Absolutely! You can absolutely add rotated or vertical text in your PDF using PyFPDF—turns out it does support this, even if it’s not immediately obvious. Let me walk you through a few approaches, plus alternatives if you need more flexibility.

PyFPDF has built-in support for rotating text via coordinate transformations. Here’s how to implement it:

1. Rotate Text at a Specific Position #

Use the rotate() method to set a rotation angle, draw your text, then reset the rotation to avoid affecting subsequent content. This works perfectly for vertical text (rotated 90 or 270 degrees):

from fpdf import FPDF

pdf = FPDF()
pdf.add_page()
pdf.set_font("Arial", size=12)

# Rotate 90 degrees clockwise around (x=10, y=50)
pdf.rotate(90, x=10, y=50)
pdf.text(x=10, y=50, txt="Vertical Text (Rotated 90°)")
pdf.rotate(0)  # Reset rotation to default

# Rotate -90 degrees (270° clockwise) for the opposite vertical direction
pdf.rotate(-90, x=190, y=50)
pdf.text(x=190, y=50, txt="Vertical Text (Rotated -90°)")
pdf.rotate(0)

# Add regular text for comparison
pdf.text(x=50, y=50, txt="Regular Horizontal Text")

pdf.output("rotated_text.pdf")

Note: The rotate() method takes the rotation angle (in degrees) and the origin point (x, y) around which the text will rotate. Always reset the rotation to 0 after drawing your rotated text—otherwise all future content will inherit the rotation.

If you need more flexibility (like wrapped rotated text or complex layouts), these Python libraries are excellent options:

1. ReportLab #

ReportLab is a robust PDF generation tool with intuitive rotated text support:

from reportlab.pdfgen import canvas

c = canvas.Canvas("reportlab_rotated.pdf")
c.setFont("Arial", 12)

# Draw vertical text (90 degrees rotation)
c.saveState()
c.rotate(90)
c.drawString(50, -100, "Vertical Text with ReportLab")
c.restoreState()

# Add regular horizontal text
c.drawString(50, 100, "Regular Horizontal Text")

c.save()

2. PyMuPDF (fitz) #

PyMuPDF is great for both creating new PDFs and modifying existing ones, with straightforward rotated text insertion:

import fitz

doc = fitz.open()
page = doc.new_page()

# Insert vertical text (90 degrees rotation)
page.insert_text((10, 50), "Vertical Text with PyMuPDF", fontsize=12, rotate=90)

# Insert regular text
page.insert_text((50, 50), "Regular Horizontal Text", fontsize=12)

doc.save("pymupdf_rotated.pdf")

You don’t need to switch to PHP’s FPDF—PyFPDF fully supports rotated/vertical text using its rotate() method. For more advanced use cases, ReportLab or PyMuPDF offer even more flexibility to handle complex text layouts.
