我需要把2圖像和文字在同一行。標題與蝦欄
例如:
(圖像1) 「TEXT」(圖像2)
模擬的報頭。 這裏是我的代碼:
class PruebasPdf < Prawn::Document
def initialize(prueba)
super()
@prueba = Prueba.order("id DESC").all
cabecera
prueba_id
marcagua
end
def cabecera
image "#{Rails.root}/app/assets/images/logo-i.jpg", :width => 50, :height => 50,:position => :left
text "Universidad Centroccidental Lisandro Alvarado", size: 18, style: :bold, align: :center
image "#{Rails.root}/app/assets/images/logo-d.jpg", :width => 50, :height => 50,:position => :right
end
def prueba_id
table prueba_id_all do
row(0).font_style = :bold
columns(1..3).align = :center
self.row_colors = ["DDDDDD","FFFFFF"]
self.header = true
end
end
def prueba_id_all
[["Titulo","Descripcion","Fecha"]] +
@prueba.map do |prueba|
[prueba.titulo,prueba.desc,prueba.fecha]
end
end
def marcagua
create_stamp("watermark") do
rotate(30, :origin => [-5, -5]) do
stroke_color "FF3333"
stroke_color "000000"
fill_color "993333"
font("Times-Roman") do
draw_text "Coordinacion de Investigacion", :at => [-23, -3]
end
fill_color "000000"
end
end
stamp_at "watermark", [300, 300]
end end
有誰知道它是如何做到的?提前致謝! 對不起我的英語---
