Please add auto compression if a file is too large to convert. Or make larger files be able to convert, please.
Hello, could you provide some additional details to this issue? I fail to understand what is the problem you encountered. Could you for example provide some code where html2image cannot handle a "large file"?

Not to say that otherwise I am not very pleased with this library - I am.
Hello,
Your example is very detailed, but it is incomplete and I can't test it on my machine.
The errors and warnings you're seeing come directly from Chrome/Chromium and are not directly related to Html2Image.
Could you try to add the following flags to see if that fixes the issue ?
--disable-software-rasterizer, --disable-gpu
You can add them like so, anytime before taking a screenshot:
hti.browser.flags.extend(['--disable-software-rasterizer', '--disable-gpu'])
I added the flags, and still got this error:

What did you mean the example is incomplete?
You can download the project here. Choose '2048 Wallpaper'.
"Minimal reproducible examples" (you can read about it here) are usually appreciated when asking for help online with code or debugging.
In our case, I'm missing the options.json and template.html files, so the code can't be run.
It's not a big deal for the json file, but it's more problematic for the html file.
Concerning the errors, I don't think there is anything I can really do. Html2Image is only but a wrapper around the headless mode of existing browsers, such as Chrome. The errors that are displayed in your console are printed by Chrome, meaning the browser has some issues with the files you gave it (or the configuration of the browser itself, or maybe there is a bug with this version, etc.).
When searching for WARNING: tile memory limits exceeded, you can find threads such as this one suggesting to update your chrome version for force a specific version. If this doesn't help, I'm afraid that I won't be able to help more, the only things that could be done are:
- Search for the error codes on a search engine and try the solutions
- Open one or more issues on https://bugs.chromium.org
If you have the template.html file, I could try to see if i get the same errors.
I gave you a link to download the whole project, including the other files.
The only file I can see in the archive is Code Generator.py (+ an .idea and a venv folder).
