note 63629 added to function.imagesetpixel

This functions is very useful if you want to replace a specific color with another color. This can be used the same way as str_replace, so i call it img_replace :) I wonder if there will be anything like img_preg_replace ;) <?php function img_replace($from,$to,&$im) { for ( $xx = 0; $xx < imagesx($im); $xx++ ) { for ( $yy = 0; $yy < imagesy($im); $yy++ ) { $cur=imagecolorat($im,$xx,$yy); if ( $cur == $from ) { imagesetpixel($im,$xx,$yy,$to); } } } } // Create a 500x500 image $image=imagecreatetruecolor(500,500); // Fill $col=imagecolorallocate($image,255,255,0); imagefilledrectangle( $image,0,0,imagesx($image), imagesy($image), $col ); // Print a red rectangle $col=imagecolorallocate($image,255,0,0); imagefilledrectangle($image,100,100,200,200,$col); // Replaces all Red to Bluish :) img_replace( imagecolorallocate($image,255,0,0), imagecolorallocate($image,0,100,255), $image ); header("Content-Type: image/png"); imagepng($image); ?> === http://wykis.com/ ---- Server IP: 84.18.202.180 Probable Submitter: 84.9.161.115 ---- X-Spam-Status: No, hits=3.1 required=5.0 tests=DATE_MISSING,FROM_NO_LOWER autolearn=no version=2.64 ---- Manual Page -- http://www.php.net/manual/en/function.imagesetpixel.php Edit -- http://master.php.net/note/edit/63629 Del: integrated -- http://master.php.net/note/delete/63629/integrated Del: useless -- http://master.php.net/note/delete/63629/useless Del: bad code -- http://master.php.net/note/delete/63629/bad+code Del: spam -- http://master.php.net/note/delete/63629/spam Del: non-english -- http://master.php.net/note/delete/63629/non-english Del: in docs -- http://master.php.net/note/delete/63629/in+docs Del: other reasons-- http://master.php.net/note/delete/63629 Reject -- http://master.php.net/note/reject/63629 Search -- http://master.php.net/manage/user-notes.php
