prose <<~TEXT
Stamps should be used when you have content that will be included
multiple times in a document. Its advantages over creating the content
anew each time are:
TEXT
ordered_list(
'Faster document creation',
'Smaller final document',
'Faster display on subsequent displays of the repeated element because ' \
'the viewer application can cache the rendered results',
)
prose <<~TEXT
The <code>create_stamp</code> method does just what it says. Pass it a
block with the content that should be generated and the stamp will be
created.
There are two methods to render the stamp on a page <code>stamp</code>
and <code>stamp_at</code>. The first will render the stamp as is while
the second accepts a point to serve as an offset to the stamp content.

example do
create_stamp('approved') do
rotate(30, origin: [-5, -5]) do
stroke_color 'FF3333'
stroke_ellipse [0, 0], 29, 15
stroke_color '000000'
fill_color '993333'
font('Times-Roman') do
draw_text 'Approved', at: [-23, -3]
end
fill_color '000000'
