Detailed Description

In the Japanese version of InDesign a feature called "Tsume" is available. This feature removes a percentage of the whitespace from either side of a glyph. It works by getting the exact ink bounding box of a particular glyph and comparing that with the pen-advance. Because this data is completely unavailable when the font is missing, we store the values, as they are used, in this table. Each font that has been used with Tsume has its own table. These tables are available from the IFontMetricTableList.

virtual void IFontMetricsTableList::ClearFontMetricsTable ( const IPMFont *  font )

pure virtual

Clear the table for a particular font. Only called by the Composite Font Manager at this time.

Parameters

font	is the font whose table is to be cleared.

virtual IFontMetricsTable* IFontMetricsTableList::QueryFontMetricsTable ( const IPMFont *  font, bool16  createIfNew  )

pure virtual

return a IFontMetricsTable for a particular font.

Parameters

font	specifies which font you want to get side-bearings for.
createIfNew	specifies if you want "nil" returned if the table doesn't already exist. otherwise, it will create an empty table.

Returns

a AddRef'd IFontMetricsTable interface for the font.
