Re^3: GD colorAllocate not changing colour

in thread GD colorAllocate not changing colour

The problem may be here

$image->copy($resize, 0, 0, 0, ($newh - 450) / 2, 600, 450);

gd does nice cropping to viewports but this one may be too much if $newh<450

if ($newh<450) { 
  $image->copy($resize, 0, (450-$newh ) / 2, 0,0, 600, $newh);
  }
else {
  $image->copy($resize, 0, 0, 0, ($newh - 450) / 2, 600, 450);  
  ]

Trying to copy from outside the bounds of the src image may have introduced the black, just a guess

Although I suspect it was an educated guess at the very least :) Either way, that has worked! Thank you very much huck. Because the problem was only appearing with a real picture as the image and not a pattern created in GD, it seemed to be a palette issue. The effort had been looking there rather than the way the foreground image is placed on the background...	[reply]
