Syntax

public class GdiFontMetrics

Fields

GDI_ERROR

Declaration
public const long GDI_ERROR = 4294967295L
Field Value
System.Int64

Properties

AnsiKerningPairs

Gets a collection of kerning pairs for characters defined in the WinAnsiEncoding scheme only.

Declaration
public GdiKerningPairs AnsiKerningPairs { get; }
Property Value
GdiKerningPairs

Ascent

Specifies the maximum distance characters in this font extend above the base line. This is the typographic ascent for the font.

Declaration
public int Ascent { get; }
Property Value
System.Int32

AverageWidth

Gets the average width of glyphs in a font.

Declaration
public int AverageWidth { get; }
Property Value
System.Int32

BoundingBox

Gets the font's bounding box.

Declaration
public int[] BoundingBox { get; }
Property Value
System.Int32[]

Remarks

This is the smallest rectangle enclosing the shape that would result if all the glyphs of the font were placed with their origins cooincident and then filled.

CapHeight

Gets the distance between the baseline and the approximate height of uppercase letters.

Declaration
public int CapHeight { get; }
Property Value
System.Int32

Descent

Specifies the maximum distance characters in this font extend below the base line. This is the typographic descent for the font.

Declaration
public int Descent { get; }
Property Value
System.Int32

EmSquare

Specifies the number of logical units defining the x- or y-dimension of the em square for this font. The common value for EmSquare is 2048.

Declaration
public int EmSquare { get; }
Property Value
System.Int32

Remarks

The number of units in the x- and y-directions are always the same for an em square.)

FaceName

Retrieves the typeface name of the font that is selected into the device context supplied to the GdiFontMetrics constructor.

Declaration
public string FaceName { get; }
Property Value
System.String

FirstChar

Gets the value of the first character defined in the font

Declaration
public int FirstChar { get; }
Property Value
System.Int32

Flags

Gets a collection of flags defining various characteristics of a font (e.g. serif or sans-serif, symbolic, etc).

Declaration
public int Flags { get; }
Property Value
System.Int32

IsEmbeddable

Gets a value indicating whether the font can be legally embedded within a document.

Declaration
public bool IsEmbeddable { get; }
Property Value
System.Boolean

IsSubsettable

Gets a value indicating whether the font can be legally subsetted.

Declaration
public bool IsSubsettable { get; }
Property Value
System.Boolean

ItalicAngle

Gets the main italic angle of the font expressed in tenths of a degree counterclockwise from the vertical.

Declaration
public int ItalicAngle { get; }
Property Value
System.Int32

Remarks

Regular (roman) fonts have a value of zero. Italic fonts typically have a negative italic angle (that is, they lean to the right).

KerningPairs

Gets a collection of kerning pairs.

Declaration
public GdiKerningPairs KerningPairs { get; }
Property Value
GdiKerningPairs

LastChar

Gets the value of the last character defined in the font

Declaration
public int LastChar { get; }
Property Value
System.Int32

MaxWidth

Gets the maximum width of glyphs in a font.

Declaration
public int MaxWidth { get; }
Property Value
System.Int32

StemV

TODO: The thickness, measured horizontally, of the dominant vertical stems of the glyphs in the font.

Declaration
public int StemV { get; }
Property Value
System.Int32

XHeight

Gets the distance between the baseline and the approximate height of non-ascending lowercase letters.

Declaration
public int XHeight { get; }
Property Value
System.Int32

Methods
