<a href='SkCanvas_Reference#Canvas'>Canvas</a> provides an interface for drawing, and how the drawing is clipped and transformed.
<a href='SkCanvas_Reference#Canvas'>Canvas</a> contains a stack of <a href='SkMatrix_Reference#Matrix'>Matrix</a> and Clip values.
<a href='SkCanvas_Reference#Canvas'>Canvas</a> and <a href='SkPaint_Reference#Paint'>Paint</a> together provide the state to draw into <a href='SkSurface_Reference#Surface'>Surface</a> or <a href='undocumented#Device'>Device</a>.
Each <a href='SkCanvas_Reference#Canvas'>Canvas</a> draw call transforms the geometry of the object by the concatenation of all
<a href='SkMatrix_Reference#Matrix'>Matrix</a> values in the stack. The transformed geometry is clipped by the intersection
of all of Clip values in the stack. The <a href='SkCanvas_Reference#Canvas'>Canvas</a> draw calls use <a href='SkPaint_Reference#Paint'>Paint</a> to supply drawing
state such as <a href='SkColor_Reference#Color'>Color</a>, <a href='undocumented#Typeface'>Typeface</a>, <a href='undocumented#Text'>text</a> <a href='undocumented#Size'>size</a>, stroke width, <a href='undocumented#Shader'>Shader</a> and so on.
To draw to a pixel-based destination, create <a href='#Raster_Surface'>Raster_Surface</a> or <a href='#GPU_Surface'>GPU_Surface</a>.
Request <a href='SkCanvas_Reference#Canvas'>Canvas</a> from <a href='SkSurface_Reference#Surface'>Surface</a> to obtain the interface to draw.
<a href='SkCanvas_Reference#Canvas'>Canvas</a> generated by <a href='#Raster_Surface'>Raster_Surface</a> draws to memory visible to the CPU.
<a href='SkCanvas_Reference#Canvas'>Canvas</a> generated by <a href='#GPU_Surface'>GPU_Surface</a> uses Vulkan or OpenGL to draw to the GPU.
To draw to a <a href='undocumented#Document'>document</a>, obtain <a href='SkCanvas_Reference#Canvas'>Canvas</a> from <a href='#SVG_Canvas'>SVG_Canvas</a>, <a href='#Document_PDF'>Document_PDF</a>, or <a href='#Picture_Recorder'>Picture_Recorder</a>.
<a href='undocumented#Document'>Document</a> based <a href='SkCanvas_Reference#Canvas'>Canvas</a> and other <a href='SkCanvas_Reference#Canvas'>Canvas</a> subclasses reference <a href='undocumented#Device'>Device</a> describing the
destination.
<a href='SkCanvas_Reference#Canvas'>Canvas</a> can be constructed to draw to <a href='SkBitmap_Reference#Bitmap'>Bitmap</a> without first creating <a href='#Raster_Surface'>Raster_Surface</a>.
This approach may be deprecated in the future.
<a href='SkCanvas_Reference#Canvas'>Canvas</a> may be created directly when no <a href='SkSurface_Reference#Surface'>Surface</a> is required; some <a href='SkCanvas_Reference#Canvas'>Canvas</a> methods
implicitly create <a href='#Raster_Surface'>Raster_Surface</a>.

<a href='SkCanvas_Reference#SkCanvas'>SkCanvas</a>(int width, int height, const <a href='undocumented#SkSurfaceProps'>SkSurfaceProps</a>* props = nullptr)
</pre>
Creates <a href='SkCanvas_Reference#SkCanvas'>SkCanvas</a> of the specified dimensions without a <a href='SkSurface_Reference#SkSurface'>SkSurface</a>.
Used by subclasses with custom implementations for draw member functions.
If <a href='#SkCanvas_int_int_const_SkSurfaceProps_star_props'>props</a> equals nullptr, <a href='undocumented#SkSurfaceProps'>SkSurfaceProps</a> are created with
<a href='undocumented#SkSurfaceProps'>SkSurfaceProps</a>::<a href='#SkSurfaceProps_InitType'>InitType</a> settings, which choose the <a href='undocumented#Pixel'>pixel</a> striping
direction and order. Since a platform may dynamically change its direction when
the <a href='undocumented#Device'>device</a> is rotated, and since a platform may have multiple monitors with
different characteristics, it is best not to rely on this legacy behavior.
### Parameters
<table> <tr> <td><a name='SkCanvas_int_int_const_SkSurfaceProps_star_width'><code><strong>width</strong></code></a></td>
<td>zero or greater</td>

<a name='State_Stack'></a>
---
<a href='SkCanvas_Reference#Canvas'>Canvas</a> maintains a stack of state that allows hierarchical drawing, commonly used
to implement windows and views. The initial state has an identity <a href='SkMatrix_Reference#Matrix'>matrix</a> and and
an infinite clip. Even with a wide-open clip, drawing is constrained by the
bounds of the <a href='SkCanvas_Reference#Canvas'>Canvas</a> <a href='SkSurface_Reference#Surface'>Surface</a> or <a href='undocumented#Device'>Device</a>.
<a href='SkCanvas_Reference#Canvas'>Canvas</a> savable state consists of Clip and <a href='SkMatrix_Reference#Matrix'>Matrix</a>.
Clip describes the area that may be drawn to.
<a href='SkMatrix_Reference#Matrix'>Matrix</a> transforms the geometry.
<a href='#SkCanvas_save'>save()</a>, <a href='#SkCanvas_saveLayer'>saveLayer</a>, <a href='#SkCanvas_saveLayerPreserveLCDTextRequests'>saveLayerPreserveLCDTextRequests</a>, and <a href='#SkCanvas_saveLayerAlpha'>saveLayerAlpha</a>
save state and return the depth of the stack.
<a href='#SkCanvas_restore'>restore()</a>, <a href='#SkCanvas_restoreToCount'>restoreToCount</a>, and ~<a href='#SkCanvas_empty_constructor'>SkCanvas()</a> revert state to its value when saved.
Each state on the stack intersects Clip with the previous Clip,
and concatenates <a href='SkMatrix_Reference#Matrix'>Matrix</a> with the previous <a href='SkMatrix_Reference#Matrix'>Matrix</a>.
The intersected Clip makes the drawing area the same or smaller;
the concatenated <a href='SkMatrix_Reference#Matrix'>Matrix</a> may move the origin and potentially scale or rotate
the coordinate space.
<a href='SkCanvas_Reference#Canvas'>Canvas</a> does not require balancing the <a href='#State_Stack'>state stack</a> but it is a good idea
to do so. Calling <a href='#SkCanvas_save'>save()</a> without <a href='#SkCanvas_restore'>restore()</a> will eventually cause Skia to fail;
mismatched <a href='#SkCanvas_save'>save()</a> and <a href='#SkCanvas_restore'>restore()</a> create hard to find bugs.
It is not possible to use state to draw outside of the clip defined by the
previous state.
### Example
<div><fiddle-embed name="bb1dbfdca3aedf716beb6f07e2aab065"><div>Draw to ever smaller clips; then restore drawing to full <a href='SkCanvas_Reference#Canvas'>canvas</a>.
Note that the second <a href='#SkCanvas_clipRect'>clipRect</a> is not permitted to enlarge Clip.
</div></fiddle-embed></div>
Each Clip uses the current <a href='SkMatrix_Reference#Matrix'>Matrix</a> for its coordinates.
### Example
<div><fiddle-embed name="9f563a2d60aa31d4b26742e5aa17aa4e"><div>While <a href='#SkCanvas_clipRect'>clipRect</a> is given the same rectangle twice, <a href='SkMatrix_Reference#Matrix'>Matrix</a> makes the second
<a href='#SkCanvas_clipRect'>clipRect</a> draw at half the <a href='undocumented#Size'>size</a> of the first.

int <a href='#SkCanvas_save'>save()</a>

Saves <a href='SkMatrix_Reference#SkMatrix'>SkMatrix</a> and clip.
Calling <a href='#SkCanvas_restore'>restore()</a> discards changes to <a href='SkMatrix_Reference#SkMatrix'>SkMatrix</a> and clip,
restoring the <a href='SkMatrix_Reference#SkMatrix'>SkMatrix</a> and clip to their state when <a href='#SkCanvas_save'>save()</a> was called.

Saves <a href='SkMatrix_Reference#SkMatrix'>SkMatrix</a> and clip, and allocates <a href='SkBitmap_Reference#SkBitmap'>SkBitmap</a> for subsequent drawing.
Calling <a href='#SkCanvas_restore'>restore()</a> discards changes to <a href='SkMatrix_Reference#SkMatrix'>SkMatrix</a> and clip,
and blends <a href='SkCanvas_Reference#Layer'>layer</a> with <a href='#SkCanvas_saveLayerAlpha_alpha'>alpha</a> opacity onto prior <a href='SkCanvas_Reference#Layer'>layer</a>.
<a href='SkMatrix_Reference#SkMatrix'>SkMatrix</a> may be changed by <a href='#SkCanvas_translate'>translate()</a>, <a href='#SkCanvas_scale'>scale()</a>, <a href='#SkCanvas_rotate'>rotate()</a>, <a href='#SkCanvas_skew'>skew()</a>, <a href='#SkCanvas_concat'>concat()</a>,

a specific rectangle, use <a href='#SkCanvas_clipRect'>clipRect</a>().
<a href='#SkCanvas_saveLayerAlpha_alpha'>alpha</a> of zero is fully transparent, 255 is fully opaque.
Call <a href='#SkCanvas_restoreToCount'>restoreToCount</a>() with returned value to restore this and subsequent saves.

<a name='Clip'></a>
---
Clip is built from a stack of clipping <a href='SkPath_Reference#Path'>paths</a>. Each <a href='SkPath_Reference#Path'>Path</a> in the
stack can be constructed from one or more <a href='#Path_Overview_Contour'>Path_Contour</a> elements. The
<a href='#Path_Overview_Contour'>Path_Contour</a> may be composed of any number of <a href='#Path_Verb'>Path_Verb</a> segments. Each
<a href='#Path_Overview_Contour'>Path_Contour</a> forms a closed area; <a href='#Path_Fill_Type'>Path_Fill_Type</a> defines the area enclosed
by <a href='#Path_Overview_Contour'>Path_Contour</a>.
Clip stack of <a href='SkPath_Reference#Path'>Path</a> elements successfully restrict the <a href='SkPath_Reference#Path'>Path</a> area. Each
<a href='SkPath_Reference#Path'>Path</a> is transformed by <a href='SkMatrix_Reference#Matrix'>Matrix</a>, then intersected with or subtracted from the
prior Clip to form the replacement Clip. Use <a href='undocumented#SkClipOp'>SkClipOp</a>::<a href='#SkClipOp_kDifference'>kDifference</a>
to subtract <a href='SkPath_Reference#Path'>Path</a> from Clip; use <a href='undocumented#SkClipOp'>SkClipOp</a>::<a href='#SkClipOp_kIntersect'>kIntersect</a> to intersect <a href='SkPath_Reference#Path'>Path</a>
with Clip.
A clipping <a href='SkPath_Reference#Path'>Path</a> may be <a href='#Paint_Anti_Alias'>Anti_Aliased</a>; if <a href='SkPath_Reference#Path'>Path</a>, after transformation, is
composed of horizontal and vertical <a href='undocumented#Line'>lines</a>, clearing <a href='#Paint_Anti_Alias'>Anti_Alias</a> allows whole pixels
to either be inside or outside the clip. The fastest drawing has a <a href='undocumented#Alias'>Aliased</a>,
rectangular clip.
If clipping <a href='SkPath_Reference#Path'>Path</a> has <a href='#Paint_Anti_Alias'>Anti_Alias</a> set, clip may partially clip a <a href='undocumented#Pixel'>pixel</a>, requiring
that drawing blend partially with the destination along the edge. A rotated
rectangular <a href='#Paint_Anti_Alias'>Anti_Aliased</a> clip looks smoother but draws slower.
Clip can combine with <a href='SkRect_Reference#Rect'>Rect</a> and <a href='#RRect'>Round_Rect</a> primitives; like
<a href='SkPath_Reference#Path'>Path</a>, these are transformed by <a href='SkMatrix_Reference#Matrix'>Matrix</a> before they are combined with Clip.
Clip can combine with <a href='SkRegion_Reference#Region'>Region</a>. <a href='SkRegion_Reference#Region'>Region</a> is assumed to be in <a href='undocumented#Device'>Device</a> coordinates
and is unaffected by <a href='SkMatrix_Reference#Matrix'>Matrix</a>.
### Example

The edge of the <a href='undocumented#Alias'>Aliased</a> clip fully draws pixels in the red <a href='undocumented#Circle'>circle</a>.
