The OUTLINETEXTMETRIC structure contains metrics describing a TrueType font.
otmSize
Specifies the size, in bytes, of the OUTLINETEXTMETRIC structure.
otmTextMetrics
Specifies a TEXTMETRIC structure containing further information about the font.
otmFiller
Specifies a value that causes the structure to be byte-aligned.
otmPanoseNumber
Specifies the Panose number for this font.
otmfsSelection
Specifies the nature of the font pattern. This member can be a combination of the following bits:
| Bit | Meaning |
| 0 | Italic |
| 1 | Underscore |
| 2 | Negative |
| 3 | Outline |
| 4 | Strikeout |
| 5 | Bold |
otmfsType
Specifies whether the font is licensed. Licensed fonts may not be modified or exchanged. If bit 1 is set, the font may not be embedded in a document. If bit 1 is clear, the font can be embedded. If bit 2 is set, the embedding is read-only.
otmsCharSlopeRise
Specifies the slope of the cursor. This value is 1 if the slope is vertical. Applications can use this value and the value of the otmsCharSlopeRun member to create an italic cursor that has the same slope as the main italic angle (specified by the otmItalicAngle member).
otmsCharSlopeRun
Specifies the slope of the cursor. This value is zero if the slope is vertical. Applications can use this value and the value of the otmsCharSlopeRise member to create an italic cursor that has the same slope as the main italic angle (specified by the otmItalicAngle member).
otmItalicAngle
Specifies the main italic angle of the font, in counterclockwise degrees from vertical. Regular (roman) fonts have a value of zero. Italic fonts typically have a negative italic angle (that is, they lean to the right).
otmEMSquare
Specifies the number of logical units defining the x- or y-dimension of the em square for this font. (The number of units in the x- and y-directions are always the same for an em square.)
otmAscent
Specifies the maximum distance characters in this font extend above the base line. This is the typographic ascent for the font.
otmDescent
Specifies the maximum distance characters in this font extend below the base line. This is the typographic descent for the font.
otmLineGap
Specifies typographic line spacing.
otmsXHeight
Not supported.
otmsCapEmHeight
Not supported.
otmrcFontBox
Specifies the bounding box for the font.
otmMacAscent
Specifies the maximum distance characters in this font extend above the base line for the Macintosh.
otmMacDescent
Specifies the maximum distance characters in this font extend below the base line for the Macintosh.
otmMacLineGap
Specifies line-spacing information for the Macintosh.
otmusMinimumPPEM
Specifies the smallest recommended size for this font, in pixels per em-square.
otmptSubscriptSize
Specifies the recommended horizontal and vertical size for subscripts in this font.
otmptSubscriptOffset
Specifies the recommended horizontal and vertical offset for subscripts in this font. The subscript offset is measured from the character origin to the origin of the subscript character.
otmptSuperscriptSize
Specifies the recommended horizontal and vertical size for superscripts in this font.
otmptSuperscriptOffset
Specifies the recommended horizontal and vertical offset for superscripts in this font. The subscript offset is measured from the character base line to the base line of the superscript character.
otmsStrikeoutSize
Specifies the width of the strikeout stroke for this font. Typically, this is the width of the em-dash for the font.
otmsStrikeoutPosition
Specifies the position of the strikeout stroke relative to the base line for this font. Positive values are above the base line and negative values are below.
otmsUnderscorePosition
Specifies the position of the underscore character for this font.
otmsUnderscoreSize
Specifies the thickness of the underscore character for this font.
otmpFamilyName
Specifies the offset from the beginning of the structure to a string specifying the family name for the font.
otmpFaceName
Specifies the offset from the beginning of the structure to a string specifying the face name for the font. (This face name corresponds to the name specified in the LOGFONT structure.)
otmpStyleName
Specifies the offset from the beginning of the structure to a string specifying the style name for the font.
otmpFullName
Specifies the offset from the beginning of the structure to a string specifying the full name for the font. This name is unique for the font and often contains a version number or other identifying information.
The sizes returned in OUTLINETEXTMETRIC are given in logical units; that is, they depend on the current mapping mode of the specified display context.
