PPT Generator

This skill enables comprehensive PowerPoint presentation management through multiple approaches:

1. Python-based Creation: Use python-pptx library for programmatic generation with professional styling
2. Direct OOXML Editing: Unpack, modify XML content, and repack PPTX files for advanced control
3. Template-based Workflow: Leverage existing templates with content replacement

PPTX files are ZIP archives containing XML files and resources. This architecture enables both high-level creation and low-level manipulation.

Implementation

The skill uses Python with the python-pptx library to process PowerPoint files. Run the processing script:

python scripts/create_ppt.py [options]

Script Usage

The script supports multiple ways to create presentations:

1. Simple command-line creation:

python scripts/create_ppt.py --output presentation.pptx --title "My Presentation"

2. JSON-based content definition:

python scripts/create_ppt.py --output presentation.pptx --json slides.json

3. Enhanced command-line creation with color scheme:

python scripts/create_ppt.py --output presentation.pptx --title "My Presentation" --color-scheme feedmob

4. Presentation with background image:

python scripts/create_ppt.py --output presentation.pptx --title "My Presentation" --background-image "bg.jpg"

5. Presentation with automatic backgrounds and logos (NEW):

python scripts/create_ppt.py --output presentation.pptx --title "My Presentation" --color-scheme feedmob

6. Disable automatic backgrounds or logos:

python scripts/create_ppt.py --output presentation.pptx --title "My Presentation" --no-auto-backgrounds
python scripts/create_ppt.py --output presentation.pptx --title "My Presentation" --no-auto-logos

The script will:

• Create a new PowerPoint presentation with professional styling
• Apply FeedMob or Binance color scheme by default (or selected alternative theme)
• NEW: Automatically select background images based on slide content (enabled by default)
• NEW: Automatically add logos to slides without backgrounds (enabled by default)
• Add slides with enhanced typography and layout
• Insert text and images with proper formatting
• Save the final .pptx file
• Handle errors gracefully with clear messages

Usage Examples

Create a FeedMob-branded presentation:

Create a PowerPoint presentation about FeedMob platform using FeedMob color scheme

Create a professional presentation:

Create a PowerPoint presentation about project status (uses Binance style by default)

Add slides with enhanced styling:

Generate a PPT with title slide and 3 content slides about quarterly results (uses FeedMob styling)

Create presentation with section headers:

Make a PowerPoint from this outline: Introduction, Features, Benefits, Conclusion with section headers (uses FeedMob theme)

Create comparison slides:

Create a presentation comparing our product vs competitors using FeedMob colors

Add images with effects:

Create a FeedMob presentation and add the logo image to the title slide with shadow effects

Requirements

• Python 3.6 or higher
• python-pptx library (>=0.6.21)
• Image files must exist at specified paths (for image insertion)

Output

• A .pptx file saved to the specified location
• Standard PowerPoint format compatible with Microsoft PowerPoint, LibreOffice, and Google Slides
• Preserves all formatting and layout settings

OOXML Direct Manipulation

For advanced editing beyond python-pptx capabilities, directly manipulate the OOXML structure:

Unpacking PPTX

# PPTX files are ZIP archives
unzip presentation.pptx -d unpacked/

Key OOXML Files

• ppt/presentation.xml - Slide order and IDs
• ppt/slides/slide*.xml - Individual slide content
• ppt/slideLayouts/ - Layout templates
• ppt/media/ - Embedded images
• [Content_Types].xml - File type declarations
• ppt/_rels/presentation.xml.rels - Slide relationships

Common Operations

Rearrange Slides: Modify <p:sldId> sequence in presentation.xml

Replace Text: Edit text within <a:t> tags in slide XML files

Duplicate Slides: Copy slide XML and update IDs in relationships

Delete Slides: Remove references from presentation.xml, relationships, and Content_Types

Repacking PPTX

cd unpacked/
zip -r ../modified.pptx * -x "*.DS_Store"

Critical: Validate OOXML structure before repacking. Incorrect XML causes corrupted files.

Design Principles

Follow these principles for professional presentations:

Content-Informed Design

• Design should serve content, not overshadow it
• Use strong visual hierarchy
• Maintain readable contrast (WCAG AA minimum)
• Use web-safe fonts (Arial, Helvetica, Times New Roman, Georgia)

Typography Standards

• Title: ≥28pt for readability
• Body: ≥18pt minimum
• Consistent font family throughout
• Limited font variations (2-3 weights max)

Color Guidelines

• 60-30-10 Rule: 60% primary, 30% secondary, 10% accent
• Maximum 4 colors per chart
• Consistent color mapping across visualizations
• Test contrast ratios for accessibility

Layout Optimization

• 6x6 Rule: Max 6 lines per slide, 6 words per line
• 20% Margins: Minimum white space for readability
• Grid Alignment: Use 12x8 grid for element positioning
• Visual Balance: Distribute weight evenly across slide

Recommended Color Palettes

Choose palettes that match presentation tone:

Professional Business: Navy (#1a3a5c), Gray (#6b7280), Blue (#3b82f6) Technology: Teal (#00B5AD), Purple (#8b5cf6), Cyan (#06b6d4) Corporate: Charcoal (#374151), Gold (#f59e0b), White (#ffffff) Modern: Black (#000000), Coral (#EE6969), Mint (#10b981)

Best Practices

Planning

• Define Structure First: Outline slide flow before detailed content
• Content-Informed Design: Let content guide design choices
• Consistent Theme: Maintain visual consistency throughout

Implementation

• Use Appropriate Tools: python-pptx for creation, OOXML for complex edits
• Validate Early: Check output after each major change
• Keep Text Concise: Follow 6x6 rule for readability
• Optimize Assets: Compress images before insertion

Quality Assurance

• Test Compatibility: Open in PowerPoint, LibreOffice, Google Slides
• Check Accessibility: Verify contrast ratios and font sizes
• Validate OOXML: Ensure no corrupted relationships or missing files
• Review on Device: Test on actual presentation display

Requirements

Python Environment:

• Python 3.6+
• python-pptx >= 0.6.21

Optional Tools:

• markitdown (text extraction)
• unzip/zip (OOXML manipulation)
• LibreOffice (validation and conversion)

For OOXML manipulation details, see REFERENCE.md.
