Optional callback function for each page in PDF.

[vb64]

The following arguments are passed to the function:

• Current section
• Page number within the current section
• Page number from the beginning of the PDF document

Hi, i am interessed on this feature, and more generrally to have the ability to put a footer with something as {current_page}/{total_page}. Is this a way to do?

When I have more free time for this.

You can try to implement this functionality by yourself and prepare a PR.

How I see the interface.

pdf = MarkdownPdf()
assert pdf.page_functions == []
pdf.page_functions.append(page_func)

each page_func from pdf.page_functions must be called twice when each page is rendered.

first time when the page is newly created and empty.

second time when the relevant markdown content is rendered on the page.

each time page_func is called the following arguments are passed

def page_func(
  canvas,  # PyMuPDF canvas for drawing
  pdf,  # markdown_pdf.MarkdownPdf instance
  pdf_page_number,  # Page number from the beginning of the PDF document
  section,  # Current markdown_pdf.Section 
  section_page_number,  # Page number from the beginning of the current section
  is_on_start  # True, if function called first time on the page
):

I will take a look to this (when i will get the time XD)
