class <a href='SkFont_Reference#SkFont'>SkFont</a> {
    // <i><a href='SkFont_Reference#SkFont'>SkFont</a> interface</i>
};
</pre>

<a name='Advance'></a>

<a name='Engine'></a>

<a name='Size'></a>

<a href='#Font_Size'>Font_Size</a> adjusts the overall <a href='undocumented#Text'>text</a> <a href='undocumented#Size'>size</a> in <a href='SkPoint_Reference#Point'>points</a>.
<a href='#Font_Size'>Font_Size</a> can be set to any positive value or zero.
<a href='#Font_Size'>Font_Size</a> defaults to 12.
<a href='#Font_Size'>Font_Size</a>

<a name='Scale_X'></a>

<a href='#Font_Scale_X'>Font_Scale_X</a> adjusts the <a href='undocumented#Text'>text</a> horizontal scale.
<a href='undocumented#Text'>Text</a> scaling approximates condensed and expanded type faces when the actual face
is not available.
<a href='#Font_Scale_X'>Font_Scale_X</a> can be set to any value.
<a href='#Font_Scale_X'>Font_Scale_X</a> defaults to 1.

<a name='Skew_X'></a>

<a href='#Font_Skew_X'>Font_Skew_X</a> adjusts the <a href='undocumented#Text'>text</a> horizontal slant.
<a href='undocumented#Text'>Text</a> skewing approximates italic and oblique type faces when the actual face
is not available.
<a href='#Font_Skew_X'>Font_Skew_X</a> can be set to any value.
<a href='#Font_Skew_X'>Font_Skew_X</a> defaults to 0.

<a name='Embolden'></a>

<a href='#Font_Embolden'>Font_Embolden</a> approximates the bold <a href='SkFont_Reference#Font'>font</a> style accompanying a normal <a href='SkFont_Reference#Font'>font</a> when a bold <a href='SkFont_Reference#Font'>font</a> face
is not available. Skia does not provide <a href='SkFont_Reference#Font'>font</a> substitution; it is up to the client to find the
bold <a href='SkFont_Reference#Font'>font</a> face using the platform <a href='#Font_Manager'>Font_Manager</a>.

Use <a href='#Font_Skew_X'>Font_Skew_X</a> to approximate an italic <a href='SkFont_Reference#Font'>font</a> style when the italic <a href='SkFont_Reference#Font'>font</a> face
is not available.

A FreeType based port may define SK_USE_FREETYPE_EMBOLDEN at compile time to direct
the  <a href='SkFont_Reference#Font_Engine'>font engine</a> to create the bold <a href='undocumented#Glyph'>Glyphs</a>. Otherwise, the extra bold is computed
by increasing the stroke width and setting the <a href='SkPaint_Reference#SkPaint'>SkPaint</a>::<a href='#SkPaint_Style'>Style</a> to
<a href='SkPaint_Reference#SkPaint'>SkPaint</a>::<a href='#SkPaint_kStrokeAndFill_Style'>kStrokeAndFill_Style</a> as needed.

<a href='#Font_Embolden'>Font_Embolden</a> is disabled by default.

<a name='Hinting_Spacing'></a>

If Hinting is set to <a href='undocumented#SkFontHinting'>SkFontHinting</a>::<a href='#SkFontHinting_kFull'>kFull</a>, <a href='#Font_Hinting_Spacing'>Hinting_Spacing</a> adjusts the character
spacing by the difference of the hinted and unhinted <a href='#Left_Side_Bearing'>Left_Side_Bearing</a> and
<a href='#Right_Side_Bearing'>Right_Side_Bearing</a>. <a href='#Font_Hinting_Spacing'>Hinting_Spacing</a> only applies to platforms that use
FreeType as their <a href='#Font_Engine'>Font_Engine</a>.

<a href='#Font_Hinting_Spacing'>Hinting_Spacing</a> is not related to <a href='undocumented#Text'>text</a> kerning, where the space between
a specific pair of characters is adjusted using <a href='undocumented#Data'>data</a> in the <a href='SkFont_Reference#Font'>font</a> kerning tables.

<a name='Linear'></a>

<a href='#Font_Linear'>Font_Linear</a> selects whether <a href='undocumented#Text'>text</a> is rendered as a <a href='undocumented#Glyph'>Glyph</a> or as a <a href='SkPath_Reference#Path'>Path</a>.
If <a href='#Font_Linear'>Font_Linear</a> is set, it has the same effect as setting Hinting to <a href='undocumented#SkFontHinting'>SkFontHinting</a>::<a href='#SkFontHinting_kNormal'>kNormal</a>.
If <a href='#Font_Linear'>Font_Linear</a> is clear, it is the same as setting Hinting to <a href='undocumented#SkFontHinting'>SkFontHinting</a>::<a href='#SkFontHinting_kNone'>kNone</a>.

<a name='Subpixel'></a>

<a href='#Font_Subpixel'>Font_Subpixel</a> uses the <a href='undocumented#Pixel'>pixel</a> transparency to represent a fractional offset.
As the opaqueness of the <a href='SkColor_Reference#Color'>color</a> increases, the edge of the <a href='undocumented#Glyph'>glyph</a> appears to move
towards the outside of the <a href='undocumented#Pixel'>pixel</a>.

<a name='Anti_Alias'></a>

When set, <a href='#Paint_Anti_Alias'>Anti_Alias</a> positions <a href='undocumented#Glyph'>glyphs</a> within a <a href='undocumented#Pixel'>pixel</a>, using <a href='SkColor_Reference#Alpha'>alpha</a> and
possibly RGB striping. It can take advantage of the organization of RGB stripes
that create a <a href='SkColor_Reference#Color'>color</a>, and relies on the small <a href='undocumented#Size'>size</a> of the stripe and visual perception
to make the <a href='SkColor_Reference#Color'>color</a> fringing imperceptible.

<a href='#Paint_Anti_Alias'>Anti_Alias</a> can be enabled on devices that orient stripes horizontally
or vertically, and that order the <a href='SkColor_Reference#Color'>color</a> components as RGB or BGR. Internally, the
<a href='undocumented#Glyph'>glyph</a> cache may store multiple copies of the same <a href='undocumented#Glyph'>glyph</a> with different <a href='SkFont_Reference#Subpixel'>sub-pixel</a>
positions, requiring more memory.

<a name='Force_Hinting'></a>

If Hinting is set to <a href='undocumented#SkFontHinting'>SkFontHinting</a>::<a href='#SkFontHinting_kNormal'>kNormal</a> or <a href='undocumented#SkFontHinting'>SkFontHinting</a>::<a href='#SkFontHinting_kFull'>kFull</a>, <a href='#Font_Force_Hinting'>Force_Hinting</a>
instructs the <a href='#Font_Manager'>Font_Manager</a> to always hint <a href='undocumented#Glyph'>Glyphs</a>.
<a href='#Font_Force_Hinting'>Force_Hinting</a> has no effect if Hinting is set to <a href='undocumented#SkFontHinting'>SkFontHinting</a>::<a href='#SkFontHinting_kNone'>kNone</a> or
<a href='undocumented#SkFontHinting'>SkFontHinting</a>::<a href='#SkFontHinting_kSlight'>kSlight</a>.

<a href='#Font_Force_Hinting'>Force_Hinting</a> only affects platforms that use FreeType as the <a href='#Font_Manager'>Font_Manager</a>.

<a name='Embedded_Bitmaps'></a>

<a href='#Font_Embedded_Bitmaps'>Embedded_Bitmaps</a> allows selecting custom sized <a href='SkBitmap_Reference#Bitmap'>bitmap</a> <a href='undocumented#Glyph'>Glyphs</a>.
<a href='#Font_Embedded_Bitmaps'>Embedded_Bitmaps</a> when set chooses an embedded <a href='SkBitmap_Reference#Bitmap'>bitmap</a> <a href='undocumented#Glyph'>glyph</a> over an outline contained
in a <a href='SkFont_Reference#Font'>font</a> if the platform supports this option.

FreeType selects the <a href='SkBitmap_Reference#Bitmap'>bitmap</a> <a href='undocumented#Glyph'>glyph</a> if available when <a href='#Font_Embedded_Bitmaps'>Embedded_Bitmaps</a> is set, and selects
the outline <a href='undocumented#Glyph'>glyph</a> if <a href='#Font_Embedded_Bitmaps'>Embedded_Bitmaps</a> is clear.
Windows may select the <a href='SkBitmap_Reference#Bitmap'>bitmap</a> <a href='undocumented#Glyph'>glyph</a> but is not required to do so.
<a href='#OS_X'>OS_X</a> and iOS do not support this option.

Returns the bytes of <a href='#SkFont_breakText_text'>text</a> that fit within <a href='#SkFont_breakText_maxWidth'>maxWidth</a>.
The <a href='#SkFont_breakText_text'>text</a> fragment fits if its advance width is less than or equal to <a href='#SkFont_breakText_maxWidth'>maxWidth</a>.
