I am making figures for a report that require stacking a few scans on top of each other. The program that processes data allows you to export the spectra as a bitmap file. I have been placing them into a word doc to move them off of the computer attached to the instrument (not connected to internet). I then put them on my computer, save each image as a pdf and export them into ai. The scans look like this:
I want to extract just the line and place several on one image to compare but I can't figure out how to do that. Trace ends up somewhat lumpy and I can't change the color of the line or isolate it as a single object. Is there another way I should be exporting the scans? Or another tool in illustrator?
