image resampling

[alexandre damiron]

That function:

function
resizeImage($de fsize,$newsize, $dX,$dY,$bgcolo r,$newname,$fil eformat,$fQuali ty)
{
$firstimage = imagecreate($de fsize[0],$defsize[1]);
imagecoloralloc ate($firstimage , $bgcolor[0], $bgcolor[1], $bgcolor[2]);
$newimage = imagecreatetrue color($defsize[0],$defsize[1]);
imagecopy ($newimage,$fir stimage,0,0,0,0 ,$defsize[0],$defsize[1]);
$image = imagecreatefrom string ($GLOBALS['filestr']);
//$image = imagecreatefrom jpeg($newname);

imagecopyresamp led($newimage,$ image,$dX,$dY,0 ,0,$newsize[0],$newsize[1],$image,
$GLOBALS['tmpsize'][1]);
if ($fileformat == "png") {
imagepng ($newimage, $newname);
$newtype = "image/x-png";
} else {
imagejpeg ($newimage, $newname, $fQuality);
$newtype = "image/pjpeg";
}
imagedestroy ($newimage);
return $newtype;
}

give me bad results, quality is very bad

- how to improve that-
- why $image = imagecreatefrom string ($GLOBALS['filestr']); is that
the best way ?

Re: image resampling

probably the reason can be here - imagecopy()
try to change it to imagecopyresamp led() because imagecopyresamp led()
do the same thing but smoothly
