Hi Lloyd
Thank you for your reply to my last email, I just had a couple of questions
more about your email. I actually used C code to extract the geometry from the
image, but I was wondering if I can extract the geometry that I need directly
using DX ( I am sure I can, I just don't know how..)
The other thing is, assuming that I use the translation method i.e perform the
visualization and then place it on top of the original but translated image,
would you be able to give me some more detail about how I can go about doing
that in DX.
Thank you very much in advance

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).

Subject: [opendx-users] Placing a plot on an image
Hello Everybody
I am trying to do the following in DX. 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
