# Outpainting prompts
<a name="prompting-image-outpainting"></a>

Outpainting is used to replace the background of an image. For best results, outpainting prompts should describe what you would like the *whole* image to look like, including the parts of the image that will not be changed.

The following example uses a `text` value of *"a coffee maker in a sparse stylish kitchen, a single plate of pastries next to the coffee maker, a single cup of coffee".*

**Input Image**

**Mask Prompt**: *"coffee maker"*

**Result**
