Summary
Resizes a raster by the specified x and y scale factors.
Usage
The output size is multiplied by the scale factor for both the x and y directions. The number of columns and rows stays the same in this process, but the cell size is multiplied by the scale factor.
The scale factor must be positive.
A scale factor greater than one means the image will be rescaled to a larger dimension, resulting in a larger extent because of a larger cell size.
A scale factor less than one means the image will be rescaled to a smaller dimension, resulting in a smaller extent because of a smaller cell size.
You can save your output to BIL, BIP, BMP, BSQ, DAT, Esri Grid, GIF, IMG, JPEG, JPEG 2000, PNG, TIFF, or any geodatabase raster dataset.
When storing your raster dataset to a JPEG file, a JPEG 2000 file, or a geodatabase, you can specify a Compression Type type and Compression Quality within the Environment Settings.
Syntax
Rescale_management (in_raster, out_raster, x_scale, y_scale)
Parameter | Explanation | Data Type |
in_raster | The input raster. | Mosaic Layer; Raster Layer |
out_raster | Output raster dataset. When storing the raster dataset in a file format, you need to specify the file extension:
When storing a raster dataset in a geodatabase, no file extension should be added to the name of the raster dataset. When storing your raster dataset to a JPEG file, a JPEG 2000 file, a TIFF file, or a geodatabase, you can specify a Compression Type and Compression Quality in the Environment Settings. | Raster Dataset |
x_scale | The factor in which to scale the cell size in the x direction. The factor must be greater than zero. | Double |
y_scale | The factor in which to scale the cell size in the y direction. The factor must be greater than zero. | Double |
Code sample
Rescale example 1 (Python window)
This is a Python sample for the Rescale tool.
import arcpy
arcpy.Rescale_management("c:/data/image.tif", "c:/output/rescale.tif", "4", "4")
Rescale example 2 (stand-alone window)
This is a Python script sample for the Rescale tool.
