The moveTo function is used whilst drawing paths to the
canvas to move the 'pen' to a new set of coordinates without drawing a
line between them. Like the lineTo function, only a single
pair of X/Y coordinates is given to the function.
With some of the path functions (eg bezierCurveTo,
quadraticCurveTo) the first point is specified by using the
moveTo function.
Arguments to the function
- The
x-axiscoordinate - The
y-axiscoordinate
