title: Rendering 16-bit NumpyTiles
|
|
shortdesc: Renders a multi-byte depth source image directly using WebGL.
|
|
docs: >
|
|
This example uses a <code>ol/source/DataTile</code> source to load multi-byte raster data in the
|
|
<a href="https://github.com/planetlabs/numpytiles-spec/">NumpyTile</a> format.
|
|
The source is rendered with a <code>ol/layer/WebGLTile</code> layer. Adjusting the sliders above
|
|
performs a contrast stretch by adjusting the style variables set on the layer.
