FileNotFoundError when downloading PDF volumes

[Ethaisa123]

What happened ?

After downloading the chapters when the worker converts the volume into a PDF I get a FileNotFoundError: [Errno 2] No such file or directory: 'C:\Users\Ethan\Downloads\Kobo-pine\New Normal\Vol. 3\000.png

Full error below:

What did you expect to happen ?

I expected the program to convert the Folders into a PDF, in the same way as the cbz method

OS version

Windows 10

App version

mangadex-downloader v2.10.1 (https://github.com/mansuf/mangadex-downloader)
Python: 3.11.2
arch: x64
bundled executable: no

Installation origin

PyPI (Python Package Index)

Installation origin (other sources)

No response

Reproducible command

mangadex-dl https://mangadex.org/title/e1d0056a-fdd3-4f32-af19-50eeb37280ac --save-as "pdf-volume" --use-volume-cover -uvc --progress-bar-layout=none

Additional context

if you repeatedly do the same command over and over every time it crashes it will eventually get through all the chapters (using the download.db I'm guessing)

Man, seems like i messed up when refactoring codes. Sorry about that, i've made PR #79 to fix this issue. You can test it by installing patched version.

Please note that you need git to install patched version

# Make sure you uninstall previous version mangadex-downloader
pip uninstall mangadex-downloader

# Install patched version
pip install -U git+https://github.com/mansuf/mangadex-downloader.git@e4b4e456ca9188d305c1af443a4c947bae570646

The issue was caused by images that want to be converted but the images already been deleted. If you're curious what code has causing this.

mangadex-downloader/mangadex_downloader/format/pdf.py

Line 440 in 206f5cf

self.images = []

Technically PDFVolume.images has been used to store downloaded images for each volumes and after that the application will convert to pdf and delete the images. The problem is PDFVolume.images values never been cleared after previous volumes has been converted, so it will trying to convert images to pdf from previous volumes.
