连续绘制图块

现在你已经有了绘制路径的逻辑，下一步就是弄清楚如何在每一行中绘制图块。在下图中，显示了两种情况：一行与路径中心的偏移量等于 0.0，另一行的偏移量不等于零。请看一下图表，然后阅读下面的伪代码。

Set up variables for StartPoint, angp90, angm90, and so on.

Set the variable FirstCenterPoint to the StartPoint + offset amount 
    (which may be 0.0).

Set the initial value of TileCenterPt to FirstCenterPoint.

(Comment: Begin by drawing the circles in the angp90 direction.)
While the distance from the StartPoint to the TileCenterPt is less than the HalfWidth:
    Draw a circle (adding to the accumulating list of circles).
    Set TileCenterPt to the next tile space increment in the angp90
    direction.
End While

Reset the TileCenterPoint to the FirstCenterPoint + the tile space increment at angm90.

While the distance from the StartPoint to the TileCenterPt is less than the HalfWidth:
    Draw a circle (adding to the accumulating list of circles).
    Set TileCenterPt to the next tile space increment in the angm90
    direction.
End While

Return the list of circles.
