<ahref="SkCanvas_Reference#Canvas">Canvas</a> provides an interface for drawing, and how the drawing is clipped and transformed.
<ahref="SkCanvas_Reference#Canvas">Canvas</a> contains a stack of <ahref="SkCanvas_Reference#Matrix">Matrix</a> and <ahref="SkCanvas_Reference#Clip">Clip</a> values.
<ahref="SkCanvas_Reference#Canvas">Canvas</a> and <ahref="SkPaint_Reference#Paint">Paint</a> together provide the state to draw into <ahref="undocumented#Surface">Surface</a> or <ahref="undocumented#Device">Device</a>.
Each <ahref="SkCanvas_Reference#Canvas">Canvas</a> draw call transforms the geometry of the object by the concatenation of all
<ahref="SkCanvas_Reference#Matrix">Matrix</a> values in the stack. The transformed geometry is clipped by the intersection
of all of <ahref="SkCanvas_Reference#Clip">Clip</a> values in the stack. The <ahref="SkCanvas_Reference#Canvas">Canvas</a> draw calls use <ahref="SkPaint_Reference#Paint">Paint</a> to supply drawing
state such as <ahref="undocumented#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="SkCanvas_Reference#Canvas">Canvas</a> from <ahref="undocumented#Surface">Surface</a> to obtain the interface to draw.

To draw to a document, obtain <ahref="SkCanvas_Reference#Canvas">Canvas</a> from <ahref="undocumented#Canvas">SVG Canvas</a>, <ahref="undocumented#PDF">Document PDF</a>, or <ahref="undocumented#Recorder">Picture Recorder</a>.
