Dario Taraborelli <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[email protected] --- Comment #11 from Dario Taraborelli <[email protected]> --- I'm interested in following up on this bug, particularly for PDFs of vectorial graphs generated from data analysis software (like R or Mathematica), which researchers (including myself) routinely upload to Commons. The quality of JPEG thumbnails for these PDF graphs is abysmal when compared to a thumbnails for a native PNG format. Original files: https://commons.wikimedia.org/wiki/File:Active_Editors_arwiki.pdf https://commons.wikimedia.org/wiki/File:Active_Editors_arwiki_2.png Thumbnails: https://upload.wikimedia.org/wikipedia/commons/thumb/3/39/Active_Editors_arwiki.pdf/page1-1004px-Active_Editors_arwiki.pdf.jpg https://upload.wikimedia.org/wikipedia/commons/0/06/Active_Editors_arwiki_2.png The only other option for vectorial plots to avoid these compression artifacts is to upload them as SVG (which renders as PNG). However in many cases PDF is the default export option and the most common format for scientific media people will consider donating to Commons. -- You are receiving this mail because: You are the assignee for the bug.
