ppt2fig-exportPPT转PDF导出

Use ppt2fig to export slide pages to PDF.

Workflow:

1. 1. Confirm the source presentation path exists.
2. Decide the page selection string.

Examples: 1, 2, 1,3,5-7

1. 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

1. 4. Decide whether to crop.

- Use default cropping for paper figures. - Use --no-crop only when the user explicitly wants original margins.

1. 5. Run the command.
2. Return the output PDF path and any backend-specific notes.

Preferred commands:

CODEBLOCK0

If ppt2fig is not on PATH, try:

CODEBLOCK1

If the binary is installed by OpenClaw or ClawHub, the helper script will first look in ~/.openclaw/tools/ppt2fig-export/ for the downloaded GitHub Release executable. If that is not present, it falls back to PATH, then to python -m ppt2fig:

CODEBLOCK2

Behavior notes:

• - auto backend priority is LibreOffice > WPS > PowerPoint.
• INLINECODE16 prints what the current machine can use.
• Page numbers are 1-based.
• Output defaults to <input>.pages_<page-spec>.pdf when -o is omitted.
• PowerPoint image quality is limited by Microsoft's export API; --powerpoint-intent print is the highest-quality option exposed by the CLI.

Useful checks:

CODEBLOCK3

Use the second command only when you need to validate page count or explain an out-of-range error.
