Low quality image and corrupted PDF obtained

[mphirke]

I'm using Windows 10 version 21H1, Python 3.6. I'm using the sample file Logger Bot. I am getting very low quality (in bytes) image from the bot. Am I doing something wrong? I used pip install and installed python-magic and it's dependencies because they were not available.

I'm using Gecko driver.

Hi, how are you downloading the images?

[mphirke]

I'm using the sample code. Does it not automatically download the media? I'm getting it downloaded in a folder created by sample code (folder named chat_91968941XXXX@c.us) I am not using docker and I'm using Geckodriver. I'm using it with Whatsapp business app. These are the files I got (Image and PDF) that was downloaded in the folder 1377656101296.pdf

change

message.save_media('chat_{id}'.format(id=message.chat_id['_serialized']))

to

message.save_media('chat_{id}'.format(id=message.chat_id['_serialized']), force_download=True)

the file you provided above is a preview file generated by whatsapp before the file being downloaded, not sure about the corrupted pdf issue, but using force_download option should fix those problems

Thank you, that solved it.
