I am using reportlab to generate a pdf report automatically from dynamic data. As the content sometimes is too large to be displayed in portrait, I am trying to switch to landscape for large content.

Here is how my report generation works :

Main function :

doc = DocTemplate(...)           //Doctemplate is a customed BaseDocTemplate class
array = []
some_data= "Here is some data displayed in portrait" 


large_data = "this data is too large to be displayed in portrait"

... // Some more data is added after this, canvasmaker=NumberedCanvas)

What I am looking for is a way to be able to switch from portrait to landscape at each step, as I don't know the number of pages that will be needed to display it. I am still new to reportlab and even a bit with python, so I do not see how I can use the solutions provided by reportlab (PageTemplates, flowables) properly as I am building the whole document at the end.

Here are my other useful classes for this case :

class DocTemplate(BaseDocTemplate, ):
def __init__(self, filename, **kw):
    apply(BaseDocTemplate.__init__, (self, filename), kw)
    f = Frame(2.6*cm, 2.8*cm, 16*cm, 22.7*cm, id='f')
    pt = PageTemplate('RectPage', [f], onPage=beforeDrawPage, onPageEnd=afterDrawPage)
    //beforeDrawPage and afterDrawPage fill the headers of the page (that also need to be in landscape)

I think I shall add another page template or frame, but I don't see how i can switch from one to the other during the data appending phase.

class NumberedCanvas(canvas.Canvas):
def __init__(self, *args, **kwargs):
    canvas.Canvas.__init__(self, *args, **kwargs)

    self._saved_page_states = []

def showPage(self):

def save(self):
    """add page info to each page (page x of y)"""
    num_pages = len(self._saved_page_states)
    for state in self._saved_page_states:
    self._doc.SaveToFile(self._filename, self)

def draw_page_number(self, page_count):
    self.setFont("Helvetica", 11)
    self.drawRightString(18.5*cm, 26.8*cm,
        "PAGE %d / %d" % (self._pageNumber, page_count))

I hope I did'nt forgot anything to be clear.

Many thanks in advance.

Use the landscape and portrait functions that are already in the pagesizes module.

from reportlab.lib.pagesizes import letter, landscape
c = canvas.Canvas(file, pagesize=landscape(letter))

How do you change from Landscape to Portrait , Here is a hack, based on the answer I found here. from reportlab.lib.enums import TA_LEFT, TA_RIGHT, TA_CENTER, TA_JUSTIFY from reportlab.lib import​  I think this is because the values returned by the e.g. doc.width methods are not changing as I change the pagesize in the pagetemplate. Can someone put me on the right tracks here? landscape reportlab portrait platypus

I finally figured out the best way to do it by myself :

I added a new PageTemplate in my DocTemplate with landscape settings, and then simply used NextPageTemplate from the reportlab.platypus package :


To get back in portrait, i use :

This is how I switch between portrait and landscape modes, but I determine which orientation beforehand:

from reportlab.lib.pagesizes import letter, A4

lWidth, lHeight = letter

if orientation == 'landscape':
    canvas.setPageSize((lHeight, lWidth))
    canvas.setPageSize((lWidth, lHeight))

All I am trying to do is switch from landscape to portrait orientation in the same document. The other way to set landscape is just set the page size explicitly: from reportlab.lib.pagesizes import landscape from reportlab.pdfgen import canvas from reportlab.lib.units import inch self.c = canvas self.c.setPageSize( (11*inch, 8.5*inch) ) You could make this more generic by doing something like this though:

doc=SimpleDocTemplate(..., pagesize=(A4[1],A4[0]))
