Raster Band properties

サマリー

The Describe function returns the following properties for raster bands. The Table and Dataset property groups are also supported.

For a raster band, the Describe dataType property returns a value of "RasterBand".

プロパティ

プロパティ	説明	データ タイプ
height (読み取り専用)	The number of rows.	Integer
isInteger (読み取り専用)	Indicates whether the raster band has integer type.	Boolean
meanCellHeight (読み取り専用)	The cell size in y direction.	Double
meanCellWidth (読み取り専用)	The cell size in x direction.	Double
noDataValue (読み取り専用)	The NoData value of the raster band.	String
pixelType (読み取り専用)	The pixel type. U1—1 bit U2—2 bits U4—4 bits U8—Unsigned 8-bit integers S8—8-bit integers U16—Unsigned 16-bit integers S16—16-bit integers U32—Unsigned 32-bit integers S32—32-bit integers F32—Single-precision floating point F64—Double-precision floating point	String
primaryField (読み取り専用)	The index of the field.	Integer
tableType (読み取り専用)	The class names of the table. Value—Values in the table are used for values only, not for indexing. Index—Values in the table are used as indexes in the raster table. Invalid—Values are invalid.	String
width (読み取り専用)	The number of columns.	Integer

Raster band properties example

The following stand-alone script displays some properties for a raster band:

import arcpy

# Create a Describe object from the raster band
#
desc = arcpy.Describe("C:/data/preston.img/Band_1")

# Print some raster band properties
#
print("Height: %d" % desc.height)
print("Width:  %d" % desc.width)
print("Integer Raster: %s" % desc.isInteger)
