推荐答案

这没有任何实际意义感觉，因为你无法保存并以A4尺寸存档。

A4是纸张尺寸 - 210 x 297毫米 - 与文件的尺寸无关。打印文件时，它只是一个相关的尺寸，然后它受打印机/打印机驱动程序的控制。仅当文件包含可打印信息时才有意义。例如，什么是A4尺寸的AVI文件？它无法打印，因为它是一系列动态图像，而且打印毫无意义。 A4对于显示器而言毫无意义，因为毫米与屏幕像素之间没有直接关联 - 这取决于当时使用的实际屏幕。



我认为你需要坐下来重新思考你想要实现的目标，并更好地了解你想要保存的内容和原因。

That doesn't make any real sense, because you can't "save" and file in "A4 size".
A4 is a paper size - 210 x 297 mm - and bears no relation to the "size" of a file. It is only a relevant dimension when the file is printed, and then it is under the control of the printer / printer driver. It is only relevant then when the file contains printable information. For example, what is a AVI file "at A4 size"? It can't be printed, because it is a series of moving images, and printing makes no sense. A4 means nothing as far as a monitor is concerned, because there is no direct correlation between millimeters and on-screen pixels - it depends on the actual screen in use at the time.

I think you need to sit down and re-think what you are trying to achieve and work out a better idea of exactly what you want to save and why.
