The app calculates the rect by multiplying the column and row position by the size of each chip.
这个计算通过行和列的位置和每个块的大小来得到矩形区域。
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。
The rect function draws a rectangle, with the first two points defining the location and the next two defining width and height, respectively.
rect函数可绘制一个矩形，并且前两个点定义位置，而后面两个点则分别定义宽度和高度。
For example, the code in Listing 1 draws a square using the rect function, then specifies a change to the coordinate system using translate.
例如，清单1所示代码使用rect函数绘制了一个正方形，然后使用translate修改坐标系统。
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。
The paint structure contains a rect data structure that has the smallest rectangle that completely encloses the update region and a flag that specifies whether the background has been erased.
绘图结构中包含了一个RECT数据结构，它包含了完全封闭更新区域的最小矩形以及一个标志，指明背景是否需要擦除。
Point and RECT are safe as they contain no Pointers or references to data stored in memory.
点和矩形是安全的，因为它们不包含指针或内存中存储的数据参考。
