Description & Usage
The TEXTMETRIC structure holds the text metrics of a font. The structure describes many physical attributes of the font. Unless otherwise specified, all size measurements of the font stored in the structure are in the logical units of the device the font is being used on, so the same font may have a different "scale" if used on a different device.
Visual Basic-Specific Issues
None.
Data Members
- tmHeight
- The height of the font's characters (equal to the sum of tmAscent and tmDescent).
- tmAscent
- The ascent (units above the base line) of the font's characters.
- tmDescent
- The descent (units below the base line) of the font's characters.
- tmInternalLeading
- The amount of leading space inside the bounds of tmHeight where accent marks or other diacritical marks may appear.
- tmExternalLeading
- The amount of leading space placed between rows of text in which the font does not draw.
- tmAveCharWidth
- The average width of the font's characters, usually identified as the width of the "x" character. This value does not include extra space required for bold or italic characters.
- tmMaxCharWidth
- The width of the widest character of the font. This value does not include extra space required for bold or italics.
- tmWeight
- One of the following flags specifying the boldness (weight) of the font:
- FW_DONTCARE
- Default weight.
- FW_THIN
- Thin weight.
- FW_EXTRALIGHT
- Extra-light weight.
- FW_ULTRALIGHT
- Same as FW_EXTRALIGHT.
- FW_LIGHT
- Light weight.
- FW_NORMAL
- Normal weight.
- FW_REGULAR
- Same as FW_NORMAL.
- FW_MEDIUM
- Medium weight.
- FW_SEMIBOLD
- Semi-bold weight.
- FW_DEMIBOLD
- Same As FW_SEMIBOLD.
- FW_BOLD
- Bold weight.
- FW_EXTRABOLD
- Extra-bold weight.
- FW_ULTRABOLD
- Same as FW_EXTRABOLD.
- FW_HEAVY
- Heavy weight.
- FW_BLACK
- Same as FW_HEAVY.
- tmOverhang
- The extra width per string added to the font when synthesizing attributes such as boldface and italics. For a boldface effect, this is the distance by which the overstrike is offset. For an italics effect, this is the amount that the top of the character is sheared past the bottom of the character.
- tmDigitizedAspectX
- The horizontal aspect of the device for which the font was designed.
- tmDigitizedAspectY
- The vertical aspect of the device for which the font was designed.
- tmFirstChar
- The value of the first character defined in the font.
- tmLastChar
- The value of the last character defined in the font.
- tmDefaultChar
- The value of the character to substitute for characters not present in the font.
- tmBreakChar
- The value of the character to be used for work breaks for text justification.
- tmItalic
- If zero, the font is not an italic font. If a non-zero value, the font is an italic font.
- tmUnderlined
- If zero, the font is not an underlined font. If a non-zero value, the font is an underlined font.
- tmStruckOut
- If zero, the font is not a strikeout font. If a non-zero value, the font is a strikeout font.
- tmPitchAndFamily
- A bitwise OR combination of exactly one *_PITCH flag specifying the pitch of the font and exactly one FF_* flag specifying the font face family of the font:
- DEFAULT_PITCH
- The default pitch.
- FIXED_PITCH
- Fixed pitch.
- VARIABLE_PITCH
- Variable pitch.
- FF_DECORATIVE
- Showy, decorative font face.
- FF_DONTCARE
- Do not care about the font face.
- FF_MODERN
- Modern font face (monospaced, sans serif font).
- FF_ROMAN
- Roman font face (proportional-width, serif font).
- FF_SCRIPT
- Script font face which imitates script handwriting.
- FF_SWISS
- Swiss font face (proportional-width, sans serif font).
- tmCharSet
- One of the following flags identifying the character set of the font:
- ANSI_CHARSET
- ANSI character set.
- ARABIC_CHARSET
- Windows NT, 2000: Arabic character set.
- BALTIC_CHARSET
- Windows 95, 98: Baltic character set.
- CHINESEBIG5_CHARSET
- Chinese Big 5 character set.
- DEFAULT_CHARSET
- Default character set.
- EASTEUROPE_CHARSET
- Windows 95, 98: Eastern European character set.
- GB2312_CHARSET
- GB2312 character set.
- GREEK_CHARSET
- Windows 95, 98: Greek character set.
- HANGEUL_CHARSET
- HANDEUL character set.
- HEBREW_CHARSET
- Windows NT, 2000: Hebrew character set.
- JOHAB_CHARSET
- Windows 95, 98: Johab character set.
- MAC_CHARSET
- Windows 95, 98: Mac character set.
- OEM_CHARSET
- Original equipment manufacturer (OEM) character set.
- RUSSIAN_CHARSET
- Windows 95, 98: Russian character set.
- SHIFTJIS_CHARSET
- ShiftJis character set.
- SYMBOL_CHARSET
- Symbol character set.
- THAI_CHARSET
- Windows NT, 2000: Thai character set.
- TURKISH_CHARSET
- Windows 95, 98: Turkish character set.
