typedef struct _DgReferencePoint {
DgInt16 u;
DgInt16 v;
DgInt16 x;
DgInt16 y;
} DgReferencePoint;
Summary
A reference point binds a logical glyph coordinate (u,v) to a physical pixel coordinate (x,y). Both coordinate systems have their origin in the upper left hand corner, and typically only have positive values.
Members
u,v
logical position in glyphmark lattice
x,y
pixel position at center of glyphmark
