php - Copy an Image with Drop Shadow and Tranparent Background -

-

i tried duplicate png image, has drop shadow (i.e. alpha channel) , transparent background. however, resulting image paints shadow , transparent background black. tried imagecopy , imagecopymerge; neither yielded valid results, aren't same original image.

preview of images.

$src = imagecreatefrompng('img_box3-bg.png');  /* using imagecopy. */ $dest = imagecreatetruecolor(116, 100); imagecopy($dest, $src, 0, 0, 0, 0, 116, 100); imagepng($dest, 'img_box3-bg.imagecopy.png'); imagedestroy($dest);  /* using imagecopymerge. */ $dest2 = imagecreatetruecolor(116, 100); imagecopymerge($dest2, $src, 0, 0, 0, 0, 116, 100, 100); imagepng($dest2, 'img_box3-bg.imagecopymerge.png'); imagedestroy($dest2);  imagedestroy($src);

help? beforehand.

something this:

$src = imagecreatefrompng('img_box3-bg.png');  /* using imagecopy. */ $dest = imagecreatetruecolor(116, 100);  // new imagesavealpha($dest, true); $transparent = imagecolorallocatealpha($dest, 0, 0, 0, 127); imagefill($dest, 0, 0, $transparent);  imagecopy($dest, $src, 0, 0, 0, 0, 116, 100);  header('content-type: image/png'); imagepng($dest); imagedestroy($dest);

i got following problem: i have object called tempscore game. this object blitted canvas renderer via copypixels method. object not display object. it's score-object (self made). score-object extends object called basicblitarrayobject. basicblitarrayobject extends eventdispatcher (therefore no display object). i tried apply several different tweenlite-plugins tempscore-object (i.e. transformaroundcenter, colormatrixfilter, etc.). nothing happens. absolutely nothing. sometimes error messages (when plugin requires display object , object not display object). far good. according greensock (maker of tweenlite) engine can tween numeric property of object. when plugin transformaroundcenter requires display object tweening have modify plugin working non-display object (tempscore). can't because it's way hard me. my game rests upon code: http://www.8bitrocket.com/book/ch11_blastermines.zip try apply tweenlite object called tempmine inside game class blastermines.
