有没有办法用这种方法计算spl文件的页数？
Is there a way to calculate page count of the spl file with this method?
推荐答案
您犯的第一个错误是程序文件中的路径。如果真的需要，请使用一些临时目录。
如果你想要页面大小，你必须运行打印命令。我找到了关于打印的好文章，它将向您展示有关打印的所需基础知识，应该可以帮助您解决你的问题。
The first mistake you make is to the path in Program Files. Use some temp directory if really needed.
If you want the page size, you must run the print commands. I found the nice article about printing which will show you the needed basics about printing and should help you solving your problem.
