Edit

Fixed in 0.12.5 - Please update to this version.

!! Note that downgrading openssl is not a solution !!

Original issue

Ubuntu Ubuntu 14.04.4 LTS

Loading pages (1/6)
QSslSocket: cannot resolve SSLv3_client_method               ] 10%
QSslSocket: cannot resolve SSLv3_server_method

I have libssl-dev and openssl installed.

wkhtmltopdf --version
wkhtmltopdf 0.12.3 (with patched qt)

Hi,

Rendering a page with JPG images crashes on Windows Server 2008 in step 6. It works on Windows 8. I believe this only occurs on websites that use JPG images.

For instance this works:

wkhtmltopdf.exe "http://www.google.com" test.pdf

But this doesn't:

wkhtmltopdf.exe "http://news.bbc.co.uk" test.pdf

I believe it is the same issue as this: https://code.google.com/p/wkhtmltopdf/issues/detail?id=301

Rendering a completely blank HTML file on OS X:

• 0.12.1 generates a 4 KB file
• 0.10.0 RC2 generates a 1 KB file

Pages with more HTML see a similar ratio:

• 0.12.1 generates a 648 KB file
• 0.10.0 RC2 generates a 111 KB file

This is a comparison between the output created by the Mac OS X version of 0.12.3 and 0.12.4 - I consider what I see with 0.12.3 the correct output.

I am running the software on Mac OS X 10.11.6

This test was done using these builds downloaded from the official web site:

wkhtmltox-0.12.3_osx-cocoa-x86-64.pkg wkhtmltox-0.12.4_osx-cocoa-x86-64.pkg

I use a very simple HTML file that only contains a few headers from h1 to h3 plus some lorem ipsum sample text in p tags.

The HTML file was converted using no command line options besides the input and the output file:

wkhtmltopdf test.html test.pdf

Here is the sample HTML file (renamed to .txt to be able to attach it): test.txt

And here are the two output files created by the two different wkhtmltopdf versions: test_0.12.3.pdf test_0.12.4.pdf

The paragraph text in the 0.12.3 version if about 12.3pt in size, whereas the 0.12.4 version creates 3.07pt text. It seems that all text is by a factor of 4 too small.

This may be related to the other "font size is too small" problems, but what I am seeing seems to be much more extreme than anything else I've found so far.

I would like to compile wkhtmltox 0.12.1 on my OpenBSD 5.5 machine but unfortunately it already fails while running "./scripts/build.py posix-local" as you can see below:

any ideas what I am missing or whats wrong?

This is the old Issue #72 from Google Code, first reported in 2009. It still occurs with the dev branch of 0.12.0, tested with commit d6541feaaa8253516c92faae34293430efeb070a .

What steps will reproduce the problem?

1. Generate PDF from any HTML input with wkhtmltopdf via e.g.

   ./wkhtmltopdf test.html test.pdf
   

2. View it. Tested with Evince, Xpdf and Chrome's built-in PDF reader with similar results.

What is the expected output? What do you see instead? Expected: A PDF rendering similar to the one seen of the HTML document in a browser, specifically concerning the letter-spacing.

Result: The kerning is way off. Sometimes too expanded, sometimes too condensed. See attached sample rendering of (from left to right):

1. an HTML document rendered by a browser (Chrome)
2. the resulting PDF rendered by Chrome's built-in PDF reader
3. the resulting PDF rendered by Evince

What version of the product are you using? On what operating system? Dev branch of 0.12.0, tested with commit d6541feaaa8253516c92faae34293430efeb070a . Debian Sid, i386. Using the binary that resulted after building the Git revision with:

./build_linux.sh linux-i386

I have tested earlier versions of Wkhtmlpdf on Fedora (amd64) with identical results.

Please provide any additional information below. I include the sample document and rendering below, but it happens with everything I throw to Wkhtmltopdf, so I don't think there are any specific "clues" in the minimal HTML code.

• Generated PDF (semi-stable host)
• Direct link to HTML document (semi-stable host)
• HTML document at Pastebin
• Screenshot of rendering. Best viewed in full size. Note e.g. the whitespace after the letter "o" in the PDF renderings.
• Full strace output
• strace output, grep:ed for file I/O

Ignore the following untracked files which are generated during the MSVC build:

# HEAD detached at 924bcb7

(Sorry for the snipping of the host, but it's internal anyway and a bit private) Might be a continuation from #1713, dunno.

Flexbox seems to be broken in wkhtmltopdf.

Here's a test case, which renders correctly in current versions of Chrome, Firefox, and Internet Explorer. wkhtmltopdf renders it as if the flex properties were not present.

Tested with the 0.12 Windows 32-bit download as found on http://wkhtmltopdf.org/ (wkhtmltox-win32_0.12.0-03c001d.exe). As you can see I tried using the -webkit- prefixes and they didn't help.

Hello !

My company (a LMS) is using your tool to generate certificates for our learners. The support was not able to explain me some limitation of the tool so I try with you :-)

Today, our certificate generator is not willing to export text in white or light colors, it always set up a darker colour when it create the PDF. For example, if I write #ffffff or #fafafa in my code, it will render a #8A8A8A grey. Have you heard about this limitation ? Do you face the same or it’s juste the way our IT set up your tool?

Thank you, have a wonderful day ! Marianneski

I've already created the one ticket in SO Link

I'm not able to execute the --allow command in wkhtmltopdf any suggestion about this? or did I miss something?

I'm using the wkhtmltopdf for creating HTML to pdf it's working fine but for some additional requirements in the pdf, I have to add the background image/watermark on every page.

I go through this link wkhtmltopdf they mention a few commands below

--allow <path> Allow the file or files from the specified folder to be loaded (repeatable) --background Do print background (default)

Is there any sequence issue in the below command argument? Here is my command argument.

--page-size A4 --footer-html http://localhost:49955/PDFExport/FooterUrl --footer-left "Printed On 11/6/2022" --footer-right "Page [page] of [topage]" --footer-font-size "7" --header-spacing 5 --margin-top 5mm --margin-left 0mm --margin-right 0mm --outline-depth 4 --background http://localhost:49955/PDFExport/BackgroundURL --enable-local-file-access --allow "F:\bg-overlay.jpg" "https://wkhtmltopdf.org/usage/wkhtmltopdf.txt" "F:\TestBackground.pdf"

Here you can see how PDF looks -> OutPut link

I'm not able to perform the below command let me know what I missed in the command.

--background --enable-local-file-access --allow

I've already raised the ticket related to c# but I'm eagerly know that how we can run into command line -> https://github.com/codaxy/wkhtmltopdf/issues/34#issue-1268239325
