It could be possible with a cross-application script, but it's a little complex. Maybe I can make a test in a course of a couple of weeks.
Thanks for responding, Silly-V.
Another thought is to create a "drag-n-drop" script for Illustrator that would save a vector PDF of a JPG that is dropped onto the script.
I don't know if this is any simpler.
FYI… I have been testing a Mac-only Macro builder called "Keyboard Maestro". It allows me to "stack" actions (scripts, keyboard commands, etc.) together using a UI. I might be able to use it to combine several scripts more easily.
One thing I'm not experienced with yet is live tracing with Illustrator scripting, I think there were some preset issues a while back.
That's what I'd make first - and if you can actually record an action doing the live trace with preset, this would be a good solution right out of the gate, but I'm not sure that's recordable.
Don't know about Illustrator scripting and live trace presets, other than some threads on this forum.
My experience with Actions has been they did not recognize the custom Image Trace preset and ran the "default" preset instead. If the "default preset" can be changed that might be a good solution since this is our only use of image trace in our workflow.
I appreciate your time, Silly-V.
I'll try to test the tracing first, but it will take a few days.
