Can I paint with smoothing on canvas?

Question

Can I paint using anti-aliasing on canvas?

I need my circles, and the line has smooth edges.

Answer 1

Paint operations want Paint . In this Paint you set Paint.setFlags(Paint.ANTI_ALIAS_FLAG)

Answer 2

Check this. It fairly uses smooth edges. http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/graphics/FingerPaint.html

Properties of the paint necessary to obtain smoothing:

  mPaint = new Paint(); mPaint.setAntiAlias(true); 

To use the picture:

  mPath = new Path(); mPath.reset(); mPath.moveTo(x, y);//can be used where to trigger the path 

The onDraw method must contain:

  canvas.drawPath(mPath, mPaint); 

Declare mPath and mPaint global.
