< a href = '#Paint' > Paint< / a > controls options applied when drawing and measuring. < a href = '#Paint' > Paint< / a > collects all
options outside of the < a href = 'SkCanvas_Reference#Clip' > Canvas Clip< / a > and < a href = 'SkCanvas_Reference#Matrix' > Canvas Matrix< / a > .

Various options apply to text, strokes and fills, and images.
2017-07-28 19:18:29 +00:00
Some options may not be implemented on all platforms; in these cases, setting
2018-05-16 11:07:07 +00:00
the option has no effect. Some options are conveniences that duplicate < a href = 'SkCanvas_Reference#Canvas' > Canvas< / a >
2017-07-28 19:18:29 +00:00
functionality; for instance, text size is identical to matrix scale.
2018-05-16 11:07:07 +00:00
< a href = '#Paint' > Paint< / a > options are rarely exclusive; each option modifies a stage of the drawing
pipeline and multiple pipeline stages may be affected by a single < a href = '#Paint' > Paint< / a > .

< a href = '#Paint' > Paint< / a > collects effects and filters that describe single-pass and multiple-pass
2017-07-28 19:18:29 +00:00
algorithms that alter the drawing geometry, color, and transparency. For instance,
2018-05-16 11:07:07 +00:00
< a href = '#Paint' > Paint< / a > does not directly implement dashing or blur, but contains the objects that do so.
2017-07-28 19:18:29 +00:00
2018-05-16 11:07:07 +00:00
The objects contained by < a href = '#Paint' > Paint< / a > are opaque, and cannot be edited outside of the < a href = '#Paint' > Paint< / a >
2017-07-28 19:18:29 +00:00
to affect it. The implementation is free to defer computations associated with the
2018-05-16 11:07:07 +00:00
< a href = '#Paint' > Paint< / a > , or ignore them altogether. For instance, some GPU implementations draw all

< a href = 'SkPath_Reference#Path' > Path< / a > geometries with < a href = '#Anti_Alias' > Anti Aliasing< / a > , regardless of how < a href = '#SkPaint_kAntiAlias_Flag' > SkPaint::kAntiAlias Flag< / a >

is set in < a href = '#Paint' > Paint< / a > .

2018-05-16 11:07:07 +00:00
< a href = '#Paint' > Paint< / a > describes a single color, a single font, a single image quality, and so on.
2017-07-28 19:18:29 +00:00
Multiple colors are drawn either by using multiple paints or with objects like

Makes a shallow copy of < a href = '#Paint' > Paint< / a > . < a href = 'undocumented#Typeface' > Typeface< / a > , < a href = 'undocumented#Path_Effect' > Path Effect< / a > , < a href = 'undocumented#Shader' > Shader< / a > ,
< a href = 'undocumented#Mask_Filter' > Mask Filter< / a > , < a href = 'undocumented#Color_Filter' > Color Filter< / a > , < a href = 'undocumented#Draw_Looper' > Draw Looper< / a > , and < a href = 'undocumented#Image_Filter' > Image Filter< / a > are shared
between the original < a href = '#SkPaint_copy_const_SkPaint_paint' > paint< / a > and the copy. Objects containing < a href = 'undocumented#Reference_Count' > Reference Count< / a > increment
2017-08-03 21:14:08 +00:00
their references by one.
2017-07-28 19:18:29 +00:00
2018-05-16 11:07:07 +00:00
The referenced objects < a href = 'undocumented#Path_Effect' > Path Effect< / a > , < a href = 'undocumented#Shader' > Shader< / a > , < a href = 'undocumented#Mask_Filter' > Mask Filter< / a > , < a href = 'undocumented#Color_Filter' > Color Filter< / a > ,
< a href = 'undocumented#Draw_Looper' > Draw Looper< / a > , and < a href = 'undocumented#Image_Filter' > Image Filter< / a > cannot be modified after they are created.
This prevents objects with < a href = 'undocumented#Reference_Count' > Reference Count< / a > from being modified once < a href = '#Paint' > Paint< / a > refers to them.

Returns a hash generated from < a href = '#Paint' > Paint< / a > values and pointers.
2017-07-28 19:18:29 +00:00
Identical hashes guarantee that the paints are
equivalent, but differing hashes do not guarantee that the paints have differing
contents.
2018-05-16 11:07:07 +00:00
If < a href = '#SkPaint_equal_operator' > operator==(const SkPaint& a, const SkPaint& b)< / a > returns true for two paints,
2017-07-28 19:18:29 +00:00
their hashes are also equal.
The hash returned is platform and implementation specific.
### Return Value
a shallow hash

< a href = '#SkPaint_Hinting' > Hinting< / a > adjusts the glyph outlines so that the shape provides a uniform
look at a given point size on font engines that support it. < a href = '#SkPaint_Hinting' > Hinting< / a > may have a

muted effect or no effect at all depending on the platform.
2018-01-04 21:11:51 +00:00
The four levels roughly control corresponding features on platforms that use FreeType
2018-05-16 11:07:07 +00:00
as the < a href = 'undocumented#Engine' > Font Engine< / a > .

Leaves glyph outlines unchanged from their native representation.
2018-01-04 21:11:51 +00:00
With FreeType, this is equivalent to the FT_LOAD_NO_HINTING
bit-field constant supplied to FT_Load_Glyph, which indicates that the vector
2017-07-28 19:18:29 +00:00
outline being loaded should not be fitted to the pixel grid but simply scaled
2018-03-05 18:26:16 +00:00
to 26.6 fractional pixels.

Modifies glyph outlines minimally to improve constrast.
2018-01-04 21:11:51 +00:00
With FreeType, this is equivalent in spirit to the
FT_LOAD_TARGET_LIGHT value supplied to FT_Load_Glyph. It chooses a
2017-07-28 19:18:29 +00:00
lighter hinting algorithm for non-monochrome modes.
2018-05-16 11:07:07 +00:00

Modifies glyph outlines to improve constrast. This is the default.
2018-01-04 21:11:51 +00:00
With FreeType, this supplies FT_LOAD_TARGET_NORMAL to FT_Load_Glyph,
choosing the default hinting algorithm, which is optimized for standard
2018-03-05 18:26:16 +00:00
gray-level rendering.

Modifies glyph outlines for maximum constrast. With FreeType, this selects
2018-05-16 11:07:07 +00:00
FT_LOAD_TARGET_LCD or FT_LOAD_TARGET_LCD_V if < a href = '#SkPaint_kLCDRenderText_Flag' > kLCDRenderText Flag< / a > is set.
2018-01-04 21:11:51 +00:00
FT_LOAD_TARGET_LCD is a variant of FT_LOAD_TARGET_NORMAL optimized for
horizontally decimated LCD displays; FT_LOAD_TARGET_LCD_V is a
2018-03-05 18:26:16 +00:00
variant of FT_LOAD_TARGET_NORMAL optimized for vertically decimated LCD displays.

On < a href = 'undocumented#OS_X' > OS X< / a > and iOS, hinting controls whether < a href = 'undocumented#Core_Graphics' > Core Graphics< / a > dilates the font outlines
2018-05-30 13:21:49 +00:00
to account for LCD text. No hinting uses < a href = 'undocumented#Core_Text' > Core Text< / a > < a href = 'undocumented#Grayscale' > Grayscale< / a > output.
2018-05-16 11:07:07 +00:00
Normal hinting uses < a href = 'undocumented#Core_Text' > Core Text< / a > LCD output. If < a href = '#SkPaint_kLCDRenderText_Flag' > kLCDRenderText Flag< / a > is clear,
2018-05-30 13:21:49 +00:00
the LCD output is reduced to a single < a href = 'undocumented#Grayscale' > Grayscale< / a > channel.

< a href = '#Anti_Alias' > Anti Alias< / a > drawing approximates partial pixel coverage with transparency.
2018-05-16 11:07:07 +00:00
If < a href = '#SkPaint_kAntiAlias_Flag' > kAntiAlias Flag< / a > is clear, pixel centers contained by the shape edge are drawn opaque.
If < a href = '#SkPaint_kAntiAlias_Flag' > kAntiAlias Flag< / a > is set, pixels are drawn with < a href = 'SkColor_Reference#Alpha' > Color Alpha< / a > equal to their coverage.
2017-07-28 19:18:29 +00:00
2018-05-16 11:07:07 +00:00
The rule for < a href = 'undocumented#Alias' > Aliased< / a > pixels is inconsistent across platforms. A shape edge
2017-07-28 19:18:29 +00:00

2017-07-28 19:18:29 +00:00
2018-05-17 16:17:28 +00:00
A platform may only support < a href = '#Anti_Alias' > Anti Aliased< / a > drawing. Some GPU-backed platforms use
< a href = 'undocumented#Supersampling' > Supersampling< / a > to < a href = '#Anti_Alias' > Anti Alias< / a > all drawing, and have no mechanism to selectively

2018-05-16 11:07:07 +00:00
< a href = '#Stroke_Width' > Stroke Width< / a > sets the width for stroking. The width is the thickness
2018-01-04 21:11:51 +00:00
of the stroke perpendicular to the path direction when the paint style is
2018-05-16 11:07:07 +00:00
set to < a href = '#SkPaint_kStroke_Style' > kStroke Style< / a > or < a href = '#SkPaint_kStrokeAndFill_Style' > kStrokeAndFill Style< / a > .
2017-07-28 19:18:29 +00:00
When width is greater than zero, the stroke encompasses as many pixels partially
or fully as needed. When the width equals zero, the paint enables hairlines;
2018-01-04 21:11:51 +00:00
the stroke is always one pixel wide.
2017-07-28 19:18:29 +00:00
2018-05-16 11:07:07 +00:00
The stroke dimensions are scaled by the canvas matrix, but < a href = '#Style_Hairline' > Hairline< / a > stroke
2017-07-28 19:18:29 +00:00
remains one pixel wide regardless of scaling.
The default width for the paint is zero.

affects the four corners of a stroked rectangle, and the connected segments in a
stroked path.
Choose miter join to draw sharp corners. Choose round join to draw a circle with a
radius equal to the stroke width on top of the corner. Choose bevel join to minimally
connect the thick strokes.
2018-01-04 21:11:51 +00:00
The fill path constructed to describe the stroked path respects the join setting but may
2017-07-28 19:18:29 +00:00
not contain the actual join. For instance, a fill path constructed with round joins does
not necessarily include circles at each connected segment.

Only call this if < a href = '#SkPaint_canComputeFastBounds' > canComputeFastBounds< / a > returned true. This takes a
2017-07-28 19:18:29 +00:00
raw rectangle (the raw bounds of a shape), and adjusts it for stylistic
2018-05-16 11:07:07 +00:00
effects in the paint (e.g. stroking). If needed, it uses the < a href = '#SkPaint_computeFastBounds_storage' > storage< / a >
2017-09-01 19:51:02 +00:00

2018-05-16 11:07:07 +00:00
for < a href = 'SkCanvas_Reference#SkCanvas_quickReject' > SkCanvas::quickReject< / a > tests.
The returned < a href = 'SkRect_Reference#Rect' > Rect< / a > will either be < a href = '#SkPaint_computeFastBounds_orig' > orig< / a > or < a href = '#SkPaint_computeFastBounds_storage' > storage< / a > , thus the caller
should not rely on < a href = '#SkPaint_computeFastBounds_storage' > storage< / a > being set to the result, but should always
use the returned value. It is legal for < a href = '#SkPaint_computeFastBounds_orig' > orig< / a > and < a href = '#SkPaint_computeFastBounds_storage' > storage< / a > to be the same
