Prompt

Initial Prompt

adobe-illustrator-scripting Create a script that will:

1. Select the top-most nested element layer in the "Screenshots" layer
2. Scale the selection proportionally, but set the widht to 360px
3. Determine Artboard action by:
  - If the selection is within the boundaries of an artboard, then:
    - Resize the Artboard to the selection
  - Else:
    - Create a new Artboard
    - Navigate to new Artboard
    - Resize the Artboard to the selection
4. Conditional Step
  - If a nested element layer exist below the current selection, then:
    - Select next nested element layer below the current selection
    - Repeat steps 2 through 4 (*this step*)
  - Else:
    - Throw as "Script Complete" alert, and done

Call it - "image-sizing.jsx"

Post Prompts

All post prompts were essentially:

Ran #file:image-sizing.jsx and got:

     ```
     No nested element layers with artwork were found in "Screenshots"
     ```

There are nested layers, items, images, groups, etc. in "Screenshots".
"Screenshots" is the top most layer, and is organized like:

     ```
     - Screenshots
       - `<Image>`
       - `<Image>`
       - `<Image>`
       - `<Group>`
       - `<Image>`
       - `<Image>`
       - `<Group>`
       - etc...
     ```

Results

It worked. I can't exactly illustrate with an Illustrator file, but the
script helped me size the images for the insturctions included in file.md,
of the support repo.

Good because - apart from making the Illustrator scripting skill and script,
this would have taken me like 5 to 10 minutes to do. Now it is done in
5 to 10 seconds.
