image resize quality

[windandwaves]

Hi Folk

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

This is what I use:

$source = imagecreatefrom jpeg($filename) ;
$thumb = imagecreatetrue color($w[$portrait][$j],$h[$portrait][$j]);
imagealphablend ing($thumb, false);
$source = @imagecreatefro mjpeg($filename );
imagecopyresize d($thumb, $source, 0, 82, 0, 0, $w[$portrait][$j],
$h[$portrait][$j], $width, $height);
@imagejpeg($thu mb, $filename);

And the images come out rather pixilated...

TIA

You're loading your source image twice.

Re: image resize quality

Use imagecopyresamp led instead of imagecopyresize d and get rid of
imagealphablend ing unless you really need it.
