Exported PDF does not include images

[mdev88]

Hello, I'm not sure if there is a problem with my installation of HackMD, but when I export as PDF, all the images appear as "broken image" icons.

This happens with external images and images uploaded by me in HackMD as well.

Any ideas?

Thanks!

Can you provide a document to reproduce it?

Seems to be working when I use our features page: https://hackmd-ce.herokuapp.com/features#

Thanks for the quick reply!

Okay, after a quick test, this is caused by relative links that are created on upload.

Not sure how to fix it yet, but at least we know what's wrong. This only happens when filesystem is used as upload method.

Allright! If you need anything else just let me know.

I think maybe convert the img src starts with / to file:/// might help.

I continue to have an issue with generated PDFs not showing images (using latest v1.2.1 built with docker-compose).

For an example see: https://codimd.greenant.net/tDha9czKRXm30iW-dqOHFg#

The image URLs appears to be generated properly (as a full URL with https://) but there is no image visible in the PDF.

my relevant environment variables are:

      - CMD_DOMAIN=codimd.greenant.net
      - CMD_PROTOCOL_USESSL=true
      - CMD_USECDN=false
      - CMD_URL_ADDPORT=false
      - CMD_IMAGE_UPLOAD_TYPE=filesystem

@zeigerpuppy can you check that wget -O- https://codimd.greenant.net/tDha9czKRXm30iW-dqOHFg/download from inside the container results in the markdown of your instance printed out to your cli?

My current guess why it fails in your case is that your container doesn't have access to the outside address of your reverse proxy.

Thanks @SISheogorath, that was the issue!

I have now set my internal DNS server to redirect to the local web proxy (internal address) and now the PDF export works.
