In my workflow, I often have to take an image that I've created in another program (a 3D program). I set the background color there to be distinct from the object I want so that I can select it and make it transparent. In AD, the process (the best one I could find) is the switch to Pixel, Rasterize, then Select -> Select Sampled Colors. When I select the background color, the marquee does indeed seem to properly select the object. Unfortunately, it doesn't really work this way. If I cut (intending to cut out the background) color is lost from the object as well. If I invert selection and cut (intending to cut the object for use elsewhere in AD) some of the background comes as if some of its color were still present. I want the marquee to represent a clean separation between object and background so I can place my images with other layers in a final graphic file. Essentially, I'm trying to treat "Select Sampled Colors" like magic wand. Is there a way to do this? The invert selection option seems to work better except that I still get a grayish, partially transparent box background instead of a fully transparent background.
