Raster Function Template

Raster function template containing one or more raster functions chained together to produce a processing workflow.

Properties

Property	Details
_object_id	The id of the raster function template.
aliases[]	Aliases for the `function` referenced in the template.
arguments	The arguments for the `function` referenced in the raster function template.
definition	A query definition to filter rasters when the layer's data source is a mosaic dataset.
description	The description of the raster function template.
function	The raster function referenced by the raster function template.
functionType	Defines whether the `function` is applied to a mosaic dataset. Indicates the level of the mosaic processing is used. Only applies to mosaic based image services. `0` - function is applied after mosaicking; `1` - function is applied on each raster item before mosaicking; `2` - function is applied to a group of raster items before mosaicking. Valid values: `0` `1` `2`
group	Group field name for item group function template
help	The short description of what the raster function template does.
name	Name of the raster function template.
properties	The properties used to define multidimensional dataset processing rules.
tag	Tag field name for item group function template .
thumbnail	Thumbnail url of the raster function template.
thumbnailEx	Base64 encoded thumbnail of the raster function template.
type	Type of the raster function template. Valid value of this property `RasterFunctionTemplate`
