Each library contains a set of pre-combined codes whose use reduces the time necessary to code. Libraries are especially useful for accessing pre-written codes that are repeatedly used, which saves users the time of having to write them from scratch every time. Python has over 137,000 ...
context.save() ; drawing codes… context.restore(); 5、变化路径 context.translate(x, y) //移动Canvas的原点到x,y处 context.rotate(angle) //按给定的弧度旋转,按顺时针旋转 默认原点是(0,0)处,如果设置成context.translate(10, 10),那么Canvas的原点就变成(10,10)了,rotate时也是以(10,10)点为...
