Class CMDatasetRaster extends CMDataset

CMDatasetRaster
Manages a raster that is represnted by a JSON object. This allows
for any type (N-Band, RGB, etc.) and any data type (INT32, FLOAT 32)
rasters to be managed in the client.d

The drawing functions maps the raster to the screen based on
the overall min max values.

Object Functions

Inherited From: CMDataset

Object Functions

SetBounds(NewBounds)

Check if the feature is visible in the view.
This should be called by subclasses but can also be called to limit a layer's bounds after loading.

Parameters:
    NewBounds - Bounds with format {XMin,XMax,YMin,YMax}

Bounds=GetBounds()

Returns the bounds of the data within the layer. Computed after loading the data.

Returns: Bounds - with format {XMin,XMax,YMin,YMax}

GetSampleFromRef()

Returns the value of a single pixel.
Used when raster has coordinates in the middle of thepixel - jjg when not used as a DEM

GetSampleFromRef_PixelsInCorners()

Returns the value of a single pixel.

GetPathArray()

returns an array of THREE.Vector3 objects with the z values set from the
associated DEM. New points will be added to the array when the line segments
cross a vertical or horizontal boundary between pixels.
