Graphics component reference

The Graphics component provides a series of drawing interfaces that reference the canvas's drawing interface.


Function Function Explanation
moveTo (x, y) Move path start point to (x,y)
lineTo (x, y) Adds a straight line to the path
bezierCurveTo (c1x, c1y, c2x, c2y, x, y) Adds a cubic Bézier curve to the path
quadraticCurveTo (cx, cy, x, y) Adds a quadratic Bézier curve to the path
arc (cx, cy, r, a0, a1, counterclockwise) Adds an arc to the path which is centered at (cx, cy) position with radius r starting at startAngle and ending at endAngle going in the given direction by counterclockwise (defaulting to false).
ellipse (cx, cy, rx, ry) Adds an ellipse to the path
circle (cx, cy, r) Adds an circle to the path
rect (x, y, w, h) Adds an rectangle to the path
close () Adds an round corner rectangle to the path
stroke () Draws a filled rectangle
fill () Erasing any previously drawn content
clear () Causes the point of the pen to move back to the start of the current path. It tries to add a straight line from the current point to the start
