Wiki PDF export of .png images not working properly
I am running a reasonably current version of Redmine under Centos7
!Screenshot from 2017-11-16 14-22-08.png!
I have several images in my wiki pages that are either .png files included with the "sort form" (!image.png!) or .svg generated from plantuml plugin.
Neither is displayed correctly in exported .PDF files.
I attach an example of the generated document (this one doesn't even have embedded plantuml graphs).
Is there any hope to quickly find the problem? (I urgently need to send these pages for offline viewing)
