Struct DWriteGlyphRun

The DWRITE_GLYPH_RUN structure contains the information needed by renderers to draw glyph runs. All coordinates are in device independent pixels (DIPs).

DWriteGlyphRun(nint, float, ushort[], float[], DWriteGlyphOffset[], bool, uint)

Declaration
public DWriteGlyphRun(nint fontFace, float fontEMSize, ushort[] indices, float[] advances, DWriteGlyphOffset[] offsets, bool isSideways, uint bidiLevel)
Parameters
Type Name Description
nint fontFace
float fontEMSize
ushort[] indices
float[] advances
DWriteGlyphOffset[] offsets
bool isSideways
uint bidiLevel

Properties

BidiLevel

Gets or sets the implicit resolved bidi level of the run. Odd levels indicate right-to-left languages like Hebrew and Arabic, while even levels indicate left-to-right languages like English and Japanese (when written horizontally). For right-to-left languages, the text origin is on the right, and text should be drawn to the left.

Declaration
public uint BidiLevel { get; set; }
Property Value
Type Description
uint

FontEMSize

Gets or sets the logical size of the font in DIPs, not points (equals 1/96 inch).

Declaration
public float FontEMSize { get; set; }
Property Value
Type Description
float

Property Value
Type Description
nint

IsSideways

Gets or sets a value indicating whether glyphs are rotated 90 degrees to the left and vertical metrics are used. Vertical writing is achieved by specifying isSideways = true and rotating the entire run 90 degrees to the right via a rotate transform.

Declaration
public bool IsSideways { get; set; }
Property Value
Type Description
bool
