Mask

Zusammenfassung

Creates a raster object by specifying one or more NoData values or a range of valid pixel values.

Diskussion

For more information about how this function works, see the Mask raster function.

The referenced raster dataset for the raster object is temporary. To make it permanent, you can call the raster object's save method.

Syntax

Mask (raster, {no_data_values}, {included_ranges}, {no_data_interpretation})

Parameter	Erläuterung	Datentyp
raster	The input raster.	Raster
no_data_values [no_data_values,...]	The NoData value or list of values. Values can be type Double or Integer. (Der Standardwert ist None)	Double
included_ranges [included_ranges,...]	The range of valid pixel values to be included in the output raster. Values can be type Double or Integer. (Der Standardwert ist None)	Double
no_data_interpretation	Specifies how the NoData values will be displayed in the output raster. 0—All—The NoData values you specify for each band must occur in the same cell for the output image to contain the NoData cell. 1—Any—If the NoData value you specify occurs for a cell in a specified band, that cell in the output image will be NoData. (Der Standardwert ist None)	Integer

Rückgabewert

Codebeispiel

Mask example

Masks a NoData value within a specified range of pixel values.

import arcpy

out_Mask_raster = arcpy.ia.Mask("Landsat8.tif", no_data_values = 6, included_ranges = [3,9])
