[RESOLVED] image resize to fit a zone

[VisionsOfCody]

Hi

I've written an image resize script which works fine to re-scale an image to a fixed width or height whilst respecting the proportions

what i can't figure out is how to code it so that it will rescale the image to fit within a zone (like in Photoshop or Fireworks batches) - i keep going round in circles, lol

imagine that this is the simplified code :

function scaleToZone($old_w,$old_h,$zone_w,$zone_h){
	$new_w = ?;
	$new_h = ?;
}

where $zone_w and $zone_h are the maximum width and height of the zone

What would i need to put so that the image is scaled and both width and height fit in the zone but still keeping the proportions ?

thanks for any help you can give

In other words you want to retain the aspect ratio.

yes - that's exactly it - didn't know what it was called, lol

In the bsgrules solution I don't know why they want to add black pudding to the image

oh silly me, that's black padding

thanks
