Function to draw text with proper formatting

def draw_text(text, x, y, font_size=12, max_width=500): c.setFont("Helvetica", font_size) lines = text.split("\n") y_position = y for line in lines: if c.stringWidth(line, "Helvetica", font_size) > max_width: parts = [] part = '' words = line.split() for word in words: if c.stringWidth(part + ' ' + word, "Helvetica", font_size) <= max_width: part += ' ' + word else: parts.append(part) part = word if part: parts.append(part) for part in parts: c.drawString(x, y_position, part.strip()) y_position -= 1.2 * font_size else: c.drawString(x, y_position, line.strip()) y_position -= 1.2 * font_size

Iterate through slides and draw content to PDF

for slide in prs.slides: for shape in slide.shapes: if hasattr(shape, "text"): if shape.has_text_frame: text_frame = shape.text_frame paragraphs = text_frame.paragraphs for paragraph in paragraphs: text = paragraph.text draw_text(text, 50, 750) # Adjust position as needed

c.showPage()

c.save()
