WORD EngineRealizeFont(lplf, lpTextXForm, lpFont)
LPLOGFONT lplf;            /* points to logical font information        */
LPTEXTXFORM lpTextXForm;   /* points to text appearance information     */
LPFONT lpFont;             /* points to a buffer for physical font info */
 
The EngineRealizeFont function creates an engine font having attributes and
an appearance that matches those specified by the given logical font and
text appearance information. A driver calls this function, while processing
calls to its RealizeObject function, to determine whether a suitable
TrueType font exists.
 
Import Module.Ordinal: GDI.302.
 
Parameter    Description
────────────────────────────────────────────────────────────────────────────
 
lplf         Points to a LOGFONT structure specifying the attributes of the
             font to create.
 
lpTextXForm  Points to a TEXTXFORM structure specifying additional
             attributes of the font to create.
 
lpFont       Points to a FONTINFO structure or is NULL. If this parameter
             points to a structure, the function fills the structure with
             information about the engine font. Otherwise, the function
             returns the size (in bytes) of this information but does not
             return the information.
 
Return Value
 
This function returns either a size or a Boolean value, depending on the
value of the lpFont parameter.
 
If lpFont is NULL, the function returns the size (in bytes) of the FONTINFO
structure and any additional information needed to describe the engine font.
If the return value is 0, the driver should not attempt to realize the
engine font.
 
If lpFont points to a FONTINFO structure, the function returns TRUE if it
successfully realizes the engine font. Otherwise, it returns FALSE.
 
Comments
 
A driver must call this function twice: first to retrieve the size (in
bytes) of font information to be returned, and second to realize the engine
font and retrieve the corresponding FONTINFO structure. The driver should
then compare its own device fonts with the realized engine font (if any) to
determine which font must closely matches the given logical font
attributes.
 
A driver can use the high byte of the dfType field and the dfBitsOffset and
dfBitsPointer fields for its own purpose. For example, a driver can set the
dfBitsOffset field to point to additional information after the end of the
FONTINFO structure and set bits in the high byte of the dfType field to
specify whether the font passed is an engine or device font. A driver can
use this information when GDI returns the FONTINFO structure in a call to
the StrBlt or ExtTextOut function.
