Can I draw with antialiasing on canvas?
Drawing operations want Paint. In this Paint you set Paint.setFlags(Paint.ANTI_ALIAS_FLAG)
Check this out. It fairly uses smooth edges..http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/graphics/FingerPaint.html
The paint properties needed to get anti-aliasing is :
mPaint = new Paint(); mPaint.setAntiAlias(true);For drawing use:
mPath = new Path(); mPath.reset(); mPath.moveTo(x, y);//can be used where to trigger the pathonDraw method should contain:
canvas.drawPath(mPath, mPaint);Declare the mPath and mPaint as global.
You can provide ANTI_ALIAS_FLAG in Paint constructor Paint(int). The ANTI_ALIAS_FLAG flag enables antialiasing when drawing. Enabling this flag will cause all draw operations that support antialiasing to use it.
Or you can set this flag later using setFlags(int) method
Example implementation In Kotlin:
//Paintprivate var indicatorPaint: Paint = Paint(Paint.ANTI_ALIAS_FLAG).apply { isAntiAlias = true color = fillColor strokeWidth = lineThickness.toFloat() style = Paint.Style.STROKE}
