UIBezierPath lineWidth
@property(nonatomic) CGFloat lineWidth
Discussion of [UIBezierPath lineWidth]
The line width defines the thickness of the receiver's stroked path. A width of 0 is interpreted as the thinnest line that can be rendered on a particular device. The actual rendered line width may vary from the specified width by as much as 2 device pixels, depending on the position of the line with respect to the pixel grid and the current anti-aliasing settings. [UIBezierPath lineWidth] The width of the line may also be affected by scaling factors specified in the current transformation matrix of the active graphics context.
The default line width is 1.0.
