HTML to PDF using chromium

[Viswa Prakash]

Hi Everyone,

I need to convert HTML to PDF using chromium, I have built the source in my local windows machine. My aim is to create a C++ wrapper for converting HTML to PDF using the chromium source build in my machine. can anyone provide instructions and suggestions here? 

Chromium source build directory also very large size, and it takes very long time to complete a single build. Is there any option to build the source only for HTML to PDF conversion module. 

Thanks,

Prakash V

I do not want to use chrome pre-build assemblies, I'm aware about print-to-pdf in headless app. But I do not want to headless shell. I need to provide options for conversion from C++ program and convert it to pdf in C++ project.

Headless also has C++ bindings, which might help your case.

Parsing and rendering web content is very complicated. Building a
stripped down version of headless_shell is probably as small as it
gets. The majority of the build time is probably spent building Blink,
which is required because that's the rendering engine.

You also said "I do not want to headless shell" but you need to
elaborate on what you want exactly.

Hi Lei Zhang,

headless shell internally launch the chrome process for converting html to pdf. I do not want to launch chrome process. Instead of this, it is possible to directly convert the HTML to PDF in C++.

If that is really what you want, then Chromium, with its multi-process
architecture, is probably not right for you. See
https://www.chromium.org/developers/design-documents/process-models

The closest you can get is with single process mode, but in my
experience, single process mode is often broken in weird ways.

Just a suggestion - https://wkhtmltopdf.org/ seems to do exactly what you want already, and is also open-source - it might be less work to use that instead of chromium.
