# <span style={{ 'color': 'gray' }}>module</span>  pixeltable.functions.reve

Pixeltable [UDFs](https://docs.pixeltable.com/platform/udfs-in-pixeltable) that wrap [Reve](https://app.reve.com/) image
generation API. In order to use them, the API key must be specified either with `REVE_API_KEY` environment variable,
or as `api_key` in the `reve` section of the Pixeltable config file.

## <span style={{ 'color': 'gray' }}>udf</span>  create()

```python Signature theme={null}
@pxt.udf
create(
    prompt: pxt.String,
    *,
    aspect_ratio: pxt.String | None = None,
    version: pxt.String | None = None,
    model_kwargs: pxt.Json | None = None
) -> pxt.Image
```

Creates an image from a text prompt.

This UDF wraps the `https://api.reve.com/v1/image/create` endpoint. For more information, refer to the official
[API documentation](https://api.reve.com/console/docs/create).

**Parameters:**

* **`prompt`** (`pxt.String`): prompt describing the desired image
* **`aspect_ratio`** (`pxt.String | None`): desired image aspect ratio, e.g. '3:2', '16:9', '1:1', etc.
* **`version`** (`pxt.String | None`): specific model version to use. Latest if not specified.
* **`model_kwargs`** (`pxt.Json | None`): additional keyword arguments to pass to the Reve API.

**Returns:**

* `pxt.Image`: A generated image

**Examples:**

Add a computed column with generated square images to a table with text prompts:

```python  theme={null}
t.add_computed_column(img=reve.create(t.prompt, aspect_ratio='1:1'))
```

## <span style={{ 'color': 'gray' }}>udf</span>  edit()

```python Signature theme={null}
@pxt.udf
edit(
    image: pxt.Image,
    edit_instruction: pxt.String,
    *,
    version: pxt.String | None = None,
    model_kwargs: pxt.Json | None = None
) -> pxt.Image
```

Edits images based on a text prompt.

This UDF wraps the `https://api.reve.com/v1/image/edit` endpoint. For more information, refer to the official
[API documentation](https://api.reve.com/console/docs/edit)

**Parameters:**

* **`image`** (`pxt.Image`): image to edit
* **`edit_instruction`** (`pxt.String`): text prompt describing the desired edit
* **`version`** (`pxt.String | None`): specific model version to use. Latest if not specified.
* **`model_kwargs`** (`pxt.Json | None`): additional keyword arguments to pass to the Reve API.

**Returns:**

* `pxt.Image`: A generated image

**Examples:**

Add a computed column with catalog-ready images to the table with product pictures:

```python  theme={null}
t.add_computed_column(
    catalog_img=reve.edit(
        t.product_img,
        'Remove background and distractions from the product picture, improve lighting.',
    )
)
```

## <span style={{ 'color': 'gray' }}>udf</span>  remix()

```python Signature theme={null}
@pxt.udf
remix(
    prompt: pxt.String,
    images: pxt.Json[(Image, *, aspect_ratio: pxt.String | None = None, version: pxt.String | None = None, model_kwargs: pxt.Json | None = None
) -> pxt.Image
```

Creates images based on a text prompt and reference images.

The prompt may include `<img>0</img>`, `<img>1</img>`, etc. tags to refer to the images in the `images` argument.

This UDF wraps the `https://api.reve.com/v1/image/remix` endpoint. For more information, refer to the official
[API documentation](https://api.reve.com/console/docs/remix)

**Parameters:**

* **`prompt`** (`pxt.String`): prompt describing the desired image
* **`images`** (`pxt.Json[(Image`): list of reference images
* **`aspect_ratio`** (`Any`): desired image aspect ratio, e.g. '3:2', '16:9', '1:1', etc.
* **`version`** (`Any`): specific model version to use. Latest by default.
* **`model_kwargs`** (`Any`): additional keyword arguments to pass to the Reve API.

**Returns:**

* `pxt.Image`: A generated image

**Examples:**

Add a computed column with promotional collages to a table with original images:

```python  theme={null}
t.add_computed_column(
    promo_img=(
        reve.remix(
            'Generate a product promotional image by combining the image of the product'
            ' from <img>0</img> with the landmark scene from <img>1</img>',
            images=[t.product_img, t.local_landmark_img],
            aspect_ratio='16:9',
        )
    )
)
```
