Subject:RE: Why JPGs for screen captures? test results From:"Sean Brierley" <sbri -at- haestad -dot- com> To:"TECHWR-L" <techwr-l -at- lists -dot- raycomm -dot- com> Date:Thu, 27 Feb 2003 10:47:06 -0500
EMFs reference fonts, they don't embed them like EPS does. Furthermore,
I have found some display discrepancies with complex vectors, though it
is a better format than WMFs which (I believe) uses short straight
segments for some splines and curves. I have had font spacing, kerning,
and other issues with fonts in EMF that were converted to curves, too.
Finally, it's Windows only.
The only problem I can think of with PNGs is that they don't support
CMYK color. I believe--don't know for absolute certainty--that they
support RGB+transparency. I use PNGs for my online help output. They
work fine. PNG is a raster format, btw.
Two questions for Sean re the following snips from his separate posts:

1. Why only "in a pinch"? What's the disadvantage in working with EMFs
for
vector images?
> Non-lossy compression is used in things like PNG, where the
compression
> algorithm does not discard data from the file.
2. Is there *any* disadvantage in using PNGs for raster images?
