Question

"kern" table ignored? -- technical note "OpenType tables used by Windows"

The technical note "OpenType tables used by Windows"<br /> http://partners.adobe.com/asn/developer/type/otfdk/<br /> techdocs/OT_tables_in_Win_ATM.html<br />says that the <kern> table (Kerning) is "Ignored". Is it true? Does the ATM<br />driver really ignore "flat" kerning?<br /><br />Also, are there any significant updates for Windows 2000 and XP? (I think<br />the ATM font driver built in Windows 2000 and XP is referred to as "5.0" --<br />true?)<br /><br />Adam

Yes, that's exactly correct, I'm afraid.

Hi, Adam,

Yes, the kern table is ignored in favor of the GPOS kern feature, for OTF-flavored OpenType fonts.

The GPOS kern feature can be used to represent pair-based "flat" kerning as well as class-based kerning.
