Method Detail

draw

public abstract void draw(Canvas canvas)

1. scaleX(float) and scaleY(float) adjust the size of the supplied value from the preview scale to the view scale.
2. translateX(float) and translateY(float) adjust the coordinate from the preview's coordinate system to the view coordinate system.

Parameters:

canvas - drawing canvas
