Changing margins

To change the margins of a page you need to set them before the `add_page` method or you won’t see the changes.

You can set the margins using different methods: `set_margins()`, `set_left_margin()`, `set_top_margin()`, `set_right_margin()` but I prefer to use the margin variables directly: `l_margin`, `r_margin`, `t_margin`, `b_margin`. Is less verbose, concise and gives me more control.

# Import FPDF class
from fpdf import FPDF

# Create instance of FPDF class

# Set margins BEFORE add_page!
# Margin sizes multiples of default size
pdf.l_margin = pdf.l_margin*4.0
pdf.r_margin = pdf.r_margin*4.0
pdf.t_margin = pdf.t_margin*4.0
pdf.b_margin = pdf.b_margin*4.0

# Now we add a page. It is in this step that margins settings take effect.

# Effective page width and height
epw = pdf.w - pdf.l_margin - pdf.r_margin
eph = pdf.h - pdf.t_margin - pdf.b_margin

# Draw new margins.
pdf.rect(pdf.l_margin, pdf.t_margin, w=epw, h=eph)

# Remember to put at least one of this font declarations when you are going
# to render text.  Not needed if not drawing text.

# Text height
th = pdf.font_size

# Draw margin sizes.
# Need this line break, otherwise top line crosses text. Still have not
# figure that one out but it has to do with how text is positioned with
# respect x and y coordinates.


pdf.cell(epw,0, 'Left: %s in, Right: %s in, Top: %s in, Bottom: %s in' % \
(pdf.l_margin, pdf.r_margin, pdf.t_margin, pdf.b_margin))
