Contrary to the example code provided for this function, if you are manipulating an image with an alpha channel that you want to maintain, you have to turn image alpha blending off BEFORE doing an operations on the image, not afterwards as the example instructs. If you do it afterwards like in the example, all alpha channel data will be discarded and leave you with an image imposed on a black background instead of "transparency". ---- Server IP: 69.147.83.199 Probable Submitter: 83.180.245.84 ---- Manual Page -- http://php.net/manual/en/function.imagesavealpha.php Edit -- https://master.php.net/note/edit/111560 Del: integrated -- https://master.php.net/note/delete/111560/integrated Del: useless -- https://master.php.net/note/delete/111560/useless Del: bad code -- https://master.php.net/note/delete/111560/bad+code Del: spam -- https://master.php.net/note/delete/111560/spam Del: non-english -- https://master.php.net/note/delete/111560/non-english Del: in docs -- https://master.php.net/note/delete/111560/in+docs Del: other reasons-- https://master.php.net/note/delete/111560 Reject -- https://master.php.net/note/reject/111560 Search -- https://master.php.net/manage/user-notes.php
