初步将允许放大的比例设置为1-9之间，当然也可以修改程序使之可以放大到更大比例，但是这样计算量将会很大，慎用。程序启动后将会询问要放大的倍数，请输入1到9之间的数（可以是小数，比如3.14）。如果输入的放大比例不是1-9之间的数，程序不会执行，而是直接退出。-Preliminary permit to enlarge the ratio will be set to between 1-9, of course, can also modify the procedures to enable it to enlarge to a larger proportion, but this calculation will be a great caution. After the commencement of proceedings will be asked to enlarge multiples, please enter the 1-9 between the number (can be decimal, for example, 3.14). If you enter the zoom ratio is not a number between 1-9, the program will not be implemented, but rather a direct exit.
