GlyphMetrics Struct
Holds all of the various metrics of a glyph for rendering purposes.
public readonly struct GlyphMetrics :
System.IEquatable<Velaptor.Graphics.GlyphMetrics>
Implements System.IEquatable<GlyphMetrics>
Properties
Ascender
Gets the vertical distance from the horizontal baseline to the highest 'character'
coordinate in a font face.
public float Ascender { get; set; }
Property Value
Remarks
Unfortunately, font formats don't define the ascender in a
uniform way. For some formats, it represents the ascent of all capital Latin characters
(without accents). For others it is the ascent of the highest accented character. Finally,
other formats define it as being equal to Y max value of the global bounding box.
CharIndex
Gets the glyph index.
public uint CharIndex { get; set; }
Property Value
Remarks
The value of 0 means ‘undefined character code’.
Descender
Gets the vertical distance from the horizontal baseline to the lowest ‘character’ coordinate in a font face.
public float Descender { get; set; }
Property Value
Remarks
Unfortunately, font formats don't define the descender in a uniform way. For some formats,
it represents the descent of all capital Latin characters (without accents). For others it is
the ascent of the lowest accented character. Finally, other formats define it as being equal
to the Y min value of the global bounding box. This field is negative for values below the baseline.
Glyph
Gets the glyph character.
public char Glyph { get; set; }
Property Value
GlyphBounds
Gets the rectangular bounds of where in a font texture
atlas the given Glyph resides.
public System.Drawing.RectangleF GlyphBounds { get; set; }
Property Value
GlyphHeight
Gets the glyph's height.
public float GlyphHeight { get; set; }
Property Value
GlyphWidth
Gets the glyph's width.
public float GlyphWidth { get; set; }
Property Value
HoriBearingX
Gets the horizontal distance from the current cursor position to
the leftmost border of the glyph image's bounding box.
public float HoriBearingX { get; set; }
Property Value
HoriBearingY
Gets the vertical distance from the current cursor position
(on the baseline) to the top most border of the glyph image's bounding box.
public float HoriBearingY { get; set; }
Property Value
HorizontalAdvance
Gets the horizontal distance to increment the pen position when the glyph
is drawn as part of a string of text.
public float HorizontalAdvance { get; set; }
Property Value
XMax
Gets the horizontal maximum (right-most).
public float XMax { get; set; }
Property Value
XMin
Gets the horizontal minimum (left-most).
public float XMin { get; set; }
Property Value
YMax
Gets the vertical maximum (top-most).
public float YMax { get; set; }
Property Value
YMin
Gets the vertical minimum (bottom-most).
public float YMin { get; set; }
