PPT生成与修改

Generate and edit PowerPoint files with python-pptx, including slide creation, text replacement, and image replacement while preserving layout. Use when the user asks to create PPTs from structured content, update existing PPT content, or perform country/theme replacement in slides.

PPT Generate And Edit

Purpose

Provide a reusable Python skill for AI agents to:

• Create PPT files from structured input.
• Update existing PPT files with text/image replacement.
• Keep image layout stable (same position and size) during replacement.

Inputs

create_ppt

• title: presentation title.
• slides: array of slide objects:
  • title: slide title.
  • content: string or list of paragraphs.
  • image_prompt (optional): prompt for image generation.

update_ppt

• ppt_path: source .pptx path.
• replace_rules:
  • text_replace: dictionary for text replacement.
  • image_replace: dictionary for image replacement strategy.

Outputs

create_ppt

• Returns generated .pptx file path.

update_ppt

• Returns:
  • new_ppt_path: new .pptx output path.
  • replace_log: replacement details grouped by slide.

Module Structure

• main.py: external API for agent calls and demo entry.
• ppt_generator.py: PPT creation.
• ppt_editor.py: PPT text/image replacement.
• image_service.py: image generation abstraction (mock + extension points).
• utils.py: logging and path helpers.

Usage

python

from ppt_skill.main import create_ppt, update_ppt

slides = [
    {
        "title": "Brazil Overview",
        "content": ["Brazil is the largest country in South America."],
        "image_prompt": "Brazil skyline and national flag",
    }
]

ppt_path = create_ppt(title="Brazil Briefing", slides=slides)

result = update_ppt(
    ppt_path=ppt_path,
    replace_rules={
        "text_replace": {"Brazil": "Chile"},
        "image_replace": {"__all__": {"prompt": "Chile skyline and national flag"}},
    },
)
print(result["new_ppt_path"])

Notes

• Current generate_image() uses mock backend by default.
• DALL·E and Stable Diffusion integration points are reserved as TODO.
• Keep API fields stable for downstream agent compatibility.
