Find which is smaller: `MaxWidth / w`

or `MaxHeight / h`

Then multiply `w`

and `h`

by that number

**Explanation:**

You need to find the scaling factor which makes the image fit.

To find the scaling factor, `s`

, for the width, then `s`

must be such that:

`s * w = MaxWidth`

.

Therefore, the scaling factor is `MaxWidth / w`

.

Similarly for height.

The one that requires the most scaling (smaller `s`

) is the factor by which you must scale the whole image.
