# window_from_bounds

```python theme={"system"}
def window_from_bounds(
    geotiff: GeoTIFF,
    bounds: tuple[float, float, float, float],
    *,
    crs: str | int | CRS | Proj,
    require_fully_contained: bool = False,
) -> Window
```

Convert geographic bounds to an outward-rounded GeoTIFF pixel window clipped to the image.

<Note>
  This function requires Python 3.11 or newer and is imported from
  `tilebox.storage.geotiff`.
</Note>

## Parameters

<ParamField path="geotiff" type="GeoTIFF">
  The open async-geotiff image.
</ParamField>

<ParamField path="bounds" type="tuple[float, float, float, float]">
  Coordinates in `(left, bottom, right, top)` order.
</ParamField>

<ParamField path="crs" type="str | int | CRS | Proj">
  The coordinate reference system of `bounds`.
</ParamField>

<ParamField path="require_fully_contained" type="bool">
  Whether to reject bounds that extend beyond the image instead of clipping
  them. Defaults to `False`.
</ParamField>

## Returns

An async-geotiff `Window` containing every pixel touched by the bounds.
