[reportlab-users] How to change margins from page to page

[Paul Keating]

What you want to do means that your document is no longer "simple".

To achieve different page layouts you need to up two page templates that define the margins. That's not hard:

FirstPageTextFrame = Frame( ...dimensons... )
StatementFirstPage = PageTemplate (id='Page 1', frames=[FirstPageTextFrame], onPage=FirstPageStatic)

where FirstPageStatic is the function that sets up your fixed header and footer.

OtherPageTextFrame = Frame( ...dimensons... )
StatementFirstPage = PageTemplate (id='Page N', frames=[OtherPageTextFrame], onPage=OtherPageStatic)

Once you've done that you can use a BaseDocTemplate instead of a SimpleDocTemplate:

doc = BaseDocTemplate(filename, pageTemplates=[StatementFirstPage, StatementOtherPage])

Then the first thing you put in your Story is an indication that all pages beyond the first use the alternate page template:

Story = []
Story.append(NextPageTemplate('Page N'))
Story.append( ...flowable... )
etc

I think I'm correct in saying that you really are using a Frame, it's just a default one.

Subject: [reportlab-users] How to change margins from page to page

Hi,
I have a case where the first page of a document has two inches worth of fixed header information and another 4 inches of data on the bottom of the document that is taken up with a check. The middle 3 or 4 inches on the first page is for dynamic flowable stuff, like a table and some paragraphs. The first page works great.
I am using a bottom margin of 4 inches for it. However, I don't need to have a bottom margin on any pages past the first page. How do I change the margins for the rest of the document?
I tried adding this to my later pages method:

doc.bottomMargin = 0.5 * inch
But that doesn't have any effect. I also saw this post from a few years ago:

But I'm not using Frames. Does anyone have any insights? I am using a SimpleDocTemplate. Thanks!
