ArcGIS Help 10.2 - Edit Raster Function (Data Management)

Summary

Adds, replaces, or removes a raster function template to a mosaic dataset, items in a mosaic dataset, or a raster layer that contains a raster function. A raster function template defines a raster function chain. The template is stored as an rft.xml file, which can be exported from the Raster Function Editor.

Usage

To apply the rft.xml to items in a mosaic dataset, you must select the items in the attribute table or define a query using the Make Mosaic Layer tool.
The Raster Function Template Editor tool can be added to any toolbar using the Customized Mode window. The tool is located under the Command tab within the Raster category. To save out a raster function template, click File, then click Save; this will save an rft.xml file.
Database fragmentation and frequent data manipulation may increase the size of your mosaic dataset dramatically. If your database size is inflated due to constant transactions, you should run the Compact tool.

Syntax

EditRasterFunction_management (in_mosaic_dataset, {edit_mosaic_dataset_item}, {edit_options}, {function_chain_definition}, {location_function_name})

Parameter	Explanation	Data Type
in_mosaic_dataset	The input can be a mosaic dataset or a raster layer that contains a raster function.	Mosaic Layer; Raster Layer
edit_mosaic_dataset_item (Optional)	Choose whether to edit the mosaic dataset items. EDIT_MOSAIC_DATASET —The edits will affect the functions associated with the mosaic dataset. This is the default. EDIT_MOSAIC_DATASET_ITEM —The edits will affect the functions associated with the mosaic dataset items.	Boolean
edit_options (Optional)	Choose whether to insert a new raster function, replace an existing raster function chain, or remove the existing one. INSERT —Insert the functions above the location_function_name of the existing chain. The Raster Function Chain must be supplied in order to use this option. This is the default. REPLACE — Replace the existing function chain with the Raster Function Template specified in this tool. The Raster Function Chain must be supplied in order to use this option. REMOVE —Remove the existing raster function chain.	String
function_chain_definition (Optional)	The raster function template file (rft.xml). A raster function chain can be exported from the Raster Function Template Editor.	File
location_function_name (Optional)	The name of the function where the edits will take place. If you INSERT the function, then it will be inserted above the location_function_name. If you REPLACE the function, then it will replace the function that has been selected. If you REMOVE the function, then it will remove the function that has been selected.	String

Code Sample

EditRasterFunction example 1 (Python window)

This is a Python sample for EditRasterFunction.

import arcpy
arcpy.EditRasterFunction_management(
     "C:/Workspace/editfunction.gdb/md", "EDIT_MOSAIC_DATASET", 
     "INSERT", "C:/workspace/hillshade.rft.xml", "Stretch Function")

EditRasterFunction example 2 (stand-alone script)

This is a Python script sample for EditRasterFunction.

#Add raster function on top of mosaic dataset

import arcpy
arcpy.env.workspace = "C:/Workspace"

mdname = "editfunction.gdb/md"
editmode = "EDIT_MOSAIC_DATASET"
editmethod = "INSERT"
funcfile = "C:/workspace/hillshade.rft.xml"
funcname = "#"

arcpy.EditRasterFunction_management(mdname, editmode, editmethod, 
                                    funcfile, funcname)
