PDFkit hangs when generating a pdf with an image

问题 I want to render a webpage as a PDF. It uses a single image, and I've read that you need to supply the absolute URL for PDFkit to be able to use the image, so my code is: = image_tag image_url(user.avatar) This works when viewed as HTML, and PDFkit is able to generate a PDF with the image removed. However, when using the image, it just hangs until I kill the server. How can I get this to work? Here's the full output when I kill the server: 2013-12-04 13:53:36.576 wkhtmltopdf[27410:507]

问题 Is it possible to display the Euro symbol in pdfkit for nodejs without having to embed an external font?

Background After reading around it seemed to me that Prawn is out and wkhtmltopdf is in. It also seems like the PDFKit and wicked_pdf gems for Rails are the new cool. So I found a screencast by Ryan on how to use PDFKit . I installed everything, tested wkhtmltopdf on the CLI with no problems, fiddled around with Rails settingsto run multiple processes so the asset pipeline works, and all seemed good, except I'm still stuck at the very end of the process (actually getting the PDF response from the server). Question When I request a .pdf version of my view (I'm using the PDFKit Middleware option

问题 I would like to concatenate several PDF files to form one single PDF. Now I've come so far that I know, PDFKit is the proper way to go (I guess). But I am not sure, how to accomplish the merging. Should I have one PDFDocument and several PDFPage and then call insertPage on the PDFDocument ? Or is there a much simpler way? I dont want to alter the PDFs contetwise, I just want to merge them. Thanks a lot! 回答1: As you indicated, you need one output PDFDocument object which will contain all pages

I am generating pdf report from html page with one table . I am using wkhtmltopdf for the purpose. when pdf is generated it breaks anywhere in tr tag . I want to avoid it . Nenotlep Update 17.09.2015: Check the version you are using: wkhtmltopdf 0.12.2.4 is said to fix the problem (I have not checked) . This is a known issue in wkhtmltopdf. The page breaking algorithm used by webkit (the WK in WKhtmltopdf) doesn't really work well for large tables. I suggest breaking the table down to smaller chunks that are more easily split to pages and using the css a lot: table, tr, td, th, tbody, thead,
