture' function to adjust the scale and position of your texture, ensuring it fits perfectly in the viewport.

This component updates the projection and transform matrix of an orthographic camera, based on pointer input events. It therefore requires the following components to be present on the same entity.

a nap::Transform component
a nap::PointerInputComponent
a nap::OrthoCameraComponent

After calling 'frameTexture':

The texture is placed at a depth of (z)0.
The camera is placed at (xy)0 at a depth of (z)5.
The camera planes will match the size of the viewport.
The near and far clipping planes are setup to capture the framed texture.

Not calling 'frameTexture' allows you to use your own texture scale and orthographic camera settings. Note that for the component to work properly it can't have any parent transform, if it does the the result is undefined.
