MoveLayer

Zusammenfassung

Provides the ability to move a layer to a specific location within a data frame or group layer in a map document (.mxd).

Beschreibung

MoveLayer will move a layer within a data frame and also within group layers in the same data frame. The moved_layer and reference_layer must reside within the same data frame. A layer cannot be moved from one data frame to a different data frame even within the same map document. AddLayer, InsertLayer, and RemoveLayer functions can be used to accomplish this requirement.

Syntax

MoveLayer (data_frame, reference_layer, move_layer, {insert_position})

Parameter	Erläuterung	Datentyp
data_frame	A reference to a DataFrame object within which the layer will be moved.	DataFrame
reference_layer	A reference to a Layer object representing an existing layer that determines the location in relation to where the layer will be moved.	Layer
move_layer	A reference to a Layer object representing the layer to be moved.	Layer
insert_position	A constant that determines the placement of the moved layer relative to the referenced layer. AFTER —Inserts the new layer after or below the referenced layer BEFORE —Inserts the new layer before or above the referenced layer (Der Standardwert ist BEFORE)	String

Codebeispiel

MoveLayer example:

The following script will move a layer called Rivers above a reference layer called Lakes. Both layers are in a data frame called County Maps.

import arcpy
mxd = arcpy.mapping.MapDocument(r"C:\Project\Project.mxd")
df = arcpy.mapping.ListDataFrames(mxd, "County Maps")[0]
for lyr in arcpy.mapping.ListLayers(mxd, "", df):
    if lyr.name.lower() == "rivers":
        moveLayer = lyr
    if lyr.name.lower() == "lakes":
        refLayer = lyr
arcpy.mapping.MoveLayer(df, refLayer, moveLayer, "BEFORE")
mxd.saveACopy(r"C:\Project\Project2.mxd")
del mxd
