The PrimitiveBoundingBox node creates a simple rectangular area defined by its position and size. It takes X and Y coordinates for the top-left corner, along with width and height values, and outputs a bounding box data structure that can be used by other nodes in a workflow.

## Inputs

| Parameter | Data Type | Required | Range     | Description                                                                |
| --------- | --------- | -------- | --------- | -------------------------------------------------------------------------- |
| `x`       | INT       | No       | 0 to 8192 | The X-coordinate for the top-left corner of the bounding box (default: 0). |
| `y`       | INT       | No       | 0 to 8192 | The Y-coordinate for the top-left corner of the bounding box (default: 0). |
| `width`   | INT       | No       | 1 to 8192 | The width of the bounding box (default: 512).                              |
| `height`  | INT       | No       | 1 to 8192 | The height of the bounding box (default: 512).                             |

## Outputs

| Output Name    | Data Type     | Description                                                                                          |
| -------------- | ------------- | ---------------------------------------------------------------------------------------------------- |
| `bounding_box` | BOUNDING\_BOX | A data structure containing the `x`, `y`, `width`, and `height` properties of the defined rectangle. |
