GetFontResourceInfo 函数: 获取字体文件对应的字体名

在 win 7, gdi32.dll，找不到 GetFontResourceInfo(), 但能找到 GetFontResourceInfoW(), 用法类似。

GetFontResourceInfo

The GetFontResourceInfo function retrieves information from a font resource file.

BOOL GetFontResourceInfo(
  LPCTSTR lpszFilename, // font file name
  LPDWORD cbBuffer,     // size of buffer for resouce information
  LPVOID lpBuffer,     // buffer for returned resouce information
  DWORD dwQueryType,         // resouce information query type
);

Parameters

 

lpszFilename

[in] Pointer to a null-terminated character string that contains a valid font file name. This parameter can specify any of the following files. File extension Description .fon Font resource file. .fnt Raw bitmap font file. .ttf Raw TrueType file. .ttc East Asian Windows: TrueType font collection. .fot TrueType resource file. .otf PostScript OpenType font. .mmm multiple master Type1 font resource file. It must be used with .pfm and .pfb files. .pfb Type 1 font bits file. It is used with a .pfm file. .pfm Type 1 font metrics file. It is used with a .pfb file.

To add a font whose information comes from several resource files, point lpszFileName to a string with the file names separated by a | –for example, abcxxxxx.pfm | abcxxxxx.pfb.

cbBuffer

[in,out] Specifies the length, in bytes, of the information to be retrieved. If this parameter is zero, GetFontResourceInfo returns the size of the data specified in the dwQueryType parameter.

lpBuffer

[out] Pointer to a buffer that receives the font information. If this parameter is NULL, the function returns the size of the buffer required for the font data.

dwQueryType

Specifies the type of resouce information to return. This parameter can be one of the following values.

Value	Meaning
QFR_0  0	DWORD or LPVOID  unknown
QFR_DESCRIPTION  1	The function provides a string that an NT-based operating system will use to describe the font file. A null-terminated Unicode string is written to the buffer pointed to by lpBuffer.
QFR_LOGFONT  2	Array of LOGFONT
QFR_PDEV  3	PDEV ?
QFR_FONTFILE  4	scalable font file name

When 4 is specified in dwQueryType and lpszFilename specifies a FOT file, then lpBuffer returns the file name of the linked .ttf file.
