Debugging Prawn reached end of graphics state stack
prawn, ruby-on-rails
Solution
You have a repeater which is applied to every page, and whose content is more than one page wide. That's what Prawn is telling you with that not very self-explaining error.
Now, from the stacktrace the error comes from `write_header` call. It seems your bounding box on that method has a fixed height (`28`) and it's content is higher: two lines and the `move down 8`.
Try extending bounding_box's height or making it's content shorter.
Problem
``` class Report attr_reader :pdf def to_pdf Prawn::Document.new(page_layout: page_layout) do |pdf| @pdf = pdf pdf.repeat(:all) do frame_page end pdf.repeat(:all) do write_header end #write_section_divider puts "wrote the header" #this is not getting hit write_body ``` In my subclass: ``` def write_header puts "Writing header" pdf.move_down 8 pdf.text title, size: 22, style: :bold, align: :center puts "wrote title" pdf.bounding_box([0, pdf.cursor], width: pdf.bounds.right, height: 28) do puts "bounding box" pdf.move_down 8 pdf.text date_title, size: 16, align: :center pdf.text current_day_title, size: 16, align: :center puts "moved down" end puts "exited bounding box" end F, [2015-02-23T02:18:30.106303 #6] FATAL -- : 2015-02-23T02:18:30.106684+00:00 app[web.1]: app/reports/report.rb:6:in `to_pdf' 2015-02-23T02:18:30.106680+00:00 app[web.1]: app/reports/report.rb:13:in `block in to_pdf' 2015-02-23T02:18:30.106682+00:00 app[web.1]: app/reports/report.rb:6:in `new' 2015-02-23T02:18:30.106674+00:00 app[web.1]: Prawn::Errors::EmptyGraphicStateStack ( 2015-02-23T02:18:30.106677+00:00 app[web.1]: You have reached the end of the graphic state stack): 2015-02-23T02:18:30.106690+00:00 app[web.1]: 2015-02-23T02:18:30.106691+00:00 app[web.1]: 2015-02-23T02:18:30.106688+00:00 app[web.1]: app/controllers/verified_return_money_reports_controller.rb:21:in `create' 2015-02-23T02:18:30.106687+00:00 app[web.1]: app/reports/verified_return_money_report.rb:6:in `to_pdf' ``` Why is my Prawn drawing failing?
