image resize quality

[windandwaves]

Hi Folk

I was just wondering if you do any "thumbnailing" (imagecopyresized) of
images and if you have noticed that the quality is not always that great.

This is what I use:

$source = imagecreatefromjpeg($filename);
$thumb = imagecreatetruecolor($w[$portrait][$j],$h[$portrait][$j]);
imagealphablending($thumb, false);
$source = @imagecreatefromjpeg($filename);
imagecopyresized($thumb, $source, 0, 82, 0, 0, $w[$portrait][$j],
$h[$portrait][$j], $width, $height);
@imagejpeg($thumb, $filename);

And the images come out rather pixilated...

TIA

You're loading your source image twice.

Use imagecopyresampled instead of imagecopyresized and get rid of
imagealphablending unless you really need it.
