The ImageScaleBy node is designed for upscaling images by a specified scale factor using various interpolation methods. It allows for the adjustment of the image size in a flexible manner, catering to different upscaling needs.

## Inputs

| Parameter | Description | Data Type |
| --- | --- | --- |
| `image` | The input image to be upscaled. This parameter is crucial as it provides the base image that will undergo the upscaling process. | `IMAGE` |
| `upscale_method` | Specifies the interpolation method to be used for upscaling. The choice of method can affect the quality and characteristics of the upscaled image. | COMBO[STRING] |
| `scale_by` | The factor by which the image will be upscaled. This determines the increase in size of the output image relative to the input image. | `FLOAT` |

## Outputs

| Parameter | Description | Data Type |
| --- | --- | --- |
| `image` | The upscaled image, which is larger than the input image according to the specified scale factor and interpolation method. | `IMAGE` |
