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

Syntax

typedef struct _GETINFO_STDVAR {
  DWORD                   dwSize;
  DWORD                   dwNumOfVariable;
  struct {
    DWORD dwStdVarID;
    LONG  lStdVariable;
  };
  __unnamed_struct_1546_3 StdVar[1];
} GETINFO_STDVAR, *PGETINFO_STDVAR;

Members

dwSize

Specifies the size, in bytes, of the GETINFO_STDVAR structure. Supplied by the UNIFONTOBJ_GetInfo caller.

dwNumOfVariable

Defines the DWORD member dwNumOfVariable.

dwStdVarID

Defines the DWORD member dwStdVarID.

lStdVariable

Defines the LONG member lStdVariable.

StdVar[1]

An array specifying standard variable indexes and values. Each array element contains two members: a dwStdVarID member and an lStdVariable member.

dwStdVarID

Specifies the standard variables for which a value should be returned. Supplied by the UNIFONTOBJ_GetInfo caller. Valid values are contained in the following table.

Identifier	Standard Variable
FNT_INFO_CURRENTFONTID	CurrentFontID
FNT_INFO_FONTBOLD	FontBold
FNT_INFO_FONTHEIGHT	FontHeight
FNT_INFO_FONTITALIC	FontItalic
FNT_INFO_FONTMAXWIDTH	FontMaxWidth
FNT_INFO_FONTSTRIKETHRU	FontStrikeThru
FNT_INFO_FONTUNDERLINE	FontUnderline
FNT_INFO_FONTWIDTH	FontWidth
FNT_INFO_GRAYPERCENTAGE	GrayPercentage
FNT_INFO_NEXTFONTID	NextFontID
FNT_INFO_NEXTGLYPH	NextGlyph
FNT_INFO_PRINTDIRINCCDEGREES	PrintDirInCCDegrees
FNT_INFO_TEXTXRES	TextXRes
FNT_INFO_TEXTYRES	TextYRes

Supplied by the UNIFONTOBJ_GetInfo caller.

lStdVariable

Specifies the current value of the specified standard variable. Supplied by Unidrv's UNIFONTOBJ_GetInfo callback function.

Remarks

To obtain the current value for one or more of Unidrv's standard variables, a rendering plug-in can supply the address of a GETINFO_STDVAR structure when calling Unidrv's UNIFONTOBJ_GetInfo callback function.
