Hi,
I have the same problem since 2 weeks ago.
I edit to know which value has $h,
print('current height: '.$current_height);
print('ratio: '.$ratio);
$h = max( 1, (int) round( $current_height * $ratio ) );
and the print was this: current height: 105 ratio: 1 current height: 105 ratio: 0.77319587628866 current height: ratio: 0.97
So the last print current height is nothing, that’s why replay that there is no value encountered. I decide to make this solution:
// Very small dimensions may result in 0, 1 should be the minimum.
if($current_height === ''){ $current_height = 1;}
$w = max( 1, (int) round( $current_width * $ratio ) );
$h = max( 1, (int) round( $current_height * $ratio ) );
And works!
