I agree with both Dan and Alex, since both are partially correct in my opinion.
A bitmap font contains font metrics but it does NOT contain 'hinting',
which effects spacing as well. For those who are interested, 'hinting'
refers to Adobe's once-uncrackable encrypted crown jewels that custom
altered character formation: serifs, stems, x heights, and the like. The
point of hinting is to increase the viewabiity of fonts at low resolutions
as well as at tiny sizes (imaged and printed.) It is contained in the
Postscript font and is passed to the basic printer control program in the
printer, during the printing process (if the Postscript font does not
already reside in the printer ROM).
TrueType fonts also contain 'hinting'. In Fontographer, you can edit or
turn on/off either the horizontal and/or the vertical hinting, which
obviously affects the spacing.
ATM uses BOTH the outline and bitmap file to generate the on-screen font,
not just the Postscript information. However, ATM has a pecking order when
it does this, it doesn't do it randomly.
The Preserve Line Spacing and Preserve Line Shapes options in ATM do NOT,
as Mr. Schwarz implies, ONLY work doing the rasterizing process. They are
used during the printing OR DISPLAY process to alter spacing of characters
containing diacritics/accents. If you have any doubts, please refer to Page
15 of the ATM manual for a further explanation.
Bye for now,
