"""This method writes the QR code out as an EPS document. The
code is drawn by only writing the data modules corresponding to a 1.
They are drawn using a line, such that contiguous modules in a row
are drawn with a single line.
The *file* parameter is used to specify where to write the document
to. It can either be a writable (text) stream or a file path.
The *scale* parameter sets how large to draw a single module. By
default one point (1/72 inch) is used to draw a single module. This may
make the code to small to be read efficiently. Increasing the scale
will make the code larger. This method will accept fractional scales
(e.g. 2.5).
The *module_color* parameter sets the color of the data modules. The
*background* parameter sets the background (page) color to use. They
are specified as either a triple of floats, e.g. (0.5, 0.5, 0.5), or a
triple of integers, e.g. (128, 128, 128). The default *module_color* is
black. The default *background* color is no background at all.
The *quiet_zone* parameter sets how large to draw the border around
the code. As per the standard, the default value is 4 modules.
Examples:
>>> qr = pyqrcode.create('Hello world')
>>> qr.eps('hello-world.eps', scale=2.5, module_color='#36C')
>>> qr.eps('hello-world2.eps', background='#eee')
>>> out = io.StringIO()
>>> qr.eps(out, module_color=(.4, .4, .4))

"""这个实例方法是把二维码写成一种 EPS 文档。
二维码的绘制只把数据块写成1。数据块绘制成行，这样一行里相邻的数据块
都会绘制在单行里。
其中 *file* 参数是用来描述文档的存储位置用的。
参数值即可以是可写的（文本）流数据，也可以是一个文件路径。
其中 *scale* 参数是设置一个数据块绘制多大用的。
参数默认值是1点（1/72 英寸）绘制一个数据块。这可能让二维码太小无法有效读取。
增加标量参数值会让二维码变大。这个参数值可以是分数标量值（例如，2.5）。
其中 *module_color* 参数是设置数据块的颜色用的。
其中 *background* 参数是设置背景色（页面颜色）用的。
这两个与颜色有关的参数值即可以描述成三个浮点数形式 (0.5, 0.5, 0.5)，
也可以描述成三个整数形式 (128, 128, 128)。
其中 *module_color* 参数值默认是黑色， *background* 参数默认值透明色。
其中 *quiet_zone* 参数是设置二维码边界多宽用的。
由于二维码标准，默认值是4个数据块。
