SkPaint Reference
===

# <a name="Paint"></a> Paint

# <a name="SkPaint"></a> Class SkPaint
<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="#Clip">Canvas Clip</a> and <a href="#Matrix">Canvas Matrix</a>.

Various options apply to text, strokes and fills, and images.

Some options may not be implemented on all platforms; in these cases, setting
the option has no effect. Some options are conveniences that duplicate <a href="SkCanvas_Reference#Canvas">Canvas</a>
functionality; for instance, text size is identical to matrix scale.

<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
algorithms that alter the drawing geometry, color, and transparency. For instance,
<a href="#Paint">Paint</a> does not directly implement dashing or blur, but contains the objects that do so.

The objects contained by <a href="#Paint">Paint</a> are opaque, and cannot be edited outside of the <a href="#Paint">Paint</a>
to affect it. The implementation is free to defer computations associated with the
<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 Anti-aliasing, regardless of how <a href="#SkPaint_kAntiAlias_Flag">SkPaint::kAntiAlias Flag</a>
is set in <a href="#Paint">Paint</a>.

<a href="#Paint">Paint</a> describes a single color, a single font, a single image quality, and so on.
Multiple colors are drawn either by using multiple paints or with objects like
<a href="undocumented#Shader">Shader</a> attached to <a href="#Paint">Paint</a>.

# <a name="Anti-alias"></a> Anti-alias
Anti-alias drawing approximates partial pixel coverage with transparency.
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="#Alpha">Color Alpha</a> equal to their coverage.

The rule for <a href="#Alias">Aliased</a> pixels is inconsistent across platforms. A shape edge
passing through the pixel center may, but is not required to, draw the pixel.

<a href="undocumented#Raster_Engine">Raster Engine</a> draws <a href="#Alias">Aliased</a> pixels whose centers are on or to the right of the start of an
active <a href="SkPath_Reference#Path">Path</a> edge, and whose center is to the left of the end of the active <a href="SkPath_Reference#Path">Path</a> edge.

A platform may only support Anti-aliased drawing. Some GPU-backed platforms use

# <a name="Dither"></a> Dither
<a href="#Dither">Dither</a> increases fidelity by adjusting the color of adjacent pixels.
This can help to smooth color transitions and reducing banding in gradients.
Dithering lessens visible banding from <a href="undocumented#SkColorType">kRGB 565 SkColorType</a>
and <a href="undocumented#SkColorType">kRGBA 8888 SkColorType</a> gradients,
and improves rendering into a <a href="undocumented#SkColorType">kRGB 565 SkColorType</a> <a href="SkSurface_Reference#Surface">Surface</a>.

Dithering is always enabled for linear gradients drawing into
<a href="undocumented#SkColorType">kRGB 565 SkColorType</a> <a href="SkSurface_Reference#Surface">Surface</a> and <a href="undocumented#SkColorType">kRGBA 8888 SkColorType</a> <a href="SkSurface_Reference#Surface">Surface</a>.
<a href="#Dither">Dither</a> cannot be enabled for <a href="undocumented#SkColorType">kAlpha 8 SkColorType</a> <a href="SkSurface_Reference#Surface">Surface</a> and
<a href="undocumented#SkColorType">kRGBA F16 SkColorType</a> <a href="SkSurface_Reference#Surface">Surface</a>.

<a href="#Dither">Dither</a> is disabled by default.
<a href="#Dither">Dither</a> can be enabled by default by setting <a href="undocumented#SkPaintDefaults_Flags">SkPaintDefaults Flags</a> to <a href="#SkPaint_kDither_Flag">kDither Flag</a>
at compile time.

Some platform implementations may ignore dithering. Setto ignore <a href="#Dither">Dither</a> on <a href="undocumented#GPU_Surface">GPU Surface</a>.

### Example

is positioned to the right of the preceding glyph. <a href="#Vertical_Text">Vertical Text</a> sets successive
<a href="#Glyph">Glyphs</a> to position below the preceding glyph.

Skia can translate text character codes as a series of <a href="#Glyph">Glyphs</a>, but does not implement
font substitution,
textual substitution, line layout, or contextual spacing like Kerning pairs. Use
a text shaping engine like <a href="http://harfbuzz.org/">HarfBuzz</a> to translate text runs
into glyph series.

<a href="#Vertical_Text">Vertical Text</a> is clear if text is drawn left to right or set if drawn from top to bottom.

<a href="#SkPaint_Flags">Flags</a> <a href="#SkPaint_kVerticalText_Flag">kVerticalText Flag</a> if clear draws text left to right.
<a href="#SkPaint_Flags">Flags</a> <a href="#SkPaint_kVerticalText_Flag">kVerticalText Flag</a> if set draws text top to bottom.

<a href="#Vertical_Text">Vertical Text</a> is clear by default.
<a href="#Vertical_Text">Vertical Text</a> can be set by default by setting <a href="undocumented#SkPaintDefaults_Flags">SkPaintDefaults Flags</a> to
<a href="#SkPaint_kVerticalText_Flag">kVerticalText Flag</a> at compile time.

# <a name="Fake_Bold"></a> Fake Bold
<a href="#Fake_Bold">Fake Bold</a> approximates the bold font style accompanying a normal font when a bold font face
is not available. Skia does not provide font substitution; it is up to the client to find the
bold font face using the platform <a href="undocumented#Font_Manager">Font Manager</a>.

Use <a href="#Text_Skew_X">Text Skew X</a> to approximate an italic font style when the italic font face
is not available.

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

<a href="#Fake_Bold">Fake Bold</a> is disabled by default.

# <a name="Style"></a> Style
<a href="#Style">Style</a> specifies if the geometry is filled, stroked, or both filled and stroked.
Some shapes ignore <a href="#Style">Style</a> and are always drawn filled or stroked.

Set <a href="#Style">Style</a> to <a href="#SkPaint_kFill_Style">kFill Style</a> to fill the shape.
The fill covers the area inside the geometry for most shapes.

Set <a href="#Style">Style</a> to <a href="#SkPaint_kStroke_Style">kStroke Style</a> to stroke the shape.

## <a name="Fill"></a> Fill

### See Also

<a href="#Fill_Type">Path Fill Type</a>

## <a name="Stroke"></a> Stroke

The stroke covers the area described by following the shape edge with a pen or brush of
<a href="#Stroke_Width">Stroke Width</a>. The area covered where the shape starts and stops is described by <a href="#Stroke_Cap">Stroke Cap</a>.
The area covered where the shape turns a corner is described by <a href="#Stroke_Join">Stroke Join</a>.
The stroke is centered on the shape; it extends equally on either side of the shape edge.

As <a href="#Stroke_Width">Stroke Width</a> gets smaller, the drawn path frame is thinner. <a href="#Stroke_Width">Stroke Width</a> less than one
may have gaps, and if <a href="#SkPaint_kAntiAlias_Flag">kAntiAlias Flag</a> is set, <a href="#Alpha">Color Alpha</a> will increase to visually decrease coverage.

## <a name="Hairline"></a> Hairline

<a href="#Stroke_Width">Stroke Width</a> of zero has a special meaning and switches drawing to use <a href="#Hairline">Hairline</a>.
<a href="#Hairline">Hairline</a> draws the thinnest continuous frame. If <a href="#SkPaint_kAntiAlias_Flag">kAntiAlias Flag</a> is clear, adjacent pixels
flow horizontally, vertically,or diagonally.

<a href="SkPath_Reference#Path">Path</a> drawing with <a href="#Hairline">Hairline</a> may hit the same pixel more than once. For instance, <a href="SkPath_Reference#Path">Path</a> containing
two lines in one <a href="#Contour">Path Contour</a> will draw the corner point once, but may both lines may draw the adjacent
pixel. If <a href="#SkPaint_kAntiAlias_Flag">kAntiAlias Flag</a> is set, transparency is applied twice, resulting in a darker pixel. Some
GPU-backed implementations apply transparency at a later drawing stage, avoiding double hit pixels
while stroking.

## <a name="SkPaint_Style"></a> Enum SkPaint::Style

<pre style="padding: 1em 1em 1em 1em;width: 62.5em; background-color: #f0f0f0">
enum <a href="#SkPaint_Style">Style</a> {

<a href="#SkPaint_kStrokeAndFill_Style">kStrokeAndFill Style</a>,
};</pre>

Set <a href="#SkPaint_Style">Style</a> to fill, stroke, or both fill and stroke geometry.
The stroke and fill
share all paint attributes; for instance, they are drawn with the same color.

Use <a href="#SkPaint_kStrokeAndFill_Style">kStrokeAndFill Style</a> to avoid hitting the same pixels twice with a stroke draw and
a fill draw.

# <a name="Stroke_Width"></a> Stroke Width
<a href="#Stroke_Width">Stroke Width</a> sets the width for stroking. The width is the thickness
of the stroke perpendicular to the path direction when the paint style is
set to <a href="#SkPaint_kStroke_Style">kStroke Style</a> or <a href="#SkPaint_kStrokeAndFill_Style">kStrokeAndFill Style</a>.

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;
the stroke is always one pixel wide.

The stroke dimensions are scaled by the canvas matrix, but <a href="#Hairline">Hairline</a> stroke
remains one pixel wide regardless of scaling.

The default width for the paint is zero.

# <a name="Miter_Limit"></a> Miter Limit
<a href="#Miter_Limit">Miter Limit</a> specifies the maximum miter length,
relative to the stroke width.

<a href="#Miter_Limit">Miter Limit</a> is used when the <a href="#Stroke_Join">Stroke Join</a>

or <a href="#SkPaint_kStrokeAndFill_Style">kStrokeAndFill Style</a>.

If the miter at a corner exceeds this limit, <a href="#SkPaint_kMiter_Join">kMiter Join</a>
is replaced with <a href="#SkPaint_kBevel_Join">kBevel Join</a>.

<a href="#Miter_Limit">Miter Limit</a> can be computed from the corner angle:

miter limit = 1 / sin ( angle / 2 )<a href="#Miter_Limit">Miter Limit</a> default value is 4.
The default may be changed at compile time by setting <a href="undocumented#SkPaintDefaults_MiterLimit">SkPaintDefaults MiterLimit</a>
in "SkUserConfig.h" or as a define supplied by the build environment.

Here are some miter limits and the angles that triggers them.

| miter limit | angle in degrees |
| --- | ---  |
| 10 | 11.48 |
| 9 | 12.76 |
| 8 | 14.36 |

<a href="#SkPaint_Join">Join</a> specifies how corners are drawn when a shape is stroked. <a href="#SkPaint_Join">Join</a>
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.

The fill path constructed to describe the stroked path respects the join setting but may
not contain the actual join. For instance, a fill path constructed with round joins does
not necessarily include circles at each connected segment.

with <a href="undocumented#Blend_Mode">Blend Mode</a> set to <a href="#SkBlendMode_kSrcOver">SkBlendMode::kSrcOver</a>. <a href="undocumented#Image_Filter">Image Filter</a> creates a new bitmap,
which is drawn to the device using the set <a href="undocumented#Blend_Mode">Blend Mode</a>.

<a href="undocumented#Image_Filter">Image Filter</a> is higher level than <a href="undocumented#Mask_Filter">Mask Filter</a>; for instance, an <a href="undocumented#Image_Filter">Image Filter</a>

The return count is zero or a multiple of two, and is at most twice the number of <a href="#Glyph">Glyphs</a> in
the string.
Uses <a href="undocumented#Typeface">Typeface</a> to get the glyph paths,
and <a href="#Text_Size">Text Size</a>, <a href="#Fake_Bold">Fake Bold</a>, and <a href="undocumented#Path_Effect">Path Effect</a> to scale and modify the glyph paths.
Uses run array and <a href="#Text_Align">Text Align</a> to position <a href="#SkPaint_getTextBlobIntercepts_intervals">intervals</a>.
<a href="#Text_Encoding">Text Encoding</a> must be set to <a href="#SkPaint_kGlyphID_TextEncoding">SkPaint::kGlyphID TextEncoding</a>.

Pass nullptr for <a href="#SkPaint_getTextBlobIntercepts_intervals">intervals</a> to determine the size of the interval array.
<a href="#SkPaint_getTextBlobIntercepts_intervals">intervals</a> are cached to improve performance for multiple calls.

### Parameters

<table>  <tr>    <td><a name="SkPaint_getTextBlobIntercepts_blob"> <code><strong>blob </strong></code> </a></td> <td>
<a href="#Glyph">Glyphs</a>, positions, and text paint attributes</td>
  </tr>  <tr>    <td><a name="SkPaint_getTextBlobIntercepts_bounds"> <code><strong>bounds </strong></code> </a></td> <td>
lower and upper line parallel to the advance</td>
  </tr>  <tr>    <td><a name="SkPaint_getTextBlobIntercepts_intervals"> <code><strong>intervals </strong></code> </a></td> <td>
returned intersections; may be nullptr</td>
  </tr>
</table>

### Return Value

number of intersections; may be zero

<a name="SkPaint_nothingToDraw"></a>
## nothingToDraw

<pre style="padding: 1em 1em 1em 1em;width: 62.5em; background-color: #f0f0f0">
bool nothingToDraw() const
</pre>

Returns true if <a href="#Paint">Paint</a> prevents all drawing;
otherwise, the <a href="#Paint">Paint</a> may or may not allow drawing.

Returns true if, for example, <a href="undocumented#Blend_Mode">Blend Mode</a> combined with <a href="#Alpha">Color Alpha</a> computes a
new <a href="#Alpha">Alpha</a> of zero.

### Return Value

true if <a href="#Paint">Paint</a> prevents all drawing

### Example

<div><fiddle-embed name="fc5a771b915ac341f56554f01d282831">

#### Example Output

~~~~
initial nothing to draw: false
blend dst nothing to draw: true
blend src over nothing to draw: false

# <a name="Fast_Bounds"></a> Fast Bounds
<a href="#Fast_Bounds">Fast Bounds</a> methods conservatively outset a drawing bounds by additional area
<a href="#Paint">Paint</a> may draw to.

<a name="SkPaint_canComputeFastBounds"></a>
## canComputeFastBounds

<pre style="padding: 1em 1em 1em 1em;width: 62.5em; background-color: #f0f0f0">
bool canComputeFastBounds() const
</pre>

Returns true if <a href="#Paint">Paint</a> does not include elements requiring extensive computation
to compute <a href="undocumented#Device">Device</a> bounds of drawn geometry. For instance, <a href="#Paint">Paint</a> with <a href="undocumented#Path_Effect">Path Effect</a>
always returns false.

### Return Value

true if <a href="#Paint">Paint</a> allows for fast computation of bounds

---

<a name="SkPaint_computeFastBounds"></a>
## computeFastBounds

<pre style="padding: 1em 1em 1em 1em;width: 62.5em; background-color: #f0f0f0">
const SkRect& computeFastBounds(const SkRect& orig, SkRect* storage) const
</pre>

Only call this if <a href="#SkPaint_canComputeFastBounds">canComputeFastBounds</a> returned true. This takes a
raw rectangle (the raw bounds of a shape), and adjusts it for stylistic
effects in the paint (e.g. stroking). If needed, it uses the <a href="#SkPaint_computeFastBounds_storage">storage</a>
parameter. It returns the adjusted bounds that can then be used
for <a href="#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
<a href="SkRect_Reference#Rect">Rect</a>.

### Parameters

<table>  <tr>    <td><a name="SkPaint_computeFastBounds_orig"> <code><strong>orig </strong></code> </a></td> <td>
geometry modified by <a href="#Paint">Paint</a> when drawn</td>
  </tr>  <tr>    <td><a name="SkPaint_computeFastBounds_storage"> <code><strong>storage </strong></code> </a></td> <td>
computed bounds of geometry; may not be nullptr</td>
  </tr>
</table>

### Return Value

fast computed bounds

<a name="SkPaint_computeFastStrokeBounds"></a>
## computeFastStrokeBounds

<pre style="padding: 1em 1em 1em 1em;width: 62.5em; background-color: #f0f0f0">
const SkRect& computeFastStrokeBounds(const SkRect& orig, SkRect* storage) const
</pre>

### Parameters

<table>  <tr>    <td><a name="SkPaint_computeFastStrokeBounds_orig"> <code><strong>orig </strong></code> </a></td> <td>
geometry modified by <a href="#Paint">Paint</a> when drawn</td>
  </tr>  <tr>    <td><a name="SkPaint_computeFastStrokeBounds_storage"> <code><strong>storage </strong></code> </a></td> <td>

<a name="SkPaint_doComputeFastBounds"></a>
## doComputeFastBounds

<pre style="padding: 1em 1em 1em 1em;width: 62.5em; background-color: #f0f0f0">
const SkRect& doComputeFastBounds(const SkRect& orig, SkRect* storage, Style style) const
</pre>

Computes the bounds, overriding the <a href="#Paint">Paint</a> <a href="#SkPaint_Style">Style</a>. This can be used to
account for additional width required by stroking <a href="#SkPaint_doComputeFastBounds_orig">orig</a>, without
altering <a href="#SkPaint_Style">Style</a> set to fill.

### Parameters

<table>  <tr>    <td><a name="SkPaint_doComputeFastBounds_orig"> <code><strong>orig </strong></code> </a></td> <td>
geometry modified by <a href="#Paint">Paint</a> when drawn</td>
  </tr>  <tr>    <td><a name="SkPaint_doComputeFastBounds_storage"> <code><strong>storage </strong></code> </a></td> <td>
computed bounds of geometry</td>
  </tr>  <tr>    <td><a name="SkPaint_doComputeFastBounds_style"> <code><strong>style </strong></code> </a></td> <td>
overrides <a href="#SkPaint_Style">Style</a></td>
  </tr>

## toString

<pre style="padding: 1em 1em 1em 1em;width: 62.5em; background-color: #f0f0f0">
void toString(SkString* str) const;
</pre>

Creates string representation of <a href="#Paint">Paint</a>. The representation is read by
internal debugging tools. The interface and implementation may be
suppressed by defining SK_IGNORE_TO_STRING.

### Parameters

<table>  <tr>    <td><a name="SkPaint_toString_str"> <code><strong>str </strong></code> </a></td> <td>
storage for string representation of <a href="#Paint">Paint</a></td>
  </tr>
</table>

### Example
