# **Creating Transparent Regions for Inpainting**
Inpainting is really cool. To do it, you start with an initial image and use a photoeditor to make one or more regions transparent (i.e. they have a "hole" in them). You then provide the path to this image at the dream> command line using the `-I` switch. Stable Diffusion will only paint within the transparent region.

There's a catch. In the current implementation, you have to prepare the initial image correctly so that the underlying colors are preserved under the transparent area. Many imaging editing applications will by default erase the color information under the transparent pixels and replace them with white or black, which will lead to suboptimal inpainting. You also must take care to export the PNG file in such a way that the color information is preserved.

If your photoeditor is erasing the underlying color information, `dream.py` will give you a big fat warning. If you can't find a way to coax your photoeditor to retain color values under transparent areas, then you can combine the `-I` and `-M` switches to provide both the original unedited image and the masked (partially transparent) image:
