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, MRF, CRF, 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 and Compression Quality in the Environments. 
- This tool supports multidimensional raster data. To run the tool on each slice in the multidimensional raster and generate a multidimensional raster output, be sure to save the output to CRF. - Supported input multidimensional dataset types include multidimensional raster layer, mosaic dataset, image service, and CRF. 
Syntax
Rescale(in_raster, out_raster, x_scale, y_scale)
| Parameter | Explanation | Data Type | 
| in_raster | The input raster. | Mosaic Layer; Raster Layer | 
| out_raster | The 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 geoprocessing Environments. | Raster Dataset | 
| x_scale | The factor by which to scale the cell size in the x direction. The factor must be greater than zero. | Double | 
| y_scale | The factor by which to scale the cell size in the y direction. The factor must be greater than zero. | Double |
