I can't reproduce this issue.
Are there any conditions for reproducing?

Same issue as author. Can I somehow help to investigate it?
Only error in logs I see is:
pdf: Image: error: RBPDF error: Image filename is empty.
It is repeated for each image

How do you describe the contents of the wiki?

The cause is unknown, but the image does not seem to be found.
Is Wiki notation textile or markdown?
Updated by Pawel Szafer over 6 years ago
I've tested both notations textile and markdown.
How do you describe the contents of the wiki?
Don't understand what you mean, but it is mostly markdown text with png images in it. I removed alpha channel from PNG but without any luck.
Installed redmine on Arch Linux and Alpine Linux already.
I can give it a try and make Dockerfile if that helps somehow.

Hello, I confirm this trouble. since we have update from 3.2.1 to 3.4.5
I've exactly the same problem, no png appears in the exported wiki page but jpg are visible.
I will add that we noticed a considerable size increase in exported pdf file with the PNG!

I noticed this bug in our installation as well. Embedding images in the browser works well, but PDF export results in PNG images not showing correctly. It seems as though only the alpha channel is rendered in the PDF – is that plausible? I did not see any errors or warnings in our logs. A screenshot of the resulting PDF (in Adobe Reader) is attached. (The alpha channel is basically a slight shadow around the PNG image, which is rendered in stark contrast in the PDF.)
Our redmine setup is as follows:
Environment: Redmine version 3.4.4.stable.17194 Ruby version 2.4.1-p111 (2017-03-22) [x86_64-linux] Rails version 4.2.8 Environment production Database adapter Mysql2 SCM: Subversion 1.9.3 Git 2.7.4 Filesystem Redmine plugins: clipboard_image_paste 1.12 redmine_checklists 3.1.9 redmine_editauthor 0.11.0 redmine_highlightjs 1.0.3 redmine_lightbox2 0.4.3 redmine_mentions 0.0.1 redmine_percent_done 1.1.0 redmine_tags 3.2.2
We are using Markdown syntax.
Please let me know if I can provide any other helpful information.

I was able to reproduce this problem.
The cause of this problem is rmagick.
But, the implementation of RBPDF also has a problem and will be fixed.
I have created RBPDF's issue.

Updated by Jun NAITOH over 6 years ago
This problem fixed by rbpdf 1.19.4.
please bundle update.

bundle update and restart webserver should be enough?
For me it is not working...
# gem list rbpdf (1.19.4) rbpdf-font (1.19.1)
Same bug still:
pdf: Image: error: RBPDF error: Image filename is empty.

Please tell me the followings.
- An image in which the probrem occurs.
- Your environment. (OS, x86 or x64, ruby version, rmagick version, Imagemagick version)

All three images I attached in post above are problematic.
changed name of last image (with white background and Test sign) to 'test.png' and it is working...
For rest of images, which are more complex name changing doesn't help really.

Thanks your information.
I tried installing RMagick on Alpine Linux v3.7(x86_64) Extended.But RMagick (2.16.0) does not seem to support ImageMagick 7.
Is not it a problem with your environment?

Hi,
After bundle update and Redmine app restart, rbpdf 1.19.5 works fine and all png images exported to pdf correctly on our environment.
Thank you for your time and effort, Naito san, Maeda san and Mr.Pawel Szafer.
