# PPTX creation, editing, and analysis

## Overview

A user may ask you to create, edit, or analyze the contents of a .pptx file. A .pptx file is essentially a ZIP archive containing XML files and other resources that you can read or edit. You have different tools and workflows available for different tasks.

## Reading and analyzing content

### Text extraction
If you just need to read the text contents of a presentation, you should convert the document to markdown:

```bash
# Convert document to markdown
python -m markitdown path-to-file.pptx
```

### Raw XML access
You need raw XML access for: comments, speaker notes, slide layouts, animations, design elements, and complex formatting. For any of these features, you'll need to unpack a presentation and read its raw XML contents.

#### Unpacking a file
`python ooxml/scripts/unpack.py <office_file> <output_dir>`

**Note**: The unpack.py script is located at `skills/pptx/ooxml/scripts/unpack.py` relative to the project root. If the script doesn't exist at this path, use `find . -name "unpack.py"` to locate it.

#### Key file structures
* `ppt/presentation.xml` - Main presentation metadata and slide references
* `ppt/slides/slide{N}.xml` - Individual slide contents (slide1.xml, slide2.xml, etc.)
* `ppt/notesSlides/notesSlide{N}.xml` - Speaker notes for each slide
* `ppt/comments/modernComment_*.xml` - Comments for specific slides
* `ppt/slideLayouts/` - Layout templates for slides
* `ppt/slideMasters/` - Master slide templates
* `ppt/theme/` - Theme and styling information
* `ppt/media/` - Images and other media files

#### Typography and color extraction
**When given an example design to emulate**: Always analyze the presentation's typography and colors first using the methods below:
1. **Read theme file**: Check `ppt/theme/theme1.xml` for colors (`<a:clrScheme>`) and fonts (`<a:fontScheme>`)
2. **Sample slide content**: Examine `ppt/slides/slide1.xml` for actual font usage (`<a:rPr>`) and colors
3. **Search for patterns**: Use grep to find color (`<a:solidFill>`, `<a:srgbClr>`) and font references across all XML files

## Creating a new PowerPoint presentation **without a template**

When creating a new PowerPoint presentation from scratch, use the **html2pptx** workflow to convert HTML slides to PowerPoint with accurate positioning.

### Design Principles

**CRITICAL**: Before creating any presentation, analyze the content and choose appropriate design elements:
1. **Consider the subject matter**: What is this presentation about? What tone, industry, or mood does it suggest?
2. **Check for branding**: If the user mentions a company/organization, consider their brand colors and identity
3. **Match palette to content**: Select colors that reflect the subject
4. **State your approach**: Explain your design choices before writing code

**Requirements**:
- ✅ State your content-informed design approach BEFORE writing code
- ✅ Use web-safe fonts only: Arial, Helvetica, Times New Roman, Georgia, Courier New, Verdana, Tahoma, Trebuchet MS, Impact
- ✅ Create clear visual hierarchy through size, weight, and color
- ✅ Ensure readability: strong contrast, appropriately sized text, clean alignment
- ✅ Be consistent: repeat patterns, spacing, and visual language across slides

#### Color Palette Selection

**Choosing colors creatively**:
- **Think beyond defaults**: What colors genuinely match this specific topic? Avoid autopilot choices.
- **Consider multiple angles**: Topic, industry, mood, energy level, target audience, brand identity (if mentioned)
- **Be adventurous**: Try unexpected combinations - a healthcare presentation doesn't have to be green, finance doesn't have to be navy
- **Build your palette**: Pick 3-5 colors that work together (dominant colors + supporting tones + accent)
- **Ensure contrast**: Text must be clearly readable on backgrounds

**Example color palettes** (use these to spark creativity - choose one, adapt it, or create your own):

1. **Classic Blue**: Deep navy (#1C2833), slate gray (#2E4053), silver (#AAB7B8), off-white (#F4F6F6)

#### Visual Details Options

**Geometric Patterns**:
- Diagonal section dividers instead of horizontal
- Asymmetric column widths (30/70, 40/60, 25/75)
- Rotated text headers at 90deg or 270deg
- Circular/hexagonal frames for images
- Triangular accent shapes in corners
- Overlapping shapes for depth

**Border & Frame Treatments**:
- Thick single-color borders (10-20pt) on one side only
- Double-line borders with contrasting colors
- Corner brackets instead of full frames
- L-shaped borders (top+left or bottom+right)
- Underline accents beneath headers (3-5pt thick)

**Typography Treatments**:
- Extreme size contrast (72pt headlines vs 11pt body)
- All-caps headers with wide letter spacing
- Numbered sections in oversized display type
- Monospace (Courier New) for data/stats/technical content
- Condensed fonts (Arial Narrow) for dense information
- Outlined text for emphasis

**Chart & Data Styling**:
- Monochrome charts with single accent color for key data
- Horizontal bar charts instead of vertical
- Dot plots instead of bar charts
- Minimal gridlines or none at all
