Does Wicked PDF supports embeding images? #36
Comments
|
images work just fine. Wkthmltopdf needs to know the full path to the file to be able to render it internally. So, image_tag('foo.jpg') won't work because it outputs a relative path and wk needs to know where /images is. The library mixes in helpers for images, stylesheets, and javascripts. So, wicked_pdf_image_tag('foo.jpg'), will output <img src="file:///home/users/emzero/cool_app/public/images/foo.jpg"> An alternative way is to point to a remote server image, like so: image_tag("http://yourserver.com/images/foo.jpg") |

i'm having this problem on heroku cedar stack. works perfectly fine on local env. here are the gems i am using: File uploadgem 'paperclip', '~> 2.4' Creating PDFsgem 'wicked_pdf' Maybe you have suggestions or possible solution i can start with. Thanks |
|
@ademar11 Use :show_as_html => true in your pdf generation and check that the img src's are correct. |
|
@unixmonkey, i tried doing this: rendered_invoice = render_to_string(:template => "invoices/pdf/pdf_invoice.pdf.haml", :layout => "layouts/pdf", :show_as_html => true )
pdf = WickedPdf.new.pdf_from_string rendered_invoice
File.open(save_path, 'wb') do |file|
file << pdf
endWhen i open the file, the image attached is still not saved. Although, if I view it on browser and not saving it as a pdf the images appear. |

@unixmonkey nope not using wicked_pdf_image_tag, but it works on rendering the pdf on view. the problem is just when we save it into a file, as specified in the code above (#36 (comment)) Maybe this is a pdf_from_string method error? This did not work also: :show_as_html => true |

this is the same issue I am having with the latest version, using a cloud storage for my images. Has anyone figured out a work-around for this? |
|
@numsweb You can use the full url for the assets stored on the cloud: https://s3.amazonaws.com/my-bucket/foo.pngIs that what you are asking? |

I would suggest you capture the output of Image tags need to look like this: Not like this: Does that make sense? You may want to try using |

I'm sorry, but I don't see an image, nor a URL to it, nor the HTML generated from your calling "render". Please provide that and I can be more helpful. |

@numsweb I'm guessing you think that I can see or inspect anything that you are attaching to your emails. I cannot. |

Hey unixmonkey, I tried image_tag(@receipt.image_link) none of them seem to work. Thanks |
|
@qpham415 What do the links stored in your database look like, and where are the files actually stored? If they are full URI's, they should work, if they are not, then you'll want to construct the string to them appropriately. For instance if
The leading slash tells rails to look under "public" instead of the asset pipeline. This should also work, and should be faster since it would load from disk instead of over HTTP:
|
|
Thanks for the quick reply. The links stored in the database are full URIs from external site It's weird, I am able to display the image on my show page with image_tag but when I go to generate the pdf, it's a blank box. |

This sounds like a recent HTTPS issue I've seen. You can try to update to the latest app/helpers/application_helper.rb require 'open-uri'
def embed_remote_image(url, content_type)
asset = open(url, "r:UTF-8") { |f| f.read }
base64 = Base64.encode64(asset.to_s).gsub(/\s+/, "")
"data:#{content_type};base64,#{Rack::Utils.escape(base64)}"
endapp/views/receipts/show.pdf.erb <%= image_tag embed_remote_image(@receipt.image_link, 'image/png' ) %> |

Your solution works perfectly, thanks for all your help! I will try updating wkhtmltopdf later also. |

@Murali-Mohan-M Do you have jQuery or JsBarcode loaded? |

Hello Guys, If any body want to add image with in the pdf then please follow https://github.com/ashishprajapati/add_image_inside_pdf |

Hello, Thank you for your great work, it works pretty well with Rails application. Loading images into PDF works well too, except when the file name of those images contain Chinese marks. Actually it works well too in development environment, but not in production environment. Any suggestions how this issue should be handled? Thanks in advance. |
|
@lyonsun I wonder if that has something to do with not having Chinese character sets installed on your production server or something like that, or if it's just a coincidence, and there's something else going on with HTTPS or network routing. I don't have any great suggestions to troubleshoot this, except to maybe to proxy them to local files as described above in this issue here. |
|
@unixmonkey Thank you for your quick response.
Images are stored on local disks of the production server rather than the cloud, and the problem is that the filename of these images contains Chinese characters. |
|
@unixmonkey I just managed to solve the problem using the alternative way you suggested here to point to the image with full URL. Exact code for image display in view file:

Hi,
Great work you've done with Wicked PDF.
I'm wondering if it supports adding images. I've tried dropping some![]()
tags but I'm getting blank boxes, so it seems it recognizes the image tags, but is not capable of embeding them into the PDF.
Is that being supported? If so, how exactly I can achieve?
Thank you.
