I use MWLIB to generate PDF articles from MediaWiki documents. We use PlantUML with Graphviz 2.30.0.
Of some strange reason, under the UML diagram pictures strange grey lines always appear on the converted PDF-files. See picture.
Anyone got any idea of to fix this and take away the grey lines? Thanks in advance!
The grey lines shows up only in the PDF-documents, not the WikiaArticles they were generated from.
When you view the PDF file in Ubuntu, the entire images has a grey border around it, and in Windows it's only the line below the image like in the picture above.
