Package org.apache.fontbox.ttf
Class VerticalOriginTable
java.lang.Object
org.apache.fontbox.ttf.TTFTable
org.apache.fontbox.ttf.VerticalOriginTable
A vertical origin 'VORG' table in an OpenType font.
The purpose of this table is to improve the efficiency of determining
vertical origins in CFF fonts where absent this information the bounding
box would have to be extracted from CFF charstring data.
This table is strongly recommended by the OpenType CJK Font Guidelines
for "CFF OpenType fonts that are used for vertical writing".
This table is specified only in the OpenType specification (1.3 and later).
