Use the marble_pdf helper library. It builds HTML internally and converts to PDF via WeasyPrint — giving you full CSS styling with a simple Python API.
IMPORTANT: Always use the library helpers below. Never manually define CSS, color constants, or helper functions — the library handles all of this.
This skill is the complete API reference — all palettes, font pairs, and methods are documented below.
from marble_pdf import PDF
pdf = PDF(f'{WORKSPACE}/report.pdf', palette='ocean', fonts='modern')
# palette: midnight, forest, coral, terracotta, ocean, charcoal, teal, berry, sage, cherry
# fonts: classic, modern, bold, elegant, clean
# Or: PDF(path) for default light theme
| Method | Purpose |
|---|---|
PDF(path, theme, pagesize, margins, palette, fonts) | Create PDF. palette for named colors, fonts for font pair |
pdf.cover_page(title, subtitle, author, date) | Professional cover page with accent lines. Auto page break after |
pdf.title(text) | Title (28px, centered, primary) |
pdf.subtitle(text) | Subtitle (17px, centered, secondary). Use after title() |
pdf.heading(text, level) | Heading (level 1=18px, 2=14px). Use pdf.hr() after headings |
pdf.body(text) | Body paragraph (11px). Supports <b>, <i>, <font>, <sub>, <sup> |
pdf.caption(text) | Caption (9px, secondary) |
pdf.bullet(text) | Bullet list item. Supports HTML markup. Consecutive bullets auto-wrapped in <ul> |
pdf.spacer(height) | Vertical space (default 12px) |
pdf.hr(color) | Horizontal rule (default: primary) |
pdf.table(headers, rows, col_widths, first_col_align, header_bg, header_fg) | Themed table with alternating rows |
pdf.two_column(left_items, right_items, col_widths) | Side-by-side content layout |
pdf.image(path, width, align, max_height) | Insert image (auto-embedded as base64, height auto-scales) |
pdf.page_break() | Page break |
pdf.build(page_numbers=True) | Build final PDF. Call last |
When you need custom layouts beyond the builder API:
from marble_pdf import html_to_pdf, theme_css
css = theme_css('ocean', fonts='modern')
html = f"""<html>
<head><style>{css}</style></head>
<body>
<h2>Custom Report</h2><hr>
<p>Full <b>CSS control</b> — use any HTML elements, flexbox, grid, etc.</p>
<table>
<tr><th>Metric</th><th>Value</th></tr>
<tr><td>Revenue</td><td>$1.2M</td></tr>
</table>
<div class="page-break"></div>
<h2>Page 2</h2>
<p>Content continues...</p>
</body>
</html>"""
html_to_pdf(html, f'{WORKSPACE}/report.pdf')
Available CSS classes from theme_css(): .caption, .subtitle, .cover-page, .cover-author, .cover-date, .two-col + .col, .chart, .bullets, .page-break, .spacer, .spacer-sm, .spacer-lg, .spacer-xl.
Choose a palette that matches the content's mood — not the default blue:
| Palette | Primary | Best for |
|---|---|---|
midnight | Deep navy | Finance, enterprise, formal |
forest | Rich green | Sustainability, health, growth |
coral | Warm pink-red | Marketing, creative, consumer |
terracotta | Earthy brown | Luxury, real estate, hospitality |
ocean | Deep blue | Tech, analytics, professional |
charcoal | Dark gray | Minimal, corporate, neutral |
teal | Vibrant teal | Modern, SaaS, healthcare |
berry | Deep plum | Premium, beauty, fashion |
sage | Muted green-blue | Consulting, calm, wellness |
cherry | Bold red | Bold reports, urgency, food |
| Name | Heading / Body |
|---|---|
classic | Georgia / Calibri |
modern | Calibri / Calibri Light |
bold | Arial Black / Arial |
elegant | Cambria / Calibri |
clean | Trebuchet MS / Calibri |
For reports and long documents:
pdf.cover_page() (includes auto page break)pdf.hr() after section headingspdf.heading('1. Executive Summary')
pdf.hr()
pdf.body('Key findings...')
Use standard HTML tags in pdf.body() and pdf.bullet():
<b>bold</b>, <i>italic</i><font color="#34a853">colored text</font><sub>subscript</sub>, <sup>superscript</sup>| Scenario | figsize |
|---|---|
| Single chart per page | figsize=(7, 3) |
| Two charts per page | figsize=(7, 2.5) |
| Wide chart | figsize=(7, 2) |
| Maximum height | figsize height ≤ 4 (taller overflows) |
width — height auto-scales. Never pass explicit height.max_height param to constrain tall images (default 3.5").When the PDF needs real images returned by previous tool calls (ad thumbnails from facebook_analyze_ad_creative_by_id_or_url, competitor ad images from the ad library, video stills, etc.), pass each image URL as an attachment_url data source on the SAME advanced_analysis call. The runtime downloads them before your code runs — pdf.image() takes the local path:
# Tool call payload:
# dataSources: [
# {type: 'attachment_url', identifier: 'https://cdn.fbcdn.net/.../thumb_a.jpg', alias: 'creative_1'},
# {type: 'attachment_url', identifier: 'https://cdn.fbcdn.net/.../thumb_b.png', alias: 'creative_2'},
# ]
# In code:
from marble_pdf import PDF
pdf = PDF(f'{WORKSPACE}/report.pdf', palette='ocean')
pdf.heading('Top Performers')
pdf.hr()
pdf.image(f'{WORKSPACE}/creative_1.jpg', width=5)
pdf.caption('Figure 1: Outdoor Adventure (Video) — CTR 2.46%')
pdf.image(f'{WORKSPACE}/creative_2.png', width=5)
pdf.caption('Figure 2: Forest Boots — CTR 1.92%')
pdf.build()
Do NOT import requests/urllib from inside your code — network is blocked and the call will fail with DNS errors. The attachment_url mechanism is the supported path. Extensions (.jpg/.png/.webp/.gif etc.) are auto-detected.
pdf.build() — it must be called last to finalize the PDF.pdf.hr() after headings — gives visual structure.height to images — only width. Height auto-scales.\n for spacing — use separate pdf.body() calls or pdf.spacer().pypdf — it is NOT available. Use marble_pdf only. There is no PDF reading/editing library — regenerate from data instead.from marble_pdf import PDF

pdf.build()
result = {"title": "B&M Performance Report", "description": "Multi-page PDF with cover and recommendations."}
build() saves an HTML file alongside the PDF (e.g., report.pdf.html). To edit, load the HTML, modify it, and re-convert — no need to rewrite the full generation code.
from marble_pdf import html_to_pdf
# Load the saved HTML
with open(f'{WORKSPACE}/report.pdf.html', 'r') as f:
html = f.read()
# Make targeted edits
html = html.replace('Total spend was <b>$793.95</b>', 'Total spend was <b>$850.00</b>')
html = html.replace('0.70x', '0.75x')
# Re-convert to PDF
html_to_pdf(html, f'{WORKSPACE}/report.pdf')
result = {"title": "Updated Report", "description": "Fixed spend and ROAS figures"}
