Raster Band properties

Synthèse

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".

Propriétés

Propriété	Explication	Type de données
height (Lecture seule)	The number of rows.	Integer
isInteger (Lecture seule)	Indicates whether the raster band has integer type.	Boolean
meanCellHeight (Lecture seule)	The cell size in y direction.	Double
meanCellWidth (Lecture seule)	The cell size in x direction.	Double
noDataValue (Lecture seule)	The NoData value of the raster band.	String
pixelType (Lecture seule)	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 (Lecture seule)	The index of the field.	Integer
tableType (Lecture seule)	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 (Lecture seule)	The number of columns.	Integer

Exemple de code

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)
