note 101675 added to function.imagexbm

There are 2 errors on this page in the examples. No one points out that the width MUST be evenly divisible by 8 or you get a mess. The example is 120 wide which just accidentally is evenly divisible by 8, which will happen only 1 in 8 times, randomly. This issue is dealt with in the code below. Also, since xbm is not color but black and white, the example should not be showing color anything, but it does. The code below is for black and white, and it works great. I love your site!!! <?php header("Content-type: image/xbm"); $mytext = $_GET['mytext']; $fontsize = 5; $wide = imagefontwidth($fontsize) * strlen($mytext) + 20; $temp1=$wide/8; $temp2=round($wide/8); if ($temp1<>$temp2){$wide=($temp2 * 8) + 8;} $high = imagefontheight($fontsize) + 20; $picture = imagecreatetruecolor($wide,$high); $white = imagecolorallocate($picture,255,255,255); imagefill($picture,0,0,$white); $black=imagecolorallocate($picture, 0, 0, 0); imageline($picture, 0, 0, 0, $high, $black); imageline($picture, 0, 0, $wide, 0, $black); imageline($picture, $wide-1, 0, $wide-1, $high-1, $black); imageline($picture, 0, $high-1, $wide-1, $high-1, $black); imagestring($picture,$fontsize,10,10,$mytext,$black); imagexbm($picture); imagexbm($picture,"mytextpic.xbm"); imagedestroy($picture); ?> ---- Server IP: 69.147.83.197 Probable Submitter: 76.115.172.245 ---- Manual Page -- http://www.php.net/manual/en/function.imagexbm.php Edit -- https://master.php.net/note/edit/101675 Del: integrated -- https://master.php.net/note/delete/101675/integrated Del: useless -- https://master.php.net/note/delete/101675/useless Del: bad code -- https://master.php.net/note/delete/101675/bad+code Del: spam -- https://master.php.net/note/delete/101675/spam Del: non-english -- https://master.php.net/note/delete/101675/non-english Del: in docs -- https://master.php.net/note/delete/101675/in+docs Del: other reasons-- https://master.php.net/note/delete/101675 Reject -- https://master.php.net/note/reject/101675 Search -- https://master.php.net/manage/user-notes.php
