Shifting a graphics Path object over
In Java, Android specifically, how do I transform a Path object over 100 pixels? Like in C#, I would use the following code to do this:
// Create a path and add and ellipse.
GraphicsPath myPath = new GraphicsPath();
myPath.AddEllipse(0, 0, 100, 200);
// Draw the starting position to screen.
e.Graphics.DrawPath(Pens.Black, myPath);
// Move the ellipse 100 points to the right.
Matrix translateMatrix = new Matrix();
translateMatrix.Translate(100, 0);
myPath.Transform(translateMatrix);
// Draw the transformed ellipse to the screen.
e.Graphics.DrawPath(new Pen(Color.Red, 2), myPath);
How do I do this in Android? I already have my Path object:
@Override
protected void onDraw(Canvas canvas) {
super.onDraw(canvas);
Paint pnt = new Paint();
Path p = new Path();
pnt.setStyle(Paint.Style.STROKE);
pnt.setColor(Color.WHITE);
p.moveTo(97.4f, 87.6f);
p.lineTo(97.4f, 3.8f);
p.lineTo(-1.2f, 1.2f);
p.lineTo(-0.4f,-0.4f);
p.lineTo(-0.4f,87f);
p.lineTo(97.4f, 87.6f);
p.close();
canvas.drawPath(p, pnt);
}
What do you I need to do in order to shi开发者_JAVA技巧ft my Path object over 100 pixels?
It's almost the same:
Matrix translateMatrix = new Matrix();
translateMatrix.setTranslate(100,0);
p.transform(translateMatrix);
I didn't test it, just looked into API.
I think Path.offset(float dx, float dy)
is what you're looking for.
