<ahref='#Canvas'>Canvas</a> provides an interface for drawing, and how the drawing is clipped and transformed.
<ahref='#Canvas'>Canvas</a> contains a stack of <ahref='#Matrix'>Matrix</a> and <ahref='#Clip'>Clip</a> values.
<ahref='#Canvas'>Canvas</a> and <ahref='SkPaint_Reference#Paint'>Paint</a> together provide the state to draw into <ahref='SkSurface_Reference#Surface'>Surface</a> or <ahref='undocumented#Device'>Device</a>.
Each <ahref='#Canvas'>Canvas</a> draw call transforms the geometry of the object by the concatenation of all
<ahref='#Matrix'>Matrix</a> values in the stack. The transformed geometry is clipped by the intersection
of all of <ahref='#Clip'>Clip</a> values in the stack. The <ahref='#Canvas'>Canvas</a> draw calls use <ahref='SkPaint_Reference#Paint'>Paint</a> to supply drawing
state such as <ahref='SkColor_Reference#Color'>Color</a>, <ahref='undocumented#Typeface'>Typeface</a>, text size, stroke width, <ahref='undocumented#Shader'>Shader</a> and so on.
To draw to a pixel-based destination, create <ahref='undocumented#Raster_Surface'>Raster Surface</a> or <ahref='undocumented#GPU_Surface'>GPU Surface</a>.
Request <ahref='#Canvas'>Canvas</a> from <ahref='SkSurface_Reference#Surface'>Surface</a> to obtain the interface to draw.
<ahref='#Canvas'>Canvas</a> generated by <ahref='undocumented#Raster_Surface'>Raster Surface</a> draws to memory visible to the CPU.
<ahref='#Canvas'>Canvas</a> generated by <ahref='undocumented#GPU_Surface'>GPU Surface</a> uses Vulkan or OpenGL to draw to the GPU.
To draw to a document, obtain <ahref='#Canvas'>Canvas</a> from <ahref='undocumented#Canvas'>SVG Canvas</a>, <ahref='undocumented#PDF'>Document PDF</a>, or <ahref='undocumented#Recorder'>Picture Recorder</a>.
<ahref='undocumented#Document'>Document</a> based <ahref='#Canvas'>Canvas</a> and other <ahref='#Canvas'>Canvas</a> Subclasses reference <ahref='undocumented#Device'>Device</a> describing the
<ahref='#Canvas'>Canvas</a> can be constructed to draw to <ahref='SkBitmap_Reference#Bitmap'>Bitmap</a> without first creating <ahref='undocumented#Raster_Surface'>Raster Surface</a>.
SkCanvas related constants are defined by <code>enum</code>, <code>enum class</code>, <code>#define</code>, <code>const</code>, and <code>constexpr</code>.
Create the desired type of <ahref='SkSurface_Reference#Surface'>Surface</a> to obtain its <ahref='#Canvas'>Canvas</a> when possible. Useful
when no <ahref='SkSurface_Reference#Surface'>Surface</a> is required, and some helpers implicitly create <ahref='undocumented#Raster_Surface'>Raster Surface</a>.
SkCanvas can be constructed or initialized by these functions, including C++ class constructors.
