GLYPH_FLAG_UNSAFE_TO_BREAK: Indicates that if input text is broken at the * beginning of the cluster this glyph is part of, * then both sides need to be re-shaped, as the * result might be different. On the flip side, * it means that when this flag is not present, * then it's safe to break the glyph-run at the * beginning of this cluster, and the two sides * represent the exact same result one would get * if breaking input text at the beginning of * this cluster and shaping the two sides * separately. This can be used to optimize * paragraph layout, by avoiding re-shaping * of each line after line-breaking, or limiting * the reshaping to a small piece around the * breaking point only.

Types

type Buffer 

type Buffer struct {
	Input             string
	SegmentProperties // properties for the whole buffer by default
	BufferFlags
	ClusterLevel
	Segments []Segment
}

*

  • Buffer holds the input text and its properties before shaping.

func (*Buffer) GuessSegmentProperties 

func (bufer *Buffer) GuessSegmentProperties() error

Tries to split the buffer in segments and guess their properties, based on the text in the buffer.

func (Buffer) IsFlag 

func (buffer Buffer) IsFlag(flag BufferFlags) bool

func (*Buffer) Reset 

func (buffer *Buffer) Reset()

func (*Buffer) SetFlag 

func (buffer *Buffer) SetFlag(flag BufferFlags)

type BufferFlags 

type BufferFlags uint

type ClusterLevel 

type ClusterLevel int

type Color 

type Color = color.RGBA

Color is the data type for type for holding color values. * It is simply an alias for image/color.RGBA

func NewColor 

func NewColor(b, g, r, a uint8) Color

Creates a new color. Note that the creation order is b g r a because that is what HarfBuzz uses.

type Direction 

type Direction uint8

func DirectionFromString 

func DirectionFromString(s string) Direction

func (Direction) IsHorizontal 

func (d Direction) IsHorizontal() bool

func (Direction) IsVertical 

func (d Direction) IsVertical() bool

type Drawer 

type Drawer interface {
	// Moves the pen of the drawer to the given position without drawing
	MoveTo(toX, toY Position)
	// Draws a straight line to the target points, moving the pen.
	LineTo(toX, toY Position)
	// Draws a quadratic line to the target points, moving the pen.
	QuadraticTo(controlX, controlY, toX, toY Position)
	// Draws a cubic line to the target points, moving the pen.
	CubicTo(control1X, control1Y, control2X, control2Y, toX, toY Position)
	// Closes the path. The path begins at the first time the drawer is called,
	// and at any call to colosepath. The closed path may be filled.
	ClosePath()
}

Interface for user supplied drawing. The drawing will need to keep the state of the last point drawn to by itself.

type Face 

type Face struct {
	font.Face
}

func (*Face) LayoutFeatureTypes 

func (face *Face) LayoutFeatureTypes() []LayoutFeatureType

func (*Face) LayoutHasPositioning 

func (face *Face) LayoutHasPositioning() bool

func (*Face) LayoutHasSubstitution 

func (face *Face) LayoutHasSubstitution() bool

func (*Face) LayoutHasTracking 

func (face *Face) LayoutHasTracking() bool

func (*Face) SelectorInfos 

func (face *Face) SelectorInfos() []LayoutFeatureSelectorInfo

type Feature 

type Feature struct {
	Tag
	Value uint32
	Start int
	End   int
}

Feature is the structure that holds information about requested * feature application. The feature will be applied with the given value to all * glyphs which are in clusters between start (inclusive) and end (exclusive). * Setting start to FEATURE_GLOBAL_START and end to FEATURE_GLOBAL_END * specifies that the feature always applies to the entire buffer.

type Font 

type Font struct {
	sfnt.Font
}

A font, based on golang.org/x/image/sfnt.Font

type GlyphInfo 

type GlyphInfo struct {
	Codepoint rune
	Cluster   uint32
	// contains filtered or unexported fields
}

GlyphInfo contains information about the glyphs and their relation * to input text. * @codepoint: either a Unicode code point (before shaping) or a glyph index * (after shaping). * @cluster: the index of the character in the original text that corresponds * to this GlyphInfo, or whatever the client passes to * hb_buffer_add(). More than one #GlyphInfo can have the same * @cluster value, if they resulted from the same character (e.g. one * to many glyph substitution), and when more than one character gets * merged in the same glyph (e.g. many to one glyph substitution) the * #GlyphInfo will have the smallest cluster value of them. * By default some characters are merged into the same cluster * (e.g. combining marks have the same cluster as their bases) * even if they are separate glyphs, hb_buffer_set_cluster_level() * allow selecting more fine-grained cluster handling.

func (*GlyphInfo) IsFlag 

func (info *GlyphInfo) IsFlag(flag uint64) bool

func (*GlyphInfo) SetFlag 

func (info *GlyphInfo) SetFlag(flag uint64)

func (*GlyphInfo) UnsafeToBreak 

func (info *GlyphInfo) UnsafeToBreak() bool

type GlyphPosition 

type GlyphPosition struct {
	XAdvance Position
	YAdvance Position
	XOffset  Position
	YOffset  Position
	// contains filtered or unexported fields
}

*

  • GlyphPosition:
  • XAdvance: how much the line advances after drawing this glyph when setting
  • text in horizontal direction.
  • YAdvance: how much the line advances after drawing this glyph when setting
  • text in vertical direction.
  • XOffset: how much the glyph moves on the X-axis before drawing it, this
  • should not affect how much the line advances.
  • YOffset: how much the glyph moves on the Y-axis before drawing it, this
  • should not affect how much the line advances. *
  • GlyphPosition holds the positions of the
  • glyph in both horizontal and vertical directions. All positions in *
  • GlyphPosition are relative to the current point. *

type Language 

type Language struct {
	language.Tag
}

type LayoutFeatureSelector 

type LayoutFeatureSelector uint16

type LayoutFeatureSelectorInfo 

type LayoutFeatureSelectorInfo struct {
	Name    string
	Enable  LayoutFeatureSelector
	Disable LayoutFeatureSelector
	// contains filtered or unexported fields
}

type LayoutFeatureType 

type LayoutFeatureType uint16

func (LayoutFeatureType) Name 

func (lft LayoutFeatureType) Name() string

type Mask 

type Mask uint32

type Position 

type Position int32

type Script 

type Script struct {

	Range []unicode.RangeTable
}

type Segment 

type Segment struct {
	SegmentProperties

	End   int64
}

Segment is a segment of text with uniform language, direction and script *

type SegmentProperties 

type SegmentProperties struct {
	Direction
	Script
	Language
}

*

  • SegmentProperties:
  • @direction: the #hb_direction_t of the buffer, see hb_buffer_set_direction().
  • @script: the #hb_script_t of the buffer, see hb_buffer_set_script().
  • @language: the #hb_language_t of the buffer, see hb_buffer_set_language().
  • SegmentProperties holds various text properties of a Buffer. Can be
  • set and retrieved using SetSegmentProperties() and
  • GetSegmentProperties(), respectively.

type Tag 

type Tag string

Unlike in HarfBuzz, tags are simply strings, which they should be, in stead of a 4 character string squeezed into a uint32.

type Variation 

type Variation struct {
	Tag
	Value float32
}
