begins a path, or resets the current path.
Adds a point to the current path by using the specified control points that represent a cubic Bézier curve.
A cubic bezier curve requires three points. The first two points are control points that are used in the cubic Bézier calculation and the last point is the ending point for the curve. The starting point for the curve is the last point in the current path. If a path does not exist, use the beginPath() and moveTo() methods to define a starting point.
Clears the specified pixels within a given rectangle.
Clears the specified pixels within a given rectangle.
Clips a region of any shape and size from the original canvas.
Once a region is clipped, all future drawing will be limited to the clipped region (no access to other regions on the canvas). You can however save the current canvas region using the save() method before using the clip() method, and restore it (with the restore() method) any time in the future.

Use the stroke() method to actually draw the path on the canvas.
Adds a point to the current path by using the specified control points that represent a quadratic Bézier curve.
A quadratic Bézier curve requires two points. The first point is a control point that is used in the quadratic Bézier calculation and the second point is the ending point for the curve. The starting point for the curve is the last point in the current path. If a path does not exist, use the beginPath() and moveTo() methods to define a starting point.
Creates a rectangle.
Creates a rectangle.
Returns previously saved path state and attributes.
Method rotates the current drawing.
The rotation will only affect drawings made AFTER the rotation is done.
Saves the state of the current context.
Scales the current drawing, bigger or smaller.
Scales the current drawing, bigger or smaller.
Sets the line dash pattern.
Resets the current transform to the identity matrix, and then runs transform() with the same arguments.
The transformation will only affect drawings made after the transform() method is called. The transform() method behaves relatively to other transformations made by rotate(), scale(), translate(), or transform(). Example: If you already have set your drawing to scale by two, and the transform() method scales your drawings by two, your drawings will now scale by four.
Draws the path you have defined.
Draws a rectangle (no fill). The default color of the stroke is black.
Draws a rectangle (no fill). The default color of the stroke is black.
Draws text (with no fill) on the canvas. The default color of the text is black.
Draws text (with no fill) on the canvas. The default color of the text is black.
Replaces the current transformation matrix.
The transformation will only affect drawings made after the transform() method is called. The transform() method behaves relatively to other transformations made by rotate(), scale(), translate(), or transform(). Example: If you already have set your drawing to scale by two, and the transform() method scales your drawings by two, your drawings will now scale by four.
Remaps the (0,0) position on the canvas.
When you call a method such as fillRect() after translate(), the value is added to the x- and y-coordinate values.
Remaps the (0,0) position on the canvas.
When you call a method such as fillRect() after translate(), the value is added to the x- and y-coordinate values.
