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:

parts = []
part = ''
words = line.split()
for word in words:

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()
