This node allows you to stitch two images together in a specified direction (up, down, left, right), with support for size matching and spacing between images.

## Inputs

| Parameter Name | Description | Data Type | Input Type | Default | Range |
| --- | --- | --- | --- | --- | --- |
| `image1` | The first image to be stitched | IMAGE | Required | - | - |
| `image2` | The second image to be stitched, if not provided returns only the first image | IMAGE | Optional | None | - |
| `direction` | The direction to stitch the second image: right, down, left, or up | STRING | Required | right | right/down/left/up |
| `match_image_size` | Whether to resize the second image to match the dimensions of the first image | BOOLEAN | Required | True | True/False |
| `spacing_width` | Width of spacing between images, must be an even number | INT | Required | 0 | 0-1024 |
| `spacing_color` | Color of the spacing between stitched images | STRING | Required | white | white/black/red/green/blue |

> For `spacing_color`, when using colors other than "white/black", if `match_image_size` is set to `false`, the padding area will be filled with black

## Outputs

| Output Name | Description | Data Type |
| --- | --- | --- |
| `IMAGE` | The stitched image | IMAGE |

## Workflow Example

In the workflow below, we use 3 input images of different sizes as examples:

- image1: 500x300
- image2: 400x250
- image3: 300x300

![workflow](./asset/workflow.webp)

**First Image Stitch Node**

- `match_image_size`: false, images will be stitched at their original sizes
- `direction`: up, `image2` will be placed above `image1`
- `spacing_width`: 20
- `spacing_color`: black

Output image 1:

![output1](./asset/output-1.webp)

**Second Image Stitch Node**

- `match_image_size`: true, the second image will be scaled to match the height or width of the first image
- `direction`: right, `image3` will appear on the right side
- `spacing_width`: 20
- `spacing_color`: white

Output image 2:
