You can import the image, but then treat the colors or coordinate as data (e.g., Mark) and do various things as you suggest. You can then Collect the various visualizations with the original image and then render the result to have your derived information and the schematic. The downside is that you will pay a cost for rerendering the image. To avoid the image from obscuring the geometry you have created, you may wish to displace the image vertically (e.g., Translate) and/or assigning an opacity less than one (e.g., Color or Colormap->Color for variable opacity).
Depending on the geometry that you create, you might want to treat the image as a texture. That would make sense if you generated some sort of surface from the image. While this could be down as texturemap in hardware rendering, it may be easier to simply use the colors from the pixels of the image since you state your derived geometry is from the original image (e.g., Replace).

I have a schematic of a circuit and I would like to visualize the delays that exist on the wires connecting the different components in the circuit. The final product should be the schematic image with the wires raised and colored according to the delay that exists on them. I was able to extract the coordinates of the black pixels (the wires of the schematic are in black) in the original schematic and I would like to assign different scalar values (in this case the delays in nano seconds) to a certain range of pixel coordinates and then Glyph that scalar value on top of the original schematic image. Now since the the coordinates are of the actual pixels in the picture, their plot should be able to fit perfectly on top of the image and make it seem as a single 3D figure. Thank you very much in advance for your help and I hope to hear from you soon Karim ______________________________________________ FREE Personalized Email at Mail.com Sign up at http://www.mail.com/?sr=signup
