小数学帮助图像调整大小所需 [英] Little Math-help for image resize needed

问题描述

我有一个价值X宽度和Y高度的图像。

I have an Image with the Value X width and Y height.

现在我想将高度设置为60px。

Now I want to set the height ever to 60px.

通过哪个计算我可以计算图像正确调整大小的高度？

With which calculation I can calculate the height that the image is correct resized?

推荐答案

我想你正试图保持纵横比。如果是这样，请使用以下内容：

I think you are trying to maintain aspect ratio. If so use the following:

ratio = orginialHeight / newHeight

ratio = orginialHeight / newHeight

newWidth = orginialWidth * ratio

newWidth = orginialWidth * ratio
