Image scaling by Width & Height constant - preserve aspect ratio

Hi,

I'm looking for an algorithm to resize an image of arbitrary size to a
"fixed" / required width and height.

For example, my application requires that images be no larger than 440 pixel
(height) x 780 (wide)

So the "preferred size" would be 440 x 780

If an image is too large, either by width or height it should be resized
until less than or equal to 440 x 780 and preserve aspect ratio.

Thanks for any tips.
