Android drawCircle's are not always 360 degrees

Question

When I call drawCircle (ex. canvas.drawCircle(x, y, r, mPaint);) and I use Paint Style STROKE to initialize param #4 mPaint, the result doesn't quite make a full 360 degree (2*PI radian) circle in all cases. Sometimes you get a full circle (as I would expect) and sometimes only an arc.

Does someone have an idea what would cause this to happen?

I don't know what cases work and which don't (yet). I've noticed the ones that don't work seem to be the larger circles I'm drawing (>100.0 radius). Could be size related. I am using floating point for x, y and r. I could try rounding to the nearest int when in the drawing code.

Answer 1

Are you doing anything else to the canvas before the drawCircle? This could happen if, for example you are scaling the canvas or transforming it before you draw the circle.
