note 77098 added to function.imagecolortransparent

To resize transparent PNG (if image is transparent & ImageColorTransparent() returns -1): 1) create a new image with the new sizes 2) make the new image all transparent 3) turn off the alpha blending for the new image (to keep the alpha channel when copy data) 4) do copyresampled or copyresized into new image PHP code: // 1 $im2 = ImageCreateTrueColor($w, $h); // 2 ImageColorTransparent($im2, ImageColorAllocate($im2, 0, 0, 0)); // 3 ImageAlphaBlending($im2, false); // 4 ImageCopyResampled($im2, $im, 0, 0, 0, 0, $w, $h, ImageSX($im), ImageSY($im)); or see this http://alexle.net/archives/131 ---- Server IP: 69.147.83.197 Probable Submitter: 217.21.216.155 ---- Manual Page -- http://www.php.net/manual/en/function.imagecolortransparent.php Edit -- https://master.php.net/note/edit/77098 Del: integrated -- https://master.php.net/note/delete/77098/integrated Del: useless -- https://master.php.net/note/delete/77098/useless Del: bad code -- https://master.php.net/note/delete/77098/bad+code Del: spam -- https://master.php.net/note/delete/77098/spam Del: non-english -- https://master.php.net/note/delete/77098/non-english Del: in docs -- https://master.php.net/note/delete/77098/in+docs Del: other reasons-- https://master.php.net/note/delete/77098 Reject -- https://master.php.net/note/reject/77098 Search -- https://master.php.net/manage/user-notes.php
