Method Detail

startHole

public void startHole(float sx,
                      float sy)

Start building a hole in the previously defined contour

Parameters:

sx - The start point of the hole

sy - The start point of the hole

lineTo

public void lineTo(float x,
                   float y)

Add a line to the contour or hole which ends at the specified location.

Parameters:

x - The x coordinate to draw the line to

y - The y coordiante to draw the line to

close

public void close()

Close the path to form a polygon

curveTo
