GETINFO_GLYPHWIDTH structure (printoem.h)

  • Article

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.
