page layout ignored when generating pdf from template pdf
This is a prawnpdf/prawn#293. I ran into this issue and figured out the cause and a workaround that I'm using via monkey patching. I'm posting my analysis of the bug here since apparently there's an attempt to revive the templates code.
The problem lives in PDF::Core::Page. Basically when templates are used, the size instance variable does not get set, so calls to page.size just return the dimensions. However, when this value is fed back into Page.new to create a new page, it reverses the coordinates if the layout is landscape. Since page.size already gives you the coordinates in landscape, reversing them makes it portrait. The below change to the method ensures that the size method always returns coordinates as if the layout was portrait
module PDF
module Core
class Page
def size
return @size if defined?(@size) && @size
case(layout)
when :portrait
dimensions[2,2]
when :landscape
dimensions[2,2].reverse
end
end
end
end
end
This would be tricky to fix for real since it's in pdf core, but it might represent a legitimate bug there too.
Version 0.1.2 messing up (cross-OS) rendering
After updating we started seeing our PDFs (UNIX-generated) stopped working in Windows machines. Apparently a font issue, but we did nothing other than update the gem version...
See Expected and Result pictures attached (details blurred out purposefully).
Still maintained?
@pointlessone Is this repo still maintained as part of the prawnpdf set? Should I get it working with GitHub Actions, prawn-dev, etc?
Redefine PDF::Core methods without causing a warning
There are ways in Ruby to override a method without generating a warning. Please consider using one of those approaches to override the methods in PDF::Core. This will avoid the following warnings:
../gems/prawn-templates-0.0.5/lib/pdf/core/document_state.rb:4: warning: method redefined; discarding old initialize
../gems/pdf-core-0.7.0/lib/pdf/core/document_state.rb:4: warning: previous definition of initialize was here
../gems/prawn-templates-0.0.5/lib/pdf/core/object_store.rb:4: warning: method redefined; discarding old initialize
../gems/pdf-core-0.7.0/lib/pdf/core/object_store.rb:16: warning: previous definition of initialize was here
../gems/prawn-templates-0.0.5/lib/pdf/core/page.rb:4: warning: method redefined; discarding old initialize
../gems/pdf-core-0.7.0/lib/pdf/core/page.rb:24: warning: previous definition of initialize was here
../gems/prawn-templates-0.0.5/lib/pdf/core/page.rb:43: warning: method redefined; discarding old dimensions
../gems/pdf-core-0.7.0/lib/pdf/core/page.rb:150: warning: previous definition of dimensions was here
Here are some strategies:
remove the method before redefining it(see https://github.com/asciidoctor/asciidoctor-pdf/blob/579029559cb55afea7f5c30ee47cf69cd85913ed/lib/asciidoctor-pdf/prawn-table_ext/cell/text.rb)- alias the method before redefining it (e.g.,
alias :__initialize :initialize)- oddly, this suppresses the warning
- prepend the methods from a module (see https://github.com/asciidoctor/asciidoctor-pdf/blob/579029559cb55afea7f5c30ee47cf69cd85913ed/lib/asciidoctor-pdf/prawn_ext/formatted_text/fragment.rb)
Is it possible to render content behind the template page?
I need to render an image behind the content from the template. Is that possible?
It would be nice to have 0.0.4 on rubygems.org
Releases still not being published on rubygems
it looks like permission to push to rubygems has been granted, but the published version is still at 0.3
It would be nice to have 0.5 on rubygems!
Prawn content is vertically mirrored for PDFs exported by Google Chrome
I've collected the following links that demonstrate the problem:
- prawnpdf/prawn#568
- prawnpdf/prawn#393
- https://stackoverflow.com/questions/12076299/my-text-is-written-in-a-bad-direction-when-i-use-a-template
There's also a very comprehensive StackOverflow answer that might explain what's going on.

This is a critical issue for my app, so I will attempt to fix it myself. I'll submit a PR if I manage to solve the problem. Any assistance would be greatly appreciated!

Since prawn-template tries to append to the, now frozen, Prawn::Document::VALID_OPTIONS array.
