    <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>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
