note 52965 added to function.imagecopyresampled

I tried this code from a previous post. <? ... $t_im = imageCreateTrueColor($t_wd,$t_ht); imageAntiAlias($t_im,true); imagealphablending($t_im, false); imagesavealpha($t_im,true); $transparent = imagecolorallocatealpha($t_im, 255, 255, 255, 0); for($x=0;$x<$t_wd;$x++) { for($y=0;$y<$t_ht;$y++) { imageSetPixel( $t_im, $x, $y, $transparent ); } } imageCopyResampled($t_im, $o_im, 0, 0, 0, 0, $t_wd, $t_ht, $o_wd, $o_ht); imagePNG($t_im, $image_name); ... ?> It seems that it is not working correctly. In my test the source picture in ImageCopyResampled() is smaller than the destination picture $t_im, the remaining part is white ! I changed transparent alpha channel to 127, and I tried to replace loops with imagefilledrectangle(). It works fine and these resource greedy loops are removed. Here is the code with my change. <? ... $t_im = imageCreateTrueColor($t_wd,$t_ht); imageAntiAlias($t_im,true); imagealphablending($t_im, false); imagesavealpha($t_im,true); $transparent = imagecolorallocatealpha($t_im, 255, 255, 255, 127); imagefilledrectangle($t_img, 0, 0, $t_wd, $t_ht, $transparent); imageCopyResampled($t_im, $o_im, 0, 0, 0, 0, $t_wd, $t_ht, $o_wd, $o_ht); imagePNG($t_im, $image_name); ... ?> ---- Manual Page -- http://www.php.net/manual/en/function.imagecopyresampled.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+52965 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+52965&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+52965&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+52965&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+52965&report=yes&reason=useless Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+52965&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+52965&report=yes Search -- http://master.php.net/manage/user-notes.php
