用大虾加水印（使用模板）
|
我需要能够为从模板创建的文档添加水印。我现在有以下代码：
# Note: the raw PDF text (body variable below) is sent from a remote server.
Prawn::Document.new(:template => StringIO.new(body), :page_size =>
\'A4\') do |document|
# ... including other pages and sections to the template here ...
# watermark
d.page_count.times do |i|
d.go_to_page i
d.stroke_line [d.bounds.left, d.bounds.bottom], [d.bounds.right, d.bounds.top]
d.draw_text \"Watermark\", :rotate => 45, :at => [100,100], :size => 100
end
end
PdfStamper stamper = new PdfStamper(...);
PdfContentByte over = stamper.GetOverContent(i + 1);
over.BeginText();
over.SetTextMatrix(20, 40);
over.SetFontAndSize(bf, 20);
over.SetColorFill(new Color(97, 150, 58));
over.ShowTextAligned(Element.ALIGN_CENTER,
watermarkText,
document.PageSize.Width / 2,
document.PageSize.Height / 2,
55);
over.EndText();
over.Stroke();
:template
StringIO
#add_content

create_stamp(\"watermark\") 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 \"Watermark\", :at => [-23, -3] end fill_color \"000000\" end end stamp_at \"watermark\", [210, 210]柑恫祟
create_stamp(\"stamp\") do fill_color \"cc0000\" text_rendering_mode(:fill_stroke) do transparent(0.5){ text_box \"WATERMARK\", :size => 50, :width => bounds.width, :height => bounds.height, :align => :center, :valign => :center, :at => [0, bounds.height], :rotate => 45, :rotate_around => :center } end end repeat (:all) do stamp(\"stamp\") end
