A multiline(paragraph) footer and header in reportlab

What is a best way to have a footer and header in reportlab, that not just a single line, that can be drawed with canvas.drawString in onPage function. Didn`t find a way to put something like Paragraph into header/footer in onPage function. What is the best way to handle this? Is there a way to put a paragraph into footer ?


You can use arbitrary drawing commands in the onPage function, so you can just draw a paragraph (see section 5.3 in the reportlab user guide) from your function.

Here is a complete example:

from reportlab.lib.pagesizes import letter
from reportlab.lib.styles import getSampleStyleSheet
from reportlab.platypus import BaseDocTemplate, Frame, PageTemplate, Paragraph

styles = getSampleStyleSheet()
styleN = styles['Normal']
styleH = styles['Heading1']

def footer(canvas, doc):
    P = Paragraph("This is a multi-line footer.  It goes on every page.  " * 5,
    w, h = P.wrap(doc.width, doc.bottomMargin)
    P.drawOn(canvas, doc.leftMargin, h)

doc = BaseDocTemplate('test.pdf', pagesize=letter)
frame = Frame(doc.leftMargin, doc.bottomMargin, doc.width, doc.height,
template = PageTemplate(id='test', frames=frame, onPage=footer)

text = []
for i in range(111):
    text.append(Paragraph("This is line %d." % i,
