Functions

func GetName

func GetName(sensors []string, index int) (string, error)

GetName returns the name of the sensor based on its index in the sensor array.

func GetPNGImage

func GetPNGImage(ctx context.Context, cam camera.Camera) ([]byte, func(), error)

GetPNGImage first attempts to get a lazy PNG image. If the image is not a lazy PNG, the function expects it to be an YCBCR image. If it is neither a lazy PNG nor an YCBCR, the function errors out. The returned function is a release function that must be called once the caller of GetPNGImage is done using the image.
