qt's Introduction

wkhtmltopdf and wkhtmltoimage

wkhtmltopdf and wkhtmltoimage are command line tools to render HTML into PDF and various image formats using the QT Webkit rendering engine. These run entirely "headless" and do not require a display or display service.

See https://wkhtmltopdf.org for updated documentation.

Building

wkhtmltopdf has its own dedicated repository for building and packaging.

See https://github.com/wkhtmltopdf/packaging

qt's Issues

Build failure on IBM Z (s390x)

Building wkhtmltopdf with the patched qt on IBM Z (s390x) failed with ld complaining about a missing symbol in qt. Turns out that the implementation of fetchAndAddOrdered is missing in qatomic_s390.h.

Please consider picking up that patch:
https://bugreports.qt.io/browse/QTBUG-23257

With that patch the build was successful. I did run some tests with the resulting wkhtmltopdf binary and it all looked good to me.

Segmentation Fault on blockquotes tag if css specified

@optyler commented on Fri Oct 05 2018

Hi,

we just found a segmentation error while converting a local html which contains a blockquote tag AND with a quotes css property defined on it.

<html xmlns="http://www.w3.org/1999/xhtml">
 <head>
    <title>Test</title>
    <style>
      blockquote {
        quotes: none;
      }
    </style>
 </head>

 <body>

Erreur de segmentation=========>                             ] 50%

If I remove the quotes: none; property, the conversion works fine.

qt_defaultDpi() issue

Could someone explain, what it was? git push --force?
qt_defaultdpi
I've removed repo and cloned again. Looks fine now.

[PATCH] fix for "HTML Input text controls doesn't print the value in PDF"

This little patch fixes:
wkhtmltopdf/wkhtmltopdf#2004
wkhtmltopdf/wkhtmltopdf#2005

There's also a typo "Parrent" vs "Parent" but I don't know if that affects anything ;)

Instructions aren't current with Qt's online docs and source code

I'm trying to follow instructions to install your patched Qt. Finally, I got the separate qt repo into the wkhtmltopdf repo (I probably should have made it a git submodule, but haven't yet). Then I tried:

./build package-docker buster-amd64 ../wkhtmltopdf

and got:

Error: remote trust data does not exist for docker.io/aptman/qus: notary.docker.io does not have trust data for docker.io/aptman/qus
docker pull --platform linux/amd64 aptman/qus:d5.0
command failed: exit code 1

I do not know much about docker and would appreciate knowing how to proceed.

For many years I have enjoyed using wkhtmltopdf on Linux via a screen grab, but being able to script it on a remote host would be wonderful!

Note I am a long-time Perl (since 1993) and now Raku user (since 2015), but I've also had to create or maintain Fortran, C, and C++ libraries for necessary jobs at $work. But it's been over 15 years since I've had to compile Qt and it was NEVER any fun.

Need qt patch for Toc support

i have convert table of content web page to pdf using wkhtmltopdf wrapper with own builded qt source in windows 8.1 in output pdf file internal and external links are not enbled due to that page navigation does not work .and used toc option ( wkhtmltopdf toc Toc.html toctest.pdf) in command i am getting warning "This version of wkhtmltopdf is build against an unpatched version of QT "

Homebrew fatal error: branch wk_4.8.6 not found...

I was trying to follow the first instruction on http://natepinchot.com/2014/01/31/building-static-wkhtmltopdf/ for OS X and Homebrew, which is...

brew install https://raw.github.com/npinchot/homebrew/wkhtmltopdf_static_qt/Library/Formula/qt-wkhtmltopdf.rb

I got the following output...

==> Cloning https://github.com/wkhtmltopdf/qt.git
Cloning into '/Library/Caches/Homebrew/qt-wkhtmltopdf--git'...
warning: Could not find remote branch wk_4.8.6 to clone.
fatal: Remote branch wk_4.8.6 not found in upstream origin
Unexpected end of command stream
Error: Failed to download resource "qt-wkhtmltopdf"
Failure while executing: git clone --depth 1 --branch wk_4.8.6 https://github.com/wkhtmltopdf/qt.git /Library/Caches/Homebrew/qt-wkhtmltopdf--git

Looking here, I see that there is a 4.8.5 branch, but not 4.8.6. Is there a problem that needs to be fixed for this to work? Alternatively, is there a different set of instructions that I should be following to install wkhtmltopdf with static QT via Homebrew?

HTML input fields not fillible

I just updated from 12.3 to 12.4 to fix an issue where fallible fields do not show text when printed. After the update those input fields are no longer fillable, and I have --enable-forms in the CLI. This is a PHP script I am working with. For now I have reverted to the old version so my users are not impacted, but any advice on this would be very appreciated.

Need to add woff font support in wkhtmltopdf

Hi all ,

i have convert html to pdf file using wkhtmltopdf source with qtwebkit 5.3.1 assemblies while using woff font in html file it looks fine in web browser but in pdf it looks like normal font .and getting warning "woff font requires qtwebkit need to build with zlib support " so i again build the qtsource with both -qt-zlib and -system-zlib configure command but still i am getiing the same warning and woff font not yet supported.so pls share your ideas with me.

Regards,
premji

memory is leak?

QList QWin32PrintEnginePrivate::queryResolutions() const
{
// Read the supported resolutions of the printer.
QList list;

DWORD numRes = DeviceCapabilities(reinterpret_cast<const wchar_t *>(name.utf16()),
                                  reinterpret_cast<const wchar_t *>(port.utf16()),
                                  DC_ENUMRESOLUTIONS, 0, 0);
if (numRes == (DWORD)-1)
    return list;

LONG *enumRes = (LONG*)malloc(numRes * 2 * sizeof(LONG));

//-----------------\
the enumRes not free ?
