问题 I want to simulate the behaviour of a table in Prawn, but can't use table because of the limitation of things I can draw inside cells. So I am using bounding boxes in order to create contexts for the elements inside each row. The problem I'm having has to do with the rows. I'm trying this: require 'prawn' Prawn::Document.generate("test.pdf") do move_down 50 bounding_box [0, cursor], width: bounds.width do 20.times do |i| stroke_bounds && start_new_page if (i+1) % 11 == 0 bounding_box [0,

Any font for generating pdf that will handle Chinese, Cyrillic… ?

由 南笙酒味 提交于 2019-12-06 01:39:54
问题 I'm creating generator of pdf documents in Ruby on Rails with Prawn gem and I came up with issue that when I have Chinese, Japanese and Cyrillic chars they are displayed incorrectly. I googled out that it's because "when I'm generating font I need to specify, what font should pdf text be rendered with" . Now this isn't the issue, but the fact that my documents will include all different possible chars that gTLD supports. Question 1: Do you know any font for generating pdf documents that will

Is there any options to customize stroke_bounds? (Rails Prawn)

由 只愿长相守 提交于 2019-12-05 21:05:34
I want to draw borders for all the pages in my PDF. But while using stroke_bounds , I can only draw single dark lined borders alone. I couldn't customize anything? Does anybody have any idea on how to change the style of my stroke_bounds borders? Use dash in Prawn::Graphics::Dash http://prawn.majesticseacreature.com/docs/0.11.1/Prawn/Graphics/Dash.html example: pdf.dash 10, :space => 4 pdf.stroke_bounds Erich I had the same problem. I found out that you can use the "stroke_color" function to change this color. http://prawnpdf.org/docs/0.11.1/Prawn/Graphics/Color.html#method-i-stroke_color
