Ruby Prawn PDF 页眉页脚 checkbox 以及 style
Prawn::Document.generate("#{Rails.root}/../dfs/metadata.pdf",
:info => {
:Title => "My title",
:Author => "John Doe",
:Subject => "My Subject",
:Keywords => "test metadata ruby pdf dry",
:Creator => "ACME Soft App",
:Producer => "Prawn",
:CreationDate => Time.now,
:Grok => "Test Property"
}) do
text "This is a test of setting metadata properties via the info option."
text "It allows one to specify non standard properties like 'Grok'."
end
页脚页眉怎么生成？
prawn 是纯 ruby 代码，可以用 ruby 的各种模块化方式组织，一个简单解决方法是用 load 执行：
load "./pdf_t.pdf.prawn"
Prawn::Document.generate("#{Rails.root}/../dfs/hello.pdf") do
header margin_box.top_left do
text "Here's My Fancy Header", :size => 25, :align => :center
end
text "hello world!"
end
ActionView::Template::Error (undefined method `header' for #Prawn::Document:0x007fb8e000a820):
Prawn::Document.generate('hello.pdf') do
text("Hello Prawn!")
start_new_page
text("Hello Prawn!")
start_new_page
text("Hello Prawn!")
number_pages "<page> in a total of <total>", :start_count_at => 0, :page_filter => :all, :at => [bounds.right - 100, 0], :align => :right, :size => 25
end
Prawn::Document.generate("test.pdf") do
repeat :all do
# header
bounding_box [bounds.left, bounds.top], :width => bounds.width do
#font "Helvetica"
#text "Here's My Fancy Header", :align => :center, :size => 25
data = [
["1","2","3"],
["2","3","4"]
]
table(data)
stroke_horizontal_rule
end
# footer
bounding_box [bounds.left, bounds.bottom + 25], :width => bounds.width do
font "Helvetica"
stroke_horizontal_rule
move_down(5)
text "And here's a sexy footer", :size => 16
end
end
bounding_box([bounds.left, bounds.top - 50], :width => bounds.width, :height => bounds.height - 100) do
text "this is some flowing text " * 400
end
end

多选框 https://gist.github.com/bradediger/58890
# "☐" "\xE2\x98\x90" "\u2610"
# "☑" "\xE2\x98\x91" "\u2611"
# "☒" "\xE2\x98\x92" "\u2612"
# "font" "#{Prawn::BASEDIR}/data/fonts/DejaVuSans.ttf"
def checkbox(label, checked)
box = checked ? "\u2611" : "\u2610"
checkbox_font = "#{Prawn::BASEDIR}/data/fonts/DejaVuSans.ttf"
"<font name='app/assets/fonts/STSONG.TTF'>#{label}</font><font name='"+checkbox_font+"'>"+box+"</font>"
end
font "app/assets/fonts/STSONG.TTF"
# 如有多选框 并且默认字体是仿宋 会报错 bad font 我只能切换到以前的字体，谁有没有更好的方法
font "Helvetica"
table([
[checkbox("读书",true),checkbox("书法",true),checkbox("绘画",false)]
], :cell_style => {:inline_format => true})
