note 82032 added to function.imagecolortransparent

@wesley gunn: Thank you very, very much for the code to determine if a PNG is 24 or 32-bit :) Here's an improved version in one line without using a file-handle <?php $is_alpha = ((ord ( file_get_contents ($filename, false, null, 25, 1) ) & 6) & 4) == 4; ?> Gives true for a PNG with alpha, false otherwise. This cannot detect 8-bit PNGs with transparency, but you could do that by searching the file contents for the presence of "PLTE" *AND* "tRNS". ---- Server IP: 92.48.74.199 Probable Submitter: 82.44.33.144 ---- Manual Page -- http://www.php.net/manual/en/function.imagecolortransparent.php Edit -- https://master.php.net/note/edit/82032 Del: integrated -- https://master.php.net/note/delete/82032/integrated Del: useless -- https://master.php.net/note/delete/82032/useless Del: bad code -- https://master.php.net/note/delete/82032/bad+code Del: spam -- https://master.php.net/note/delete/82032/spam Del: non-english -- https://master.php.net/note/delete/82032/non-english Del: in docs -- https://master.php.net/note/delete/82032/in+docs Del: other reasons-- https://master.php.net/note/delete/82032 Reject -- https://master.php.net/note/reject/82032 Search -- https://master.php.net/manage/user-notes.php
