        The getSamples operation is performed on an image service resource.
        The getSamples operation is supported by both mosaic dataset and raster
        dataset image services.
        The result of this operation includes sample point locations, pixel
        values, and corresponding spatial resolutions of the source data for a
        given geometry. When the input geometry is a polyline, envelope, or
        polygon, sampling is based on sampleCount or sampleDistance; when the
        input geometry is a point or multipoint, the point or points are used
        directly.
        The number of sample locations in the response is based on the
        sampleDistance or sampleCount parameter and cannot exceed the limit of
        the image service (the default is 1000, which is an approximate limit).

        Inputs:

        geometry - A geometry that defines the location(s) to be sampled. The
         structure of the geometry is the same as the structure of the JSON
         geometry objects returned by the ArcGIS REST API. Applicable geometry
         types are point, multipoint, polyline, polygon, and envelope. When
         spatialReference is omitted in the input geometry, it will be assumed
         to be the spatial reference of the image service.

        geometryType - The type of geometry specified by the geometry parameter.
         The geometry type can be point, multipoint, polyline, polygon, or envelope.
         Values: esriGeometryPoint | esriGeometryMultipoint | esriGeometryPolyline |
         esriGeometryPolygon | esriGeometryEnvelope

        sampleDistance - The distance interval used to sample points from the
         provided path. The unit is the same as the input geometry. If neither
         sampleCount nor sampleDistance is provided, no densification can be done
         for paths (polylines), and a default sampleCount (100) is used for areas
         (polygons or envelopes).

        sampleCount - The approximate number of sample locations from the provided
         path. If neither sampleCount nor sampleDistance is provided, no
         densification can be done for paths (polylines), and a default
         sampleCount (100) is used for areas (polygons or envelopes).

        mosaicRule - Specifies the mosaic rule defining the image sort order.
         Additional filtering can be applied to the where clause and FIDs of a
         mosaic rule.

        pixelSize - The raster that is visible at the specified pixel size in the
         mosaic dataset will be used for sampling. If pixelSize is not specified,
         the service's pixel size is used.
         The structure of the esri_codephpixelSize parameter is the same as the
         structure of the point object returned by the ArcGIS REST API. In addition
         to the JSON structure, you can specify the pixel size with a simple
         comma-separated syntax.

        returnFirstValueOnly - Indicates whether to return all values at a point,
         or return the first non-NoData value based on the current mosaic rule.
         The default is true.

        interpolation - This parameter was added at 10.3. The resampling method.
         Default is nearest neighbor.

        outFields - This parameter was added at 10.3. The list of fields to be
         included in the response. This list is a comma-delimited list of field
         names. You can also specify the wildcard character (*) as the value of
         this parameter to include all the field values in the results.
