Hi Marvin.
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.
Sorry to disagree, but again, pdf images can be vector (like svg)
and infinitely scaled or raster (bitmap, as a jpg) and in this
case the quality is on the file. The pdf format only adds and
envelope around the original jpg image, or in the conversion it
can be downscaled.
Just to test this you can extract the images from the pdf and
check their properties. The specific tools depend on your OS of
choice, but at least in Linux there are many options, some command
line based and others GUI based.
In my lab we typically save the images in pdf because the most
biomedical journals don’t accept SVG file format (not yet).
Sure. But why not simply use a jpg or png?
* Journals accept those formats perfectly well,
* you will see them with their best quality, and
* you can see them in emacs buffers natively.
Just try it and you'll see that -if I understood you ok- you will
gain in every dimension. :)
Best...
