[英]Undefined method size in PRAWN rails 3
Hi i'm getting error in this line of code: 嗨,我在这行代码中遇到错误:
pdf.font.size = 13
The name of the file is "show.pdf.prawn" 该文件的名称是“ show.pdf.prawn”
I'm trying to generate a page into pdf using the prawn gem. 我正在尝试使用大虾宝石将页面生成为pdf。
But changing the font size isn't working. 但是更改字体大小不起作用。
Any alternatives or workaround? 有其他选择或解决方法吗? Thanks.
谢谢。
BTW: I'm following a simple tutorial from railstips.org : http://railstips.org/blog/archives/2008/10/13/how-to-generate-pdfs-in-rails-with-prawn/ 顺便说一句:我正在跟踪railstips.org上的一个简单教程: http: //railstips.org/blog/archives/2008/10/13/how-to-generate-pdfs-in-rails-with-prawn/
Your tutorial seems to be a little bit old. 您的教程似乎有些陈旧。 You should have a look at this manual : http://prawn.majesticseacreature.com/manual.pdf and/or check the railscasts episode : http://railscasts.com/episodes/153-pdfs-with-prawn-revised .
您应该看一下本手册: http ://prawn.majesticseacreature.com/manual.pdf和/或查看railscasts集: http ://railscasts.com/episodes/153-pdfs-with-prawn-revised。
You can use the font_size
property to define the size of your text like this : 您可以使用
font_size
属性来定义文本大小,如下所示:
font_size(25) { text "Even bigger!" }
You can also do it like this : 您也可以这样:
text "Single line on 20 using the :size option.", :size => 20
Or you can use a block to apply different font properties to your text : 或者,您可以使用块将不同的字体属性应用于文本:
font("Courier", :size => 10) do
text "Yeah, using Courier 10 courtesy of the font method."
