Hi Eduardo,

I also agree that in terms of resolution (pix per inch ) pdf and jpg are the same. However, pdf (and SVG) allow the image to be scaled with little loss in image quality. In my lab we typically save the images in pdf because the most biomedical journals don’t accept SVG file format (not yet).

Thanks,
M
PS Since emacs can display SVG, we are planning to use this as our default file format during the manuscript generation stage, and then convert to pdf at the end (just before submitting)

But emacs con show svg files directly (see https://urldefense.proofpoint.com/v2/url?u=https-3A__www.emacswiki.org_emacs_EmacsSvg&d=DwIDaQ&c=kbmfwr1Yojg42sGEpaQh5ofMHBeTl9EI2eaqQZhHbOU&r=s3_3riAscdqtNAzgOuwYB9g0dZVGcp8BNCy_RylYdxU&m=ToUr47iyS79VqRe2JGHpKEuFdjOC7Ae_27eFPP0IW_w&s=7L3s6Qt1QD87OGVmmSwlgpqsI1HZOUvEVFP6izsIYmc&e= ).
