If you are trying to import pdf into power point slides they will be converted into low-resolution PNGs (or even JPEGs), thus the blurry image. If you are trying to produce presentation with power point and PDFs images than, yes, the best option is to use high-resolution PNGs. But the problem is Power Point, not NCL :P <div class=""><br class=""></div><div class="">Ideally the best way of producing presentation is to use, when possible, vector image data as the presentation will most likely be reproduced on a projector/screen that does not have the same resolution/aspect ratio of your laptop/computer. With PDF you are always on the safe side, as you know that images will be adapted to every situation. <br class=""><div class=""><br class=""></div><div class="">Cheers</div><div class=""><br class=""></div><div class=""><div><blockquote type="cite" class=""><div class="">Il giorno 08 lug 2017, alle ore 20:05, Barry Lynn <<a href="mailto:barry.h.lynn@gmail.com" class="">barry.h.lynn@gmail.com</a>> ha scritto:</div><br class="Apple-interchange-newline"><div class=""><div dir="ltr" class="">Dear Guido:<div class=""><br class=""></div><div class="">I appreciate that you're trying to explain this to us.</div><div class=""><br class=""></div><div class="">I made a pdf and png of the same multi-paneled image.
