Do we really need to worry about browsers which don't support GIF
in 2008? What browsers would these be, and what OS would they conceivably
be running on?
Windows 3.1? :)
PNG doesn't support layers, no.
For off-line viewing, the format of choice for a map like this (where the
text is rendered as real text, in a font)
would be PDF (although - if you build it in PSP, I don't think you'll get
that - you'll need to build it in Illustrator
or similar).
For online display with layers and real text, the new-fangled SVG would
probably be the thing...

never use JPEG format for a map like this, it munges all the

Use a lossless compression format such as PNG.
this?) we're using GIF images for our B/W illustrations. How would that
work out with this map? (Might require some colour adjustments.)
I think the loss of clarity would be too great right now. If I replaced
all the roads with a more solid colour, it would reduce the number of
colours in the image by a couple of hundred--if not more. I am seriously
considering replacing the roads.
One thing I forgot to mention is that my source image, the one I am
currently working on, is not a PNG but an uncompressed pspimage file. This
is because PNG doesn't seem to support layers. All the labels and
inter-state numbers are actually held on a transparent layer, separate
from the main map image. This allows the position of any of the labels to
be tweaked without having to worry about colour-matching and repainting
the background colour. :-)
If I do the roads, they'll probably be held on a third layer for my own
sanity's sake.
I do have a life myself! ;-)
No way. You're not fooling us... ;-)
See, clearly I do. I managed to resist responding to this immediately! :-p
