ppt2fig-export

Use ppt2fig to export slide pages to PDF.

Workflow:

1. Confirm the source presentation path exists.
2. Decide the page selection string. Examples: 1, 2, 1,3,5-7
3. Decide the backend. Defaults:
   • auto for normal use
   • libreoffice when cross-platform consistency matters
   • wps or powerpoint only when the user explicitly wants those backends
4. Decide whether to crop.
   • Use default cropping for paper figures.
   • Use --no-crop only when the user explicitly wants original margins.
5. Run the command.
6. Return the output PDF path and any backend-specific notes.
