函数文档

applyFillPropertiesToContext:atZoomScale:

- (void) applyFillPropertiesToContext:		(CGContextRef)	context
atZoomScale:		(BMKZoomScale)	zoomScale

应用画刷属性

参数

context	CGContext对象
zoomScale	当前的zoomScale

applyStrokePropertiesToContext:atZoomScale:

- (void) applyStrokePropertiesToContext:		(CGContextRef)	context
atZoomScale:		(BMKZoomScale)	zoomScale

应用画笔属性

参数

context	CGContext对象
zoomScale	当前的zoomScale

createPath

- (void) createPath

生成要绘制的path，子类需要重写此函数，并且对path属性赋值：self.path = newPath;

fillPath:inContext:

- (void) fillPath:		(CGPathRef)	path
inContext:		(CGContextRef)	context

填充path

参数

path	要绘制的CGPath
context	CGContext对象

invalidatePath

- (void) invalidatePath

刷新path，调用该函数将会使已经缓存的path失效，将会重新调用createPath来生成新的path对象

strokePath:inContext:

- (void) strokePath:		(CGPathRef)	path
inContext:		(CGContextRef)	context

绘制path

参数

path	要绘制的CGPath
context	CGContext对象
