GETINFO_GLYPHWIDTH structure (printoem.h)

The GETINFO_GLYPHWIDTH structure is used as input to the UNIFONTOBJ_GetInfo callback function.

Syntax

typedef struct _GETINFO_GLYPHWIDTH {
  DWORD dwSize;
  DWORD dwType;
  DWORD dwCount;
  PVOID pGlyph;
  PLONG plWidth;
} GETINFO_GLYPHWIDTH, *PGETINFO_GLYPHWIDTH;

Members

dwSize

Size, in bytes, of the GETINFO_GLYPHWIDTH structure. Supplied by the UNIFONTOBJ_GetInfo caller.

dwType

Specifies the type of the glyph specifier array pointed to by pGlyph. Valid values are:

• TYPE_GLYPHHANDLE

• TYPE_GLYPHID

Supplied by the UNIFONTOBJ_GetInfo caller.

dwCount

Specifies the number of elements in the array pointed to by pGlyph. Supplied by the UNIFONTOBJ_GetInfo caller.

pGlyph

Pointer to an array of glyph specifiers. The array element type is indicated by dwType. Supplied by the UNIFONTOBJ_GetInfo caller.

plWidth

Pointer to a ___location into which Unidrv's UNIFONTOBJ_GetInfo callback function places the width value. The pointer is supplied by the UNIFONTOBJ_GetInfo caller.

Remarks

To obtain the width of a set of glyphs, a rendering plug-in can supply the address of a GETINFO_GLYPHWIDTH structure when calling Unidrv's UNIFONTOBJ_GetInfo callback function. The callback function calculates the total width of all the glyphs described by the input array, and places the calculated value in the ___location pointed to by plWidth.
