读取dst文件（绣花文件类型）并绘出图形。

内容包括，以3字节一字符串组读取，并以dst文件读写方法进行换算，主要是直接读取每字节里的每1位进行计算，计算出x位移和y位移，然后换成屏幕画线需要的结束点，然后2点画线，再次循环则将上次的结束点赋给起始点，再次读取3字节进行计算。。。。

可重用代码：读取地址进行每字节的每1位的计算。

PS：dst文件可以用田岛软件进行编写。-read dst (embroidery file types) and draws graphics. The contents include, for a three-byte string group read, and to read and write documents dst conversion method, main is a direct read every byte of every Lane a calculated, the calculated displacement x and y displacement, screen painting then changed to the end line, then two dotted line again last cycle will end points assigned to the threshold, 3 byte read again calculated. . . . Reusable code : read addresses every byte of every one of calculation. PS : dst document TAJIMA software can be used for the preparation.
