SkFont controls options applied when drawing and measuring text.
Whether edge pixels draw opaque or with partial transparency.
incomplete
Amount of font hinting applied to glyph outlines.
incomplete
Constructs SkFont with default values.
default initialized SkFont
incomplete
Constructs SkFont with default values with SkTypeface and size in points.
initialized SkFont
incomplete
Constructs SkFont with default values with SkTypeface and size in points, horizontal scale, and horizontal skew. Horizontal scale emulates condensed and expanded fonts. Horizontal skew emulates oblique fonts.
initialized SkFont
incomplete
Compares SkFont and font, and returns true if they are equivalent. May return false if SkTypeface has identical contents but different pointers.
true if SkFont pair are equivalent
incomplete
If true, instructs the font manager to always hint glyphs. Returned value is only meaningful if platform uses FreeType as the font manager.
true if all glyphs are hinted
incomplete
Returns true if font engine may return glyphs from font bitmaps instead of from outlines.
true if glyphs may be font bitmaps
incomplete
Returns true if glyphs at different sub-pixel positions may differ on pixel edge coverage.
true if glyph positioned in pixel using transparency
incomplete
Returns true if text is converted to SkPath before drawing and measuring.
true glyph hints are never applied
incomplete
Returns true if bold is approximated by increasing the stroke width when creating glyph bitmaps from outlines.
bold is approximated through stroke width
incomplete
Sets whether to always hint glyphs. If forceAutoHinting is set, instructs the font manager to always hint glyphs.
Only affects platforms that use FreeType as the font manager.
incomplete
Requests, but does not require, to use bitmaps in fonts instead of outlines.
incomplete
Requests, but does not require, that glyphs respect sub-pixel positioning.
incomplete
Requests, but does not require, that glyphs are converted to SkPath before drawing and measuring.
incomplete
Increases stroke width when creating glyph bitmaps to approximate a bold typeface.
incomplete
Whether edge pixels draw opaque or with partial transparency.
one of: Edging::kAlias, Edging::kAntiAlias, Edging::kSubpixelAntiAlias
incomplete
Requests, but does not require, that edge pixels draw opaque or with partial transparency.
incomplete
Sets level of glyph outline adjustment. Does not check for valid values of hintingLevel.
SkFontHinting::kNormal, SkFontHinting::kFull
incomplete
Returns level of glyph outline adjustment.
one of: SkFontHinting::kNone, SkFontHinting::kSlight, SkFontHinting::kNormal,
SkFontHinting::kFull
incomplete
Returns a font with the same attributes of this font, but with the specified size. Returns nullptr if size is less than zero, infinite, or NaN.
initialized SkFont
incomplete
Returns SkTypeface if set, or nullptr. Does not alter SkTypeface SkRefCnt.
SkTypeface if previously set, nullptr otherwise
incomplete
Returns text size in points.
typographic height of text
incomplete
Returns text scale on x-axis. Default value is 1.
text horizontal scale
incomplete
Returns text skew on x-axis. Default value is zero.
additional shear on x-axis relative to y-axis
incomplete
Increases SkTypeface SkRefCnt by one.
SkTypeface if previously set, nullptr otherwise
incomplete
Sets SkTypeface to typeface, decreasing SkRefCnt of the previous SkTypeface. Pass nullptr to clear SkTypeface and use the default typeface. Increments tf SkRefCnt by one.
incomplete
Sets text size in points. Has no effect if textSize is not greater than or equal to zero.
incomplete
Sets text scale on x-axis. Default value is 1.
incomplete
Sets text skew on x-axis. Default value is zero.
incomplete
Converts text into glyph indices. Returns the number of glyph indices represented by text. SkTextEncoding specifies how text represents characters or glyphs. glyphs may be nullptr, to compute the glyph count.
Does not check text for valid character codes or valid glyph indices.
If byteLength equals zero, returns zero. If byteLength includes a partial character, the partial character is ignored.
If encoding is kUTF8_SkTextEncoding and text contains an invalid UTF-8 sequence, zero is returned.
If maxGlyphCount is not sufficient to store all the glyphs, no glyphs are copied. The total glyph count is returned for subsequent buffer reallocation.
kUTF32_SkTextEncoding, kGlyphID_SkTextEncoding
number of glyphs represented by text of length byteLength
incomplete
Returns glyph index for Unicode character.
glyph index
incomplete
Returns number of glyphs represented by text.
kUTF32_SkTextEncoding, kGlyphID_SkTextEncoding
number of glyphs represented by text of length byteLength
incomplete
Returns true if all text corresponds to a non-zero glyph index. Returns false if any characters in text are not supported in SkTypeface.
If SkTextEncoding is kGlyphID_SkTextEncoding, returns true if all glyph indices in text are non-zero; does not check to see if text contains valid glyph indices for SkTypeface.
Returns true if byteLength is zero.
true if all text corresponds to a non-zero glyph index
incomplete
Returns the advance width of text. The advance is the normal distance to move before drawing additional text. Returns the bounding box of text if bounds is not nullptr.
kUTF32_SkTextEncoding, kGlyphID_SkTextEncoding
number of glyphs represented by text of length byteLength
incomplete
Returns path corresponding to glyph outline. If glyph has an outline, copies outline to path and returns true. path returned may be empty. If glyph is described by a bitmap, returns false and ignores path parameter.
true if glyphID is described by path
incomplete
Returns path corresponding to glyph array.
incomplete
Returns SkFontMetrics associated with SkTypeface. The return value is the recommended spacing between lines: the sum of metrics descent, ascent, and leading. If metrics is not nullptr, SkFontMetrics is copied to metrics. Results are scaled by text size but does not take into account dimensions required by text scale, text skew, fake bold, style stroke, and SkPathEffect.
recommended spacing between lines
incomplete
Returns the recommended spacing between lines: the sum of metrics descent, ascent, and leading. Result is scaled by text size but does not take into account dimensions required by stroking and SkPathEffect. Returns the same result as getMetrics().
