# PPTX Skill v2.0

## Overview

Complete PowerPoint presentation creation and editing using `python-pptx`. Supports all common slide operations including text, images, charts, tables, and animations.

## Installation & Dependencies

### Required
```bash
pip install python-pptx pillow
```

### Optional
```bash
# For advanced chart support
pip install numpy

# For HTML conversion (advanced)
npm install puppeteer dom-to-pptx
```

## Quick Start

### Create First Presentation
```python
from pptx import Presentation

prs = Presentation()
slide = prs.slides.add_slide(prs.slide_layouts[0])
slide.shapes.title.text = "Hello World"
prs.save('presentation.pptx')
print("✓ Presentation created!")
```

### Add Content Slide
```python
from pptx import Presentation

prs = Presentation()

# Title slide
slide = prs.slides.add_slide(prs.slide_layouts[0])
slide.shapes.title.text = "My Presentation"
slide.placeholders[1].text = "Subtitle here"

# Content slide
slide = prs.slides.add_slide(prs.slide_layouts[1])
slide.shapes.title.text = "Agenda"
slide.placeholders[1].text = "• Point 1\n• Point 2\n• Point 3"

prs.save('output.pptx')
```

## Complete API Reference

### Slide Layouts

```python
from pptx import Presentation

prs = Presentation()

# Available layouts (indices may vary by template)
# 0 - Title Slide
slide = prs.slides.add_slide(prs.slide_layouts[0])
slide.shapes.title.text = "Title"
slide.placeholders[1].text = "Subtitle"

# 1 - Title and Content
slide = prs.slides.add_slide(prs.slide_layouts[1])
slide.shapes.title.text = "Heading"
slide.placeholders[1].text = "Content here"

# 2 - Section Header
slide = prs.slides.add_slide(prs.slide_layouts[2])

# 3 - Two Content
slide = prs.slides.add_slide(prs.slide_layouts[3])

# 4 - Comparison
slide = prs.slides.add_slide(prs.slide_layouts[4])

# 5 - Title Only
slide = prs.slides.add_slide(prs.slide_layouts[5])

# 6 - Blank
slide = prs.slides.add_slide(prs.slide_layouts[6])
```

### Text Formatting

```python
from pptx import Presentation
from pptx.util import Inches, Pt
from pptx.dml.color import RGBColor
from pptx.enum.text import PP_ALIGN

prs = Presentation()
slide = prs.slides.add_slide(prs.slide_layouts[1])

# Title formatting
title = slide.shapes.title
title.text = "Formatted Title"
title.text_frame.paragraphs[0].font.name = 'Arial'
title.text_frame.paragraphs[0].font.size = Pt(36)
title.text_frame.paragraphs[0].font.bold = True
title.text_frame.paragraphs[0].font.color.rgb = RGBColor(0, 0, 0)

# Content formatting
content = slide.placeholders[1]
tf = content.text_frame
tf.text = "First paragraph"

# Add paragraph with formatting
p = tf.add_paragraph()
p.text = "Second paragraph"
p.level = 0  # Indentation level
p.alignment = PP_ALIGN.LEFT

# Run-level formatting (within paragraph)
run = p.add_run()
run.text = "Bold text"
run.font.bold = True
run.font.size = Pt(14)
run.font.name = 'Arial'
run.font.color.rgb = RGBColor(0, 112, 192)  # Blue

run = p.add_run()
run.text = " and "

run = p.add_run()
run.text = "italic text"
run.font.italic = True
```

### Adding Images

```python
from pptx import Presentation
from pptx.util import Inches

prs = Presentation()
slide = prs.slides.add_slide(prs.slide_layouts[5])  # Blank layout

# Add image
left = top = Inches(1)
slide.shapes.add_picture(
    'image.jpg',
    left,
    top,
    width=Inches(5),
    height=Inches(3)  # Optional, maintains aspect ratio if omitted
)

# Add image with caption
slide.shapes.add_picture('logo.png', Inches(1), Inches(5), width=Inches(2))

# Add textbox for caption
txBox = slide.shapes.add_textbox(Inches(3.2), Inches(5), Inches(3), Inches(1))
tf = txBox.text_frame
tf.text = "Image caption here"

prs.save('with-image.pptx')
```

### Adding Tables

```python
from pptx import Presentation
from pptx.util import Inches
from pptx.dml.color import RGBColor

prs = Presentation()
slide = prs.slides.add_slide(prs.slide_layouts[5])

# Add table: 3 rows, 3 columns
rows = cols = 3
left = top = Inches(2)
width = Inches(6)
height = Inches(2)

table = slide.shapes.add_table(rows, cols, left, top, width, height).table

# Set column widths
table.columns[0].width = Inches(2)
table.columns[1].width = Inches(2)
table.columns[2].width = Inches(2)

# Fill data
table.cell(0, 0).text = 'Header 1'
table.cell(0, 1).text = 'Header 2'
table.cell(0, 2).text = 'Header 3'
table.cell(1, 0).text = 'Row 1'
table.cell(1, 1).text = 'Data 1'
table.cell(1, 2).text = 'Data 2'
table.cell(2, 0).text = 'Row 2'
table.cell(2, 1).text = 'Data 3'
table.cell(2, 2).text = 'Data 4'

# Format cells
cell = table.cell(0, 0)
cell.fill.solid()
cell.fill.fore_color.rgb = RGBColor(0, 112, 192)  # Blue header
cell.text_frame.paragraphs[0].font.color.rgb = RGBColor(255, 255, 255)
cell.text_frame.paragraphs[0].font.bold = True

# Center align all cells
for row in table.rows:
    for cell in row.cells:
        cell.text_frame.paragraphs[0].alignment = PP_ALIGN.CENTER

prs.save('with-table.pptx')
```

### Adding Charts

```python
from pptx import Presentation
from pptx.chart.data import CategoryChartData
from pptx.enum.chart import XL_CHART_TYPE
from pptx.util import Inches

prs = Presentation()
slide = prs.slides.add_slide(prs.slide_layouts[5])

# Prepare chart data
chart_data = CategoryChartData()
chart_data.categories = ['Q1', 'Q2', 'Q3', 'Q4']
chart_data.add_series('Revenue', (100000, 150000, 200000, 250000))
chart_data.add_series('Expenses', (80000, 100000, 120000, 140000))

# Add chart
x, y, cx, cy = Inches(1), Inches(1), Inches(8), Inches(5)
chart = slide.shapes.add_chart(
    XL_CHART_TYPE.COLUMN_CLUSTERED,  # Chart type
    x, y, cx, cy,
    chart_data
).chart

# Customize chart
chart.has_title = True
chart.chart_title.text_frame.text = 'Quarterly Financials'
chart.value_axis.has_major_gridlines = True
chart.category_axis.tick_labels.font.size = Pt(10)

prs.save('with-chart.pptx')
```

### Chart Types

```python
from pptx.enum.chart import XL_CHART_TYPE

# Available chart types
XL_CHART_TYPE.COLUMN_CLUSTERED      # Clustered column
XL_CHART_TYPE.COLUMN_STACKED        # Stacked column
XL_CHART_TYPE.BAR_CLUSTERED         # Clustered bar
XL_CHART_TYPE.LINE                  # Line chart
XL_CHART_TYPE.PIE                   # Pie chart
XL_CHART_TYPE.PIE_EXPLODED          # Exploded pie
XL_CHART_TYPE.AREA                  # Area chart
XL_CHART_TYPE.XY_SCATTER            # Scatter plot
XL_CHART_TYPE.BUBBLE                # Bubble chart

from pptx.util import Inches
from pptx.enum.shapes import MSO_SHAPE
from pptx.dml.color import RGBColor

prs = Presentation()
slide = prs.slides.add_slide(prs.slide_layouts[5])

# Add rectangle
shape = slide.shapes.add_shape(
    MSO_SHAPE.ROUNDED_RECTANGLE,
    Inches(1), Inches(1), Inches(3), Inches(2)
)
shape.fill.solid()
shape.fill.fore_color.rgb = RGBColor(0, 112, 192)
shape.line.color.rgb = RGBColor(0, 0, 0)

# Add text to shape
tf = shape.text_frame
tf.text = "Click Shape"
tf.paragraphs[0].font.color.rgb = RGBColor(255, 255, 255)
tf.paragraphs[0].alignment = PP_ALIGN.CENTER

## Error Handling

### Common Errors

#### Error: "Placeholder not found"
```python
# Solution: Check layout has the placeholder
slide = prs.slides.add_slide(prs.slide_layouts[0])
if len(slide.placeholders) > 1:
    slide.placeholders[1].text = "Subtitle"
```

#### Error: "Image not found"
```python
# Solution: Check file exists before adding
import os
if os.path.exists('image.jpg'):
    slide.shapes.add_picture('image.jpg', Inches(1), Inches(1))
else:
    print("Image file not found!")
```

#### Error: "Chart data error"
```python
# Solution: Ensure data categories and series match
chart_data = CategoryChartData()
chart_data.categories = ['Q1', 'Q2', 'Q3']  # Must match series length
chart_data.add_series('Revenue', (100, 150, 200))
```

## Best Practices

### 1. Use Master Slides for Consistency
```python
# Edit slide master for consistent branding
slide_master = prs.slide_master
title_layout = slide_master.slide_layouts[0]
```

### 2. Keep File Size Manageable
```python
# Compress images before adding
from PIL import Image
img = Image.open('large.jpg')
img.thumbnail((1920, 1080))
img.save('compressed.jpg', quality=85)
```

### 3. Use Standard Fonts
```python
# Use fonts available on most systems
title.text_frame.paragraphs[0].font.name = 'Arial'  # Safe choice
```

### 4. Limit Animations
```python
# python-pptx has limited animation support
# Create simple, clean slides instead
```

## Testing Your Setup

```python
# test-pptx.py
from pptx import Presentation
from pptx.util import Inches
import os

print("Testing PPTX setup...")

# Test 1: Create basic presentation
prs = Presentation()
slide = prs.slides.add_slide(prs.slide_layouts[0])
slide.shapes.title.text = "Test Presentation"
prs.save('test-output.pptx')
assert os.path.exists('test-output.pptx')
print("✓ Basic creation test passed")

# Test 2: Add content
slide = prs.slides.add_slide(prs.slide_layouts[1])
slide.shapes.title.text = "Content Slide"
slide.placeholders[1].text = "Test content"
prs.save('test-output.pptx')
print("✓ Content addition test passed")

# Test 3: Load and verify
prs = Presentation('test-output.pptx')
assert len(prs.slides) == 2
print("✓ Load and verify test passed")

# Cleanup
os.remove('test-output.pptx')
print("✓ All tests passed!")
```

Run test:
```bash
python test-pptx.py
```
