wkhtmltopdf | C # wrapper around excellent wkhtmltopdf console utility | Document Editor library

I have a custom Docker build of nginx and php-fpm that I am pretty sure was working until recently. I am now getting the error mentioned above during a build using the DockerFile below when using 8.0-fpm, but not with 8.1.1-fpm-bullseye, although there are some other issues with using 8.1.1 in some of the PHP code (deprecations and warnings).

Im trying to save an html file as an image using imgkit in google colab. Im having trouble making it work.

I have a Python code that is creating HTML Tables and then turning it into a PDF file. This is the output that I am currently getting

This image is taken from PDF File that is being generated as result (and it is zoomed out at 55%)

I want to make this look better. Something similar to this, if I may

This image has 13 columns, I don't want that. I want to keep 5 columns but my major concern is the size of the td in my HTML files. It is too small in width and that is why, the text is also very stacked up in each td. But if you look at the other image, text is much more visible and boxes are much more bigger width wise. Moreover, it doesn't suffer from height problems either (the height of the box is in such a way that it covers the whole of the PDF Page and all the tds don't look like stretched down)

I have tried to play around the height and width of my td in the HTML File, but unfortunately, nothing really seemed to work for me.

Edit: Using the code provided by onkar ruikar, I was able to achieve very good results. However, it created the same problem that I was facing previously. The question was asked here: Horizontally merge and divide cells in an HTML Table for Timetable based on the Data in Python File

I changed up the template.html file of mine and then ran the same code. But I got this result,

As you can see, that there were more than one lectures in the First Slot of Monday, and due to that, it overlapped both the courses. It is not reading the

The modified template.html file has this code,

I'm converting a .Net 2.1 lambda to 3.1 (or higher) and struggling with resolving the references that convert html to pdf. I'm currently using code from this solution https://github.com/HakanL/WkHtmlToPdf-DotNet, which works fine running a console app in the container. The lambda package is introducing issues that break this logic. Using a new lambda solution with this WkHtmlToPdf-DotNet project, the deployed image fails with this exception

GetModule WkHtmlModuleLinux64 Exception System.DllNotFoundException: Unable to load shared library '/var/task/runtimes/linux-x64/native/libwkhtmltox.so' or one of its dependencies. In order to help diagnose loading problems, consider setting the LD_DEBUG environment variable: libjpeg.so.62: cannot open shared object file: No such file or directory

I am using the LD_DEBUG environment variable which shows before the exception: file=runtimes/linux-x86/native/libwkhtmltox [0]; dynamically loaded by /var/lang/bin/shared/Microsoft.NETCore.App/5.0.12/libcoreclr.so [0]

And I also output to the log a search for the file which yields this line:
GetFilePath res: /var/task/runtimes/linux-x64/native/libwkhtmltox.so

Any suggestions how to continue to troubleshoot this?

Thanks, Reuven

Please note this question is an extension of this previously asked question: How to make Images/PDF of Timetable using Python

I am working on a program that generates randomized Timetable based on an algorithm. For the Final Output of that program, I require a Timetable to be stored in a PDF File.

There are multiple sections and each section must have its own timetable/schedule. Each Section can have multiple Courses whose lectures will be allocated on different slots from Monday to Friday by the algorithm. For my timetable,

• There are 5 days in total (Monday to Friday)
• Each day will have 5 slots (0 to 4 in indexes. With a "Lunch" Break between 3rd and 4th slot)

As an Example, I have created below a dictionary where key represents the Section and the items have a 2D Array of size 5x5. Each Index of that 2D array contains the course details for which the lecture will take place in that slot.

I have a docker-compose.yml that builds about 8 containers made up mostly of mysql, postgres, php-nginx and a few other packages that are custom builds. The production version runs on an UBUNTU host, and my development package runs on Mac OS Catalina with an Intel Chip. The whole thing is also maintained in a private repo on Github.

A collaborator has an M1 Mac, and I'll likely upgrade to an M1 Mac shortly, either a MacBook Pro or the 27" iMac when those are released maybe later this year.

We tried installing the package on his M1 Mac and ran into a few problems, and likely more.

One issue appears to be related to the MySQL build in the compose file (some items removed)

my execute script : C:\\fortest\\wkhtmltopdf.exe http://localhost:5004/X/Y?a1=1&a2=23 google.pdf

I getting the error

'a2' is not recognized as an internal or external command, operable program or batch file.

by browser its look like that :

I hid some of the data because it could be sensitive

I am having trouble using wkhtmlpdf gem on my machine. OS - ZorinOS. This is the error I am getting when trying to download or view a pdf file on the rails server -

Error: PDF could not be generated! Command Error: /home/my-user/.rvm/gems/ruby-3.0.1@somename/gems/wkhtmltopdf-binary-0.12.6.5/bin/wkhtmltopdf:61:in `': Invalid platform, must be running on Ubuntu 16.04/18.04/20.04 CentOS 6/7/8, Debian 9/10, archlinux amd64, or intel-based Cocoa macOS (missing binary: /home/my-user/.rvm/gems/ruby-3.0.1@somename/gems/wkhtmltopdf-binary-0.12.6.5/bin/wkhtmltopdf_zorin_16_amd64). (RuntimeError)

I tried following this command to try to resolve which I found on a GitHub issue for wkhtmltopdf_binary_gem. But this too could not solve it.

I have an existing php:8-fpm-alpine Dockerfile, and i need to add WKHTMLTOPDF package. Is that even possible. I tried using following dockerfile, but i get following error log:
