Note Submitter: denis at ryzhkov dot org ---- Thanks for helping comments on imagecreatefrompng vs alpha. Here is my working result, hope it will help somebody: <?php $png_fn = 'pal_bk.png'; // http://entropymine.com/jason/testbed/pngtrans/pal_bk.png $png = imagecreatefrompng($png_fn); // 1. direct imagepng($png, 'result.png'); // has alpha! // 2. with imagecopy $png_size = getimagesize($png_fn); $width = $png_size[0]; $height = $png_size[1]; $canvas = imagecreatetruecolor($width, $height); imagesavealpha($canvas, true); // important $max_alpha = imagecolorallocatealpha($canvas, 0, 0, 0, 127); imagefill($canvas, 0, 0, $max_alpha); // important imagecopy( $canvas, $png, 0, 0, 0, 0, $width, $height ); imagepng($canvas, 'result.png'); // has alpha! ?>
