What kind of software can I use for interior decorating?

I looking for the software that you use with a digital camera. For example; if I want to see what type of blinds would look good on my window, I could take a picture of my window and then download it to my computer and then use the software to try different types of styles I could use.

You can do all of that with the software below. You can download a demo, where some of the functions are disabled.
