Examples
Demonstrates how to control RGB lighting of peripheral devices using the Windows.Devices.Lights and Windows.Devices.Lights.Effects APIs.
Demonstrates how to extract a single, representative color from a desktop screen and use it to illuminate LED lamps on a connected RGB device.
Remarks
- X corresponds to Width.
- Y corresponds to Height.
- Z corresponds to Depth.
Values are measured in meters.
The coordinate system is left-handed, with the origin at the front-top-left corner of the bounding box:
- +X extends to the right.
- +Y extends downward.
- +Z extends away from the user (into the device).
Origin of Positions is the upmost, top, left corner of the box.
Bounding box extents are derived from the device's HID LampArray descriptor, which reports dimensions in micrometers (µm). The WinRT API converts these values to meters (µm ÷ 1,000,000).
