POPHP GD: Blur for transparent image

copied!<p>I am trying to create the silhouette of PNG image with transparencies. Here is my code</p> <pre><code> //file that i am working with $file='http://www.google.com/mapfiles/turkey.png'; $im =imagecreatefrompng($file); imagealphablending($im, false); imagesavealpha($im, true); $imw =imagesx($im); $imh =imagesy($im); //turkey body color $bodycolor=imagecolorallocatealpha($im, 144, 144, 144, 50); //imageholder $imnew =imagecreatetruecolor($imh, $imh); imagealphablending($imnew, false); imagesavealpha($imnew, true); $transparent_color=imagecolorallocatealpha($imnew, 0, 0, 0, 127); imagecolortransparent($imnew, $transparent_color); imagefilledrectangle($imnew, 0, 0, $imh, $imh, $transparent_color); for ($i=0; $i > 24; //all not transparent pixels are copied to imageholder if ($alpha != 127) { imagesetpixel($imnew, $i, $j, $bodycolor); } } } //blur filter imagefilter($imnew, IMG_FILTER_GAUSSIAN_BLUR); imagefilter($imnew, IMG_FILTER_GAUSSIAN_BLUR); imagefilter($imnew, IMG_FILTER_GAUSSIAN_BLUR); header ("Content-type: image/png"); imagepng ($imnew); imagedestroy ($imnew); ?> </code></pre> <p>So, I need to get the silhouette ot the turkey with blurred edges. What I get now looks like <a href="http://yfrog.com/5edownloadnap" rel="nofollow noreferrer" title="this">link text</a>. I need edges to be blurred "outside", so the farther the pixel was from edge, the more transparent it was with the same rbg. And imagefilter also lifts the turkey a bit :) Please help, I am trying to solve this for days. </p>
