  • Hi. I tried: \logo{\tikz\node[opacity=.1,inner sep=0pt] {\includegraphics[scale=0.65]{segl.pdf}};} but i had no success :( Jan 25 '16 at 10:10
  • Worked after exporting the PDF into PNG. Thank you Jan 25 '16 at 10:15
  • Weird. It should also work for the PDF, except when the PDF is not an actual vector graphic but just a page with an embedded image. Jan 25 '16 at 10:44
  • For me it works with the PDF. I downloaded the SEGL logo as SVG from Wikipedia and converted it to PDF using inkscape --export-pdf=segl.pdf Aarhus_University_seal.svg. Then, with this sample document you can achieve the desired effect. Jan 25 '16 at 10:50
