Presentation Maker

What this skill does

# Presentation Maker

The Presentation Maker skill enables automated creation of professional PowerPoint presentations (.pptx) with custom layouts, themes, charts, images, and multimedia. Using libraries like `pptxgenjs`, this skill handles everything from simple slide decks to complex presentations with data visualizations and animations.

Create pitch decks, training materials, reports, project updates, and any presentation content programmatically. Support for master slides, themes, charts, tables, images, shapes, and speaker notes makes this a complete solution for presentation automation.

## Core Workflows

### Workflow 1: Create Basic Presentation
**Purpose:** Build a simple presentation with title and content slides

**Steps:**
1. Import `pptxgenjs` and create Presentation instance
2. Define presentation properties (title, author, company)
3. Add title slide with company branding
4. Add content slides with bullet points
5. Apply consistent theme and fonts
6. Add slide numbers
7. Export to .pptx file

**Implementation:**
```javascript
const PptxGenJS = require('pptxgenjs');

function createBasicPresentation(content, outputPath) {
  const pptx = new PptxGenJS();

  // Set presentation properties
  pptx.author = 'Company Name';
  pptx.company = 'Company Name';
  pptx.subject = content.subject;
  pptx.title = content.title;

  // Title slide
  let slide = pptx.addSlide();
  slide.background = { color: '2C3E50' };
  slide.addText(content.title, {
    x: 0.5,
    y: 2.5,
    w: '90%',
    h: 1.5,
    fontSize: 44,
    bold: true,
    color: 'FFFFFF',
    align: 'center'
  });
  slide.addText(content.subtitle, {
    x: 0.5,
    y: 4.0,
    w: '90%',
    fontSize: 24,
    color: 'BDC3C7',
    align: 'center'
  });

  // Content slides
  content.slides.forEach(slideData => {
    let slide = pptx.addSlide();

    // Title
    slide.addText(slideData.title, {
      x: 0.5,
      y: 0.5,
      w: '90%',
      h: 0.75,
      fontSize: 32,
      bold: true,
      color: '2C3E50'
    });

    // Bullet points
    slide.addText(slideData.bullets, {
      x: 0.5,
      y: 1.5,
      w: '90%',
      h: 4.0,
      fontSize: 18,
      bullet: true,
      color: '34495E'
    });

    // Slide number
    slide.addText(`${pptx.getSlideNumber()}`, {
      x: 9.0,
      y: 7.0,
      w: 0.5,
      h: 0.3,
      fontSize: 12,
      color: '95A5A6',
      align: 'right'
    });
  });

  pptx.writeFile({ fileName: outputPath });
}
```

### Workflow 2: Add Charts and Data Visualizations
**Purpose:** Create slides with embedded charts from data

**Steps:**
1. Create presentation
2. Prepare chart data (labels and values)
3. Add chart slide with title
4. Define chart type (bar, line, pie, scatter, etc.)
5. Configure chart options (colors, legend, axes)
6. Add data labels and formatting
7. Position chart on slide

**Implementation:**
```javascript
function createPresentationWithCharts(data, outputPath) {
  const pptx = new PptxGenJS();

  // Bar chart slide
  let slide = pptx.addSlide();
  slide.addText('Quarterly Revenue', {
    x: 0.5, y: 0.5, w: '90%', fontSize: 32, bold: true
  });

  const chartData = [
    {
      name: 'Revenue',
      labels: data.quarters,
      values: data.revenue
    }
  ];

  slide.addChart(pptx.ChartType.bar, chartData, {
    x: 1.0,
    y: 1.5,
    w: 8.0,
    h: 4.5,
    chartColors: ['2E74B5'],
    showTitle: false,
    showLegend: true,
    legendPos: 'b',
    valAxisMaxVal: Math.max(...data.revenue) * 1.2,
    dataLabelFormatCode: '$#,##0',
    showValue: true
  });

  // Pie chart slide
  slide = pptx.addSlide();
  slide.addText('Market Share', {
    x: 0.5, y: 0.5, w: '90%', fontSize: 32, bold: true
  });

  const pieData = [
    { name: 'Product A', labels: ['Share'], values: [35] },
    { name: 'Product B', labels: ['Share'], values: [28] },
    { name: 'Product C', labels: ['Share'], values: [22] },
    { name: 'Others', labels: ['Share'], values: [15] }
  ];

  slide.addChart(pptx.ChartType.pie, pieData, {
    x: 2.0,
    y: 1.5,
    w: 6.0,
    h: 4.5,
    showPercent: true,
    chartColors: ['2E74B5', '5DA5DA', '60BD68', 'F17CB0']
  });

  // Line chart for trends
  slide = pptx.addSlide();
  slide.addText('Growth Trend', {
    x: 0.5, y: 0.5, w: '90%', fontSize: 32, bold: true
  });

  const lineData = [
    {
      name: '2024',
      labels: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun'],
      values: [10, 15, 13, 18, 22, 25]
    },
    {
      name: '2025',
      labels: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun'],
      values: [12, 18, 16, 22, 27, 32]
    }
  ];

  slide.addChart(pptx.ChartType.line, lineData, {
    x: 1.0,
    y: 1.5,
    w: 8.0,
    h: 4.5,
    lineSmooth: true,
    chartColors: ['2E74B5', 'E74C3C']
  });

  pptx.writeFile({ fileName: outputPath });
}
```

### Workflow 3: Create Presentation from Template
**Purpose:** Use a master slide template for consistent branding

**Steps:**
1. Load or define master slide layouts
2. Set theme colors and fonts
3. Define slide layouts (title, content, two-column, etc.)
4. Create slides using predefined layouts
5. Apply company branding consistently
6. Add footer and logo to all slides
7. Export with template applied

**Implementation:**
```javascript
function createFromTemplate(content, outputPath) {
  const pptx = new PptxGenJS();

  // Define theme colors
  pptx.defineLayout({ name: 'CUSTOM', width: 10, height: 5.625 });
  pptx.layout = 'CUSTOM';

  // Define master slide
  const masterSlide = pptx.defineSlideMaster({
    title: 'MASTER_SLIDE',
    background: { color: 'FFFFFF' },
    objects: [
      // Company logo
      { image: { x: 0.5, y: 0.2, w: 1.0, h: 0.4, path: 'company-logo.png' } },
      // Footer
      { text: { text: 'Company Confidential', options: { x: 0.5, y: 5.0, fontSize: 10, color: '95A5A6' } } }
    ]
  });

  // Use master slide for content
  content.slides.forEach(slideData => {
    let slide = pptx.addSlide({ masterName: 'MASTER_SLIDE' });

    slide.addText(slideData.title, {
      x: 2.0, y: 0.5, w: 7.5, fontSize: 28, bold: true, color: '2C3E50'
    });

    slide.addText(slideData.content, {
      x: 2.0, y: 1.5, w: 7.5, fontSize: 16, color: '34495E'
    });
  });

  pptx.writeFile({ fileName: outputPath });
}
```

### Workflow 4: Add Images and Media
**Purpose:** Include images, shapes, and multimedia content

**Steps:**
1. Create presentation
2. Add image slides with captions
3. Resize and position images
4. Add shapes (rectangles, circles, arrows)
5. Layer elements with z-index
6. Add hyperlinks to images
7. Insert video placeholders (if supported)

**Implementation:**
```javascript
function createWithMedia(content, outputPath) {
  const pptx = new PptxGenJS();

  // Image slide
  let slide = pptx.addSlide();
  slide.addText(content.title, {
    x: 0.5, y: 0.5, fontSize: 32, bold: true
  });

  // Add image
  slide.addImage({
    path: content.imagePath,
    x: 1.5,
    y: 1.5,
    w: 7.0,
    h: 4.0,
    sizing: { type: 'contain', w: 7.0, h: 4.0 }
  });

  // Add caption
  slide.addText(content.caption, {
    x: 1.5,
    y: 5.7,
    w: 7.0,
    fontSize: 14,
    italic: true,
    align: 'center',
    color: '7F8C8D'
  });

  // Slide with shapes
  slide = pptx.addSlide();

  // Background shape
  slide.addShape(pptx.ShapeType.rect, {
    x: 0.5,
    y: 1.5,
    w: 9.0,
    h: 4.5,
    fill: { color: 'ECF0F1' },

  slide.addShape(pptx.ShapeType.rightArrow, {
    x: 1.0,
    y: 3.0,
    w: 2.0,
    h: 1.0,
    fill: { color: '3498DB' }
