CreateFont
The CreateFont function creates a logical font with the specified characteristics. The logical font can subsequently be selected as the font for any device.

HFONT CreateFont(
int nHeight, // height of font
int nWidth, // average character width
int nEscapement, // angle of escapement
int nOrientation, // base-line orientation angle
int fnWeight, // font weight
DWORD fdwItalic, // italic attribute option
DWORD fdwUnderline, // underline attribute option
DWORD fdwStrikeOut, // strikeout attribute option
DWORD fdwCharSet, // character set identifier
DWORD fdwOutputPrecision, // output precision
DWORD fdwClipPrecision, // clipping precision
DWORD fdwQuality, // output quality
DWORD fdwPitchAndFamily, // pitch and family
LPCTSTR lpszFace // typeface name
);
Parameters
nHeight
[in] Specifies the height, in logical units, of the font's character cell or character. The character height value (also known as the em height) is the character cell height value minus the internal-leading value. The font mapper interprets the value specified in nHeight in the following manner. Value Meaning
> 0 The font mapper transforms this value into device units and matches it against the cell height of the available fonts.
0 The font mapper uses a default height value when it searches for a match.
< 0 The font mapper transforms this value into device units and matches its absolute value against the character height of the available fonts.


For all height comparisons, the font mapper looks for the largest font that does not exceed the requested size.

This mapping occurs when the font is used for the first time.

For the MM_TEXT mapping mode, you can use the following formula to specify a height for a font with a specified point size:

nHeight = -MulDiv(PointSize, GetDeviceCaps(hDC, LOGPIXELSY), 72);
nWidth
[in] Specifies the average width, in logical units, of characters in the requested font. If this value is zero, the font mapper chooses a closest match value. The closest match value is determined by comparing the absolute values of the difference between the current device's aspect ratio and the digitized aspect ratio of available fonts.
nEscapement
[in] Specifies the angle, in tenths of degrees, between the escapement vector and the x-axis of the device. The escapement vector is parallel to the base line of a row of text.
Windows NT/2000/XP: When the graphics mode is set to GM_ADVANCED, you can specify the escapement angle of the string independently of the orientation angle of the string's characters.

When the graphics mode is set to GM_COMPATIBLE, nEscapement specifies both the escapement and orientation. You should set nEscapement and nOrientation to the same value.

Windows 95/98/Me: The nEscapement parameter specifies both the escapement and orientation. You should set nEscapement and nOrientation to the same value.

nOrientation
[in] Specifies the angle, in tenths of degrees, between each character's base line and the x-axis of the device.
fnWeight
[in] Specifies the weight of the font in the range 0 through 1000. For example, 400 is normal and 700 is bold. If this value is zero, a default weight is used.
The following values are defined for convenience. Value Weight
FW_DONTCARE 0
FW_THIN 100
FW_EXTRALIGHT 200
FW_ULTRALIGHT 200
FW_LIGHT 300
FW_NORMAL 400
FW_REGULAR 400
FW_MEDIUM 500
FW_SEMIBOLD 600
FW_DEMIBOLD 600
FW_BOLD 700
FW_EXTRABOLD 800
FW_ULTRABOLD 800
FW_HEAVY 900
FW_BLACK 900



fdwItalic
[in] Specifies an italic font if set to TRUE.
fdwUnderline
[in] Specifies an underlined font if set to TRUE.
fdwStrikeOut
[in] Specifies a strikeout font if set to TRUE.
fdwCharSet
[in] Specifies the character set. The following values are predefined:
ANSI_CHARSET
BALTIC_CHARSET
CHINESEBIG5_CHARSET
DEFAULT_CHARSET
EASTEUROPE_CHARSET
GB2312_CHARSET
GREEK_CHARSET
HANGUL_CHARSET
MAC_CHARSET
OEM_CHARSET
RUSSIAN_CHARSET
SHIFTJIS_CHARSET
SYMBOL_CHARSET
TURKISH_CHARSET
VIETNAMESE_CHARSET

Korean language edition of Windows:
JOHAB_CHARSET
Middle East language edition of Windows:
ARABIC_CHARSET
HEBREW_CHARSET
Thai language edition of Windows:
THAI_CHARSET
The OEM_CHARSET value specifies a character set that is operating-system dependent.

Windows 95/98/Me: You can use the DEFAULT_CHARSET value to allow the name and size of a font to fully describe the logical font. If the specified font name does not exist, a font from any character set can be substituted for the specified font, so you should use DEFAULT_CHARSET sparingly to avoid unexpected results.

Windows NT/2000/XP: DEFAULT_CHARSET is set to a value based on the current system locale. For example, when the system locale is English (United States), it is set as ANSI_CHARSET.

Fonts with other character sets may exist in the operating system. If an application uses a font with an unknown character set, it should not attempt to translate or interpret strings that are rendered with that font.

To ensure consistent results when creating a font, do not specify OEM_CHARSET or DEFAULT_CHARSET. If you specify a typeface name in the lpszFace parameter, make sure that the fdwCharSet value matches the character set of the typeface specified in lpszFace.

fdwOutputPrecision
[in] Specifies the output precision. The output precision defines how closely the output must match the requested font's height, width, character orientation, escapement, pitch, and font type. It can be one of the following values. Value Meaning
OUT_CHARACTER_PRECIS Not used.
OUT_DEFAULT_PRECIS Specifies the default font mapper behavior.
OUT_DEVICE_PRECIS Instructs the font mapper to choose a Device font when the system contains multiple fonts with the same name.
OUT_OUTLINE_PRECIS Windows NT/2000/XP: This value instructs the font mapper to choose from TrueType and other outline-based fonts.
OUT_PS_ONLY_PRECIS Windows 2000/XP: Instructs the font mapper to choose from only PostScript fonts. If there are no PostScript fonts installed in the system, the font mapper returns to default behavior.
OUT_RASTER_PRECIS Instructs the font mapper to choose a raster font when the system contains multiple fonts with the same name.
OUT_STRING_PRECIS This value is not used by the font mapper, but it is returned when raster fonts are enumerated.
OUT_STROKE_PRECIS Windows NT/2000/XP: This value is not used by the font mapper, but it is returned when TrueType, other outline-based fonts, and vector fonts are enumerated.
Windows 95/98/Me: This value is used to map vector fonts, and is returned when TrueType or vector fonts are enumerated.

OUT_TT_ONLY_PRECIS Instructs the font mapper to choose from only TrueType fonts. If there are no TrueType fonts installed in the system, the font mapper returns to default behavior.
OUT_TT_PRECIS Instructs the font mapper to choose a TrueType font when the system contains multiple fonts with the same name.


Applications can use the OUT_DEVICE_PRECIS, OUT_RASTER_PRECIS, OUT_TT_PRECIS, and OUT_PS_ONLY_PRECIS values to control how the font mapper chooses a font when the operating system contains more than one font with a specified name. For example, if an operating system contains a font named Symbol in raster and TrueType form, specifying OUT_TT_PRECIS forces the font mapper to choose the TrueType version. Specifying OUT_TT_ONLY_PRECIS forces the font mapper to choose a TrueType font, even if it must substitute a TrueType font of another name.

fdwClipPrecision
[in] Specifies the clipping precision. The clipping precision defines how to clip characters that are partially outside the clipping region. It can be one or more of the following values. Value Meaning
CLIP_CHARACTER_PRECIS Not used.
CLIP_DEFAULT_PRECIS Specifies default clipping behavior.
"directx/ CLIP_DFA_DISABLE Windows XP SP1: Turns off font association for the font. Note that this flag is not guaranteed to have any effect on any platform after Windows Server 2003.
CLIP_EMBEDDED You must specify this flag to use an embedded read-only font.
CLIP_LH_ANGLES When this value is used, the rotation for all fonts depends on whether the orientation of the coordinate system is left-handed or right-handed.
If not used, device fonts always rotate counterclockwise, but the rotation of other fonts is dependent on the orientation of the coordinate system.

For more information about the orientation of coordinate systems, see the description of the nOrientation parameter

CLIP_MASK Not used.
CLIP_DFA_OVERRIDE Windows 2000: Turns off font association for the font. This is identical to CLIP_DFA_DISABLE, but it can have problems in some situations; the recommended flag to use is CLIP_DFA_DISABLE.
CLIP_STROKE_PRECIS Not used by the font mapper, but is returned when raster, vector, or TrueType fonts are enumerated.
Windows NT/2000/XP: For compatibility, this value is always returned when enumerating fonts.

CLIP_TT_ALWAYS Not used.


fdwQuality
[in] Specifies the output quality. The output quality defines how carefully GDI must attempt to match the logical-font attributes to those of an actual physical font. It can be one of the following values. Value Meaning
ANTIALIASED_QUALITY Windows NT 4.0 and later: Font is antialiased, or smoothed, if the font supports it and the size of the font is not too small or too large.
Windows 95 with Plus!, Windows 98/Me: The display must greater than 8-bit color, it must be a single plane device, it cannot be a palette display, and it cannot be in a multiple display monitor setup. In addition, you must select a TrueType font into a screen DC prior to using it in a DIBSection, otherwise antialiasing does not happen.

CLEARTYPE_QUALITY Windows XP: If set, text is rendered (when possible) using ClearType antialiasing method. See Remarks for more information.
DEFAULT_QUALITY Appearance of the font does not matter.
DRAFT_QUALITY Appearance of the font is less important than when the PROOF_QUALITY value is used. For GDI raster fonts, scaling is enabled, which means that more font sizes are available, but the quality may be lower. Bold, italic, underline, and strikeout fonts are synthesized, if necessary.
NONANTIALIASED_QUALITY Windows 95 with Plus!, Windows 98/Me, Windows NT 4.0 and later: Font is never antialiased, that is, font smoothing is not done.
PROOF_QUALITY Character quality of the font is more important than exact matching of the logical-font attributes. For GDI raster fonts, scaling is disabled and the font closest in size is chosen. Although the chosen font size may not be mapped exactly when PROOF_QUALITY is used, the quality of the font is high and there is no distortion of appearance. Bold, italic, underline, and strikeout fonts are synthesized, if necessary.


If neither ANTIALIASED_QUALITY nor NONANTIALIASED_QUALITY is selected, the font is antialiased only if the user chooses "smooth screen fonts" in Control Panel.

fdwPitchAndFamily
[in] Specifies the pitch and family of the font. The two low-order bits specify the pitch of the font and can be one of the following values:
DEFAULT_PITCH
FIXED_PITCH
VARIABLE_PITCH
The four high-order bits specify the font family and can be one of the following values. Value Description
FF_DECORATIVE Novelty fonts. Old English is an example.
FF_DONTCARE Use default font.
FF_MODERN Fonts with constant stroke width, with or without serifs. Pica, Elite, and Courier New® are examples.
FF_ROMAN Fonts with variable stroke width and with serifs. MS® Serif is an example.
FF_SCRIPT Fonts designed to look like handwriting. Script and Cursive are examples.
FF_SWISS Fonts with variable stroke width and without serifs. MS Sans Serif is an example.



An application can specify a value for the fdwPitchAndFamily parameter by using the Boolean OR operator to join a pitch constant with a family constant.

Font families describe the look of a font in a general way. They are intended for specifying fonts when the exact typeface requested is not available.

lpszFace
[in] Pointer to a null-terminated string that specifies the typeface name of the font. The length of this string must not exceed 32 characters, including the null terminator. The EnumFontFamilies function can be used to enumerate the typeface names of all currently available fonts. For more information, see the Remarks.
If lpszFace is NULL or empty string, GDI uses the first font that matches the other specified attributes.

Return Values
If the function succeeds, the return value is a handle to a logical font.

If the function fails, the return value is NULL.

Windows NT/2000/XP: To get extended error information, call GetLastError.

Remarks
When you no longer need the font, call the DeleteObject function to delete it.

To help protect the copyrights of vendors who provide fonts for Windows, applications should always report the exact name of a selected font. Because available fonts can vary from system to system, do not assume that the selected font is always the same as the requested font. For example, if you request a font named Palatino, but no such font is available on the system, the font mapper will substitute a font that has similar attributes but a different name. Always report the name of the selected font to the user.

To get the appropriate font on different language versions of the OS, call EnumFontFamiliesEx with the desired font characteristics in the LOGFONT structure, then retrieve the appropriate typeface name and create the font using CreateFont or CreateFontIndirect.

Windows 95/98/Me, Windows NT 4.0: The fonts for many East Asian languages have two typeface names: an English name and a localized name. CreateFont, CreateFontIndirect and CreateFontIndirectEx take the localized typeface name on a system locale that matches the language, but they take the English typeface name on all other system locales. The best method is to try one name and, on failure, try the other. Note that EnumFonts, EnumFontFamilies, and EnumFontFamiliesEx return the English typeface name if the system locale does not match the language of the font.

Windows 2000/XP: The font mapper for CreateFont, CreateFontIndirect, and CreateFontIndirectEx recognizes both the English and the localized typeface name, regardless of locale.

Windows XP: The following situations do not support ClearType antialiasing:

Text rendered on a printer.
A display set for 256 colors or less.
Text rendered to a terminal server client.
The font is not a TrueType font or an OpenType font with TrueType outlines. For example, the following do not support ClearType antialiasing: Type 1 fonts, Postscript OpenType fonts without TrueType outlines, bitmap fonts, vector fonts, and device fonts .
The font has tuned embedded bitmaps, only for the font sizes that contain the embedded bitmaps. For example, this occurs commonly in East Asian fonts.
Windows 95/98/Me: CreateFontW is supported by the Microsoft Layer for Unicode. To use this, you must add certain files to your application, as outlined in Microsoft Layer for Unicode on Windows 95/98/Me Systems.

Example Code
For an example, see "Setting Fonts for Menu-Item Text Strings" in Using Menus.
