I'm a new Draftsight user and am having difficulty with a reference image.  I've successfully attached the image and now want to clip it.  I've used the "clipimage" command, which asks me to "specify" the reference image, but I have no idea how to do this.  Can anyone help?

As a second question, the attached reference image (a TIFF image) appears as white lines on a black background, and I would like to display it as black lines on a white background.  I've already switched the element colours for the model tab, but don't know how to do this for the attached reference image.
