AddRGBToByteArray()

static void DepictionEngine.ElevationUtility.AddRGBToByteArray ( byte  r, byte  g, byte  b, byte[]  rgbElevation, int  index  )

static

Add RGB bytes to a byte array.

Parameters

r	Red byte value.
g	Green byte value.
b	Blue byte value.
rgbElevation	The byte array to which we add the RGB values
index	The starting index in the array at which to insert the RGB values.

DecodeEsriLERCToFloat()

static float[] DepictionEngine.ElevationUtility.DecodeEsriLERCToFloat ( byte[]  elevation )

static

Decodes a byte array in Esri Limited Error Raster Compression(LERC) format into an array of elevation values.

Parameters

elevation

Elevation values, in Esri Limited Error Raster Compression(LERC) format.

Returns

An array of elevation values in world unit.

Exceptions

InvalidOperationException

DecodeToFloat()

static float DepictionEngine.ElevationUtility.DecodeToFloat ( byte  r, byte  g, byte  b, float  minElevation = Elevation::MIN_ELEVATION  )

static

Decode RGB bytes to elevation value.

Parameters

r	Red byte value.
g	Green byte value.
b	Blue byte value.
minElevation	The lowest point supported by the elevation encoding mode.

Returns

An Elevation value, in world units.

EncodeToRGBByte()

static void DepictionEngine.ElevationUtility.EncodeToRGBByte ( float  elevation, out byte  r, out byte  g, out byte  b, float  minElevation = Elevation::MIN_ELEVATION  )

static

Encode an elevation value to RGB bytes.

Parameters

elevation	An elevation value, in world units.
r	Red byte value.
g	Green byte value.
b	Blue byte value.
minElevation	The lowest point supported by the elevation encoding mode.

EncodeToRGBBytes()

static byte[] DepictionEngine.ElevationUtility.EncodeToRGBBytes ( float[]  elevation, int  width, int  height, float  minElevation = Elevation::MIN_ELEVATION  )

static

Encodes an array of elevation values, to texture RGB byte array.

Parameters

elevation	Elevation values, in world units.
width	Width of the texture.
height	Height of the texture.
minElevation	The lowest point supported by the elevation encoding mode.

Returns

A texture byte array.
