英语语法分析

Can fabricate and joint together either bent or rect. pipe.

无论弯头、方管还是圆管都可制作接合。

I offset the values of the row and column by one to calculate the lower right portion of the rect.

用计算偏移行和列的数值使得矩形区域的右下角。

Any new shapes drawn after the translate function appears using the offset; so in this case, the rect function actually creates a square at 100, 100, 150, 150, as shown in Figure 1, cell a.

translate函数之后绘制的任何形状都会加上这个偏移量；所以在这里，rect函数实际上在坐标100,100,150,150上创建一个正方形，如图1的单元格a所示。
