note 72393 added to function.imagecopy

Here is an upgrade of that cool wave function: Double the size of the image, wave it, then resample it down again. This makes even nicer, anti aliased waves. // So easy and nice! function wave_region($img, $x, $y, $width, $height,$amplitude = 4.5,$period = 30) { // Make a copy of the image twice the size $mult = 2; $img2 = imagecreatetruecolor($width * $mult, $height * $mult); imagecopyresampled ($img2,$img,0,0,$x,$y,$width * $mult,$height * $mult,$width, $height); // Wave it for ($i = 0;$i < ($width * $mult);$i += 2) { imagecopy($img2,$img2, $x + $i - 2,$y + sin($i / $period) * $amplitude, // dest $x + $i,$y, // src 2,($height * $mult)); } // Resample it down again imagecopyresampled ($img,$img2,$x,$y,0,0,$width, $height,$width * $mult,$height * $mult); imagedestroy($img2); } To use it in a full image: wave_region ($oImage,0,0,imagesx($oImage),imagesy($oImage)); ---- Server IP: 69.147.83.197 Probable Submitter: 75.80.185.96 ---- Manual Page -- http://www.php.net/manual/en/function.imagecopy.php Edit -- https://master.php.net/note/edit/72393 Del: integrated -- https://master.php.net/note/delete/72393/integrated Del: useless -- https://master.php.net/note/delete/72393/useless Del: bad code -- https://master.php.net/note/delete/72393/bad+code Del: spam -- https://master.php.net/note/delete/72393/spam Del: non-english -- https://master.php.net/note/delete/72393/non-english Del: in docs -- https://master.php.net/note/delete/72393/in+docs Del: other reasons-- https://master.php.net/note/delete/72393 Reject -- https://master.php.net/note/reject/72393 Search -- https://master.php.net/manage/user-notes.php
