# [Company] PPT Template
 
Template: `assets/template.pptx` ([WIDTH]" x [HEIGHT]", [N] layouts)
 
## Creating Presentations
 
```python
from pptx import Presentation
 
prs = Presentation("path/to/skill/assets/template.pptx")
 
# DELETE all existing slides first
while len(prs.slides) > 0:
    rId = prs.slides._sldIdLst[0].rId
    prs.part.drop_rel(rId)
    del prs.slides._sldIdLst[0]
 
# Add slides from layouts
slide = prs.slides.add_slide(prs.slide_layouts[LAYOUT_IDX])
```
 
## Key Layouts
 
| Index | Name | Use For |
|-------|------|---------|
| [0] | [Layout Name] | [Cover/title slide] |
| [N] | [Layout Name] | [Content with bullets] |
| [N] | [Layout Name] | [Two-column layout] |
 
## Placeholder Mapping
 
**CRITICAL: Include exact positions (x, y coordinates) for each placeholder.**
 
### Layout [N]: [Name]
| idx | Type | Position | Use |
|-----|------|----------|-----|
| [idx] | TITLE (1) | y=[Y]" | Slide title |
| [idx] | BODY (2) | y=[Y]" | Subtitle/description |
| [idx] | BODY (2) | y=[Y]" | Footer |
| [idx] | BODY (2) | y=[Y]" | Source/notes |
 
### Content Area Boundaries
 
**Document the safe content area for custom shapes/tables/charts:**
 
```
Content Area (for Layout [N]):
- Left margin: [X]" (content starts here)
- Top: [Y]" (below subtitle placeholder)
- Width: [W]"
- Height: [H]" (ends before footer)
 
For 4-quadrant layouts:
- Left column: x=[X]", width=[W]"
- Right column: x=[X]", width=[W]"
- Top row: y=[Y]", height=[H]"
- Bottom row: y=[Y]", height=[H]"
```
 
**Why this matters:** Custom content (textboxes, tables, charts) must stay within these boundaries to avoid overlapping with template placeholders like titles, footers, and source lines.
 
## Filling Content
 
**Do NOT add manual bullet characters** - slide master handles formatting.
 
```python
# Fill title
for shape in slide.shapes:
    if hasattr(shape, 'placeholder_format'):
        if shape.placeholder_format.type == 1:  # TITLE
            shape.text = "Slide Title"
 
# Fill content with hierarchy (level 0 = header, level 1 = bullet)
for shape in slide.shapes:
    if hasattr(shape, 'placeholder_format'):
        idx = shape.placeholder_format.idx
        if idx == [CONTENT_IDX]:
            tf = shape.text_frame
            for para in tf.paragraphs:
                para.clear()
 
            content = [
                ("Section Header", 0),
                ("First bullet point", 1),
                ("Second bullet point", 1),
            ]
 
            tf.paragraphs[0].text = content[0][0]
            tf.paragraphs[0].level = content[0][1]
            for text, level in content[1:]:
                p = tf.add_paragraph()
                p.text = text
                p.level = level
```
 
## Example: Cover Slide
 
```python
slide = prs.slides.add_slide(prs.slide_layouts[[COVER_IDX]])
for shape in slide.shapes:
    if hasattr(shape, 'placeholder_format'):
        idx = shape.placeholder_format.idx
        if idx == [TITLE_IDX]:
            shape.text = "Company Name"
        elif idx == [SUBTITLE_IDX]:
            shape.text = "Presentation Title | Date"
```
 
## Example: Content Slide
 
```python
slide = prs.slides.add_slide(prs.slide_layouts[[CONTENT_IDX]])
for shape in slide.shapes:
    if hasattr(shape, 'placeholder_format'):
        ph_type = shape.placeholder_format.type
        idx = shape.placeholder_format.idx
        if ph_type == 1:
            shape.text = "Executive Summary"
        elif idx == [BODY_IDX]:
            tf = shape.text_frame
            for para in tf.paragraphs:
                para.clear()
            content = [
                ("Key Findings", 0),
                ("Revenue grew 40% YoY to $50M", 1),
                ("Expanded to 3 new markets", 1),
                ("Recommendation", 0),
                ("Proceed with strategic initiative", 1),
            ]
            tf.paragraphs[0].text = content[0][0]
            tf.paragraphs[0].level = content[0][1]
            for text, level in content[1:]:
                p = tf.add_paragraph()
                p.text = text
                p.level = level
```
