note 114675 added to function.imagepalettetotruecolor

The backwards compatibility example does not preserve transparency. You must first wipe out the default black background on the new image: <?php // Backwards compatiblity if (!function_exists('imagepalettetotruecolor')) { function imagepalettetotruecolor(&$src) { if (imageistruecolor($src)) { return true; } $dst = imagecreatetruecolor(imagesx($src), imagesy($src)); imagealphablending($dst, false);//prevent blending with default black $transparent = imagecolorallocatealpha($new_image, 255, 255, 255, 127);//change the RGB values if you need, but leave alpha at 127 imagefilledrectangle($dst, 0, 0, $imagesx($src), imagesy($src), $transparent);//simpler than flood fill imagealphablending($dst, true);//restore default blending imagecopy($dst, $src, 0, 0, 0, 0, imagesx($src), imagesy($src)); imagedestroy($src); $src = $dst; return true; } } ?> ---- Server IP: 72.52.91.14 Probable Submitter: 150.101.23.241 ---- Manual Page -- http://php.net/manual/en/function.imagepalettetotruecolor.php Edit -- https://master.php.net/note/edit/114675 Del: integrated -- https://master.php.net/note/delete/114675/integrated Del: useless -- https://master.php.net/note/delete/114675/useless Del: bad code -- https://master.php.net/note/delete/114675/bad+code Del: spam -- https://master.php.net/note/delete/114675/spam Del: non-english -- https://master.php.net/note/delete/114675/non-english Del: in docs -- https://master.php.net/note/delete/114675/in+docs Del: other reasons-- https://master.php.net/note/delete/114675 Reject -- https://master.php.net/note/reject/114675 Search -- https://master.php.net/manage/user-notes.php
