XFont - Get font name and file information

• Download demo project - 33 Kb

Introduction

XFont comprises two functions that are useful when trying to determine the name of the font file given the font name, and conversely when trying to find the font name from the font file. I have already introduced GetFontFile() in a previous article. This article presents a new non-MFC version of GetFontFile() and also GetFontProperties(), which together allow you to find the name of the font or the name of the font file.

First, let me acknowledge the work of Philip Patrick, who researched the font file format to come up with GetFontProperties(). I have taken his code and removed the MFC dependencies, added Unicode support, and converted the CFile file I/O to a memory-mapped file.

XFont Functions

• GetFontFile() - Find the name of font file.

  ///////////////////////////////////////////////////////////////////////////////
  //
  // GetFontFile()
  //
  // Purpose:     Find the name of font file from the font name
  //
  // Parameters:  lpszFontName     - name of font
  //              lpszDisplayName  - pointer to buffer where font display name
  //                                 will be copied
  //              nDisplayNameSize - size of display name buffer in TCHARs
  //              lpszFontFile     - pointer to buffer where font file name
  //                                 will be copied
  //              nFontFileSize    - size of font file buffer in TCHARs
  //
  // Returns:     BOOL - TRUE = success
  //
  // Notes:       This is *not* a foolproof method for finding the name of a
  //              font file. If a font has been installed in a normal manner,
  //              and if it is in the Windows "Font" directory, then this method
  //              will probably work. It will probably work for most screen
  //              fonts and TrueType fonts. However, this method might not work
  //              for fonts that are created or installed dynamically, or that
  //              are specific to a particular device, or that are not installed
  //              into the font directory.
  // 

• GetFontProperties() - Get font name from font file.

  ///////////////////////////////////////////////////////////////////////////////
  //
  // GetFontProperties()
  //
  // Purpose:     Get font name from font file
  //
  // Parameters:  lpszFilePath - file path of font file
  //              lpFontPropsX - pointer to font properties struct
  //
  // Returns:     BOOL - TRUE = success
  // 

How To Use

To integrate XFont into your app, you first need to add following files to your project:

• XFont.cpp
• XFont.h

If you include XFont in project that uses precompiled headers, you must change C/C++ Precompiled Headers settings to Not using precompiled headers for XFont.cpp.

Next, include the header file XFont.h in appropriate project files. Now you are ready to start using XFont. The two XFont functions are demonstrated fully in the XFont demo app.

Demo App

The XFontTest.exe demo tests the APIs in XFont. Here is some of the output:

XFont on Vista 64bits Mirco Babin 2:40 1 Jul '09   The GetWinVer is not usable on Windows/Vista, because at the time it was written only Windows/XP existed. I removed the GetWinVer() function and all related lines. I have replaced this function with: /////////////////////////////////////////////////////////////////////////////// // // GetWindowsPlatform() // // Purpose: Get Windows platform // // Returns: int - platform // 0 UNKNOWN // 1 Win/95, Win/98, Win/ME // 2 Win/NT, Win/2000, Win/XP, Win/VISTA // 3 Win/CE static int GetWindowsPlatform(void) { OSVERSIONINFO osinfo; memset(&osinfo, 0, sizeof(OSVERSIONINFO)); osinfo.dwOSVersionInfoSize = sizeof(OSVERSIONINFO); if (GetVersionEx(&osinfo)) { switch (osinfo.dwPlatformId) { case 1: return 1; case 2: return 2; case 3: return 3; } } return 0; } Off course the GetFontFile() function also has to be adjusted: int nPlatform = GetWindowsPlatform(); TRACE(_T("nPlatform=%d\n"), nPlatform); TCHAR szFontPath[1000]; switch (nPlatform) { case 1: //Windows 95 _tcscpy(szFontPath, _T("Software\\Microsoft\\Windows\\CurrentVersion\\Fonts")); break; case 2: //Windows NT _tcscpy(szFontPath, _T("Software\\Microsoft\\Windows NT\\CurrentVersion\\Fonts")); break; default: TRACE(_T("Windows platform not supported")); return FALSE; } Sign In·View Thread·PermaLink XFont on Vista shanem 2:06 2 Oct '07   XFont is prone to crash on Vista due to a NULL pointer issue in the GetWinVer function. A simple work around is to change line 669 of Xfont.cpp from _tcsncpy(lpszVersion, cp, nVersionSize-1); to if (cp) _tcsncpy(lpszVersion, cp, nVersionSize-1); Regards and thanks for the package, Shane Sign In·View Thread·PermaLink Can I copy font data? dzungthenguyen@yahoo.com 2:14 17 Jun '05   suppose we have Courier and Arial font.

Maybe that's interessting for some of you: the Paths for type 1 fonts are stored in HKEY_LOCAL_MACHINE\Software\Microsoft\Windows (NT)\CurrentVersion\Type 1 Installer\Type 1 Fonts of course, you won't get the display names for these files with this code because they're stroed in PFM / PFB files and not in TTF bye King Nak Sign In·View Thread·PermaLink A little bug in the GetNextNameValue Zwer2k 0:07 3 Dec '03   If you are loged not as Admin and have only normal-rights or you ar a guest then this application will not work. You should make a change in the GetNextNameValue function. Replace KEY_ALL_ACCESS with KEY_READ. The Problem is that a limitted user have not full-access to the HKEY_LOCAL_MACHINE. The consequence is that RegOpenKeyEx will return a error.

While printing these fonts to the printer i am using wingdi function EXtEscape() for GETFACENAME and DOWNLOADFACENAME. The facename returned by the ExtEscape() for GETFACENAME is different in different printer for these Postscript(T1) outline opentype fonts. Like I have used the Xerox Phaser 2135 PS3(here ExtEscape returns the face name TT*******) and Lexmark W820 PS3 (Extescape() returns the facename like postscriptfontname021*** eg.. TektonPro-Regular0123***). So my question is is this the correct behaviour of returning the different facename in different printer? How the printer driver returns these face names ? while printing these fonts how it download these fonts?
