PNGs are not resolution independent, although they are perfectly
acceptable. Saving as a TIFF then converting it to PDF with
Preview works well for me.
Please excuse me if I missed something earlier in the thread, but
my understanding of TIFFs (and PNGs and JPEGs) is that they're all
purely raster formats. Thus, how does saving a TIFF as a PDF get
you resolution independence? (At least that's what I read you to
be saying.)
I'm not entirely sure. I saved a TIFF file from the GIMP, and yes,
it does look like raster. But there is evidently more information
there, as when I converted it to PDF in Preview, it saved it as a
scalable format. I don't know how, but it evidently worked.
So if you scale the PDF to different sizes, is the image from the
TIFF always crisp (no jaggy edges, etc.)?
The PDF never seems to get jaggy edges. The original TIFF file does,
but the PDF remains fine. I think it depends in part on what
application you use.
