FONTSIM structure (winddi.h)

The FONTSIM structure contains offsets to one or more FONTDIFF structures describing bold, italic, and bold italic font simulations.

typedef struct _FONTSIM {
  PTRDIFF dpBold;
  PTRDIFF dpItalic;
  PTRDIFF dpBoldItalic;
} FONTSIM;

dpBold

If nonzero, specifies the offset from the beginning of this structure to the FONTDIFF structure describing the bold simulation. If this member is zero, the font does not support bold simulation.

dpItalic

If nonzero, specifies the offset from the beginning of this structure to the FONTDIFF structure describing the italic simulation. If this member is zero, the font does not support italic simulation.

dpBoldItalic

If nonzero, specifies the offset from the beginning of this structure to the FONTDIFF structure describing the bold italic simulation. If this member is zero, the font does not support bold italic simulation.

If the dpFontSim member of the IFIMETRICS structure is nonzero, it holds the offset from the beginning of that structure to the beginning of a FONTSIM structure.
