HtmlConverter not working in Linux

[mcgammelgaard]

Hi

We are using a licenced version of Spire.PDF (version 7.8.2) in a c# .Net Core 5 application where we are converting html to pdf using Spire.Pdf.HtmlConverter.Qt;

This works fine in windows but when we put it into a linux docker container the convert method just returns an empty stream.

The issue seems to be related to this post of the name "Spire.Pdf.HtmlConverter.Qt.HtmlConverter - LinuxOs" (for some reason I'm not allowed to write URL's in this post.)

We started out with the same issues that the plugins couldn't be found and by running the update commands as suggested we got past that error but now the convert method just returns nothing without throwing any errors.

I have checked the file permissions like you also suggested in the other post.
Any ideas?

Linux OS details:

PRETTY_NAME="Debian GNU/Linux 10 (buster)"
NAME="Debian GNU/Linux"
VERSION_ID="10"
VERSION="10 (buster)"
VERSION_CODENAME=buster
ID=debian

Hi,

Thanks for your inquiry.
Our Spire.Pdf uses QT plugin to convert HTML to PDF, the QT plugin requires GUI support, while the docker has no graphical interface. So I suggest that you first install xvfb in the docker environment, then force to use the xvfb command to run your dotnet project.
sample code like :

Code: Select all

RUN xvfb-run dotnet publish -c Release -o out

If the problem still exists, please provide your dockerfile for our further investigation. You could attach it here or send to us via email ([email protected]). Thanks in advance.
