Resize image and it's bounding box in x,y,w,h format

Question

我有一个宽度为 1980 和高度为 1080 的图像，其中 x =759，y = 786，w = 369，h = 100。我想将此图像转换为宽度 = 640 和高度 = 480。如何根据新的图像格式？

Answer 1

As you know the actual (W,H) and new image format (newW,newH) then

newX = (newW/W) * x

and do the same for other value...

Edit:

newY = (newH/H) * y

And the same for other value.
