note 82990 added to function.imagepsbbox

I have a given image width and need to render a long string on that image. By using the following function I'm, able to get an array of strings which each will fit into the images width. It might need a lot of CPU time, but it's cool: // Function to return an Array of Strings // Arguments: String to be wrapped, maximum width in pixels of each line, font and fontsize function imgwordwrap($s, $maxWidth, $font, $size) { // Make an empty ArrayList $a = array(); $w = 0; // Accumulate width of chars $i = 0; // Count through chars $rememberSpace = 0; // Remember where the last space was // As long as we are not at the end of the String while ($i < strlen($s)) { // Current char $c = substr($s, $i, 1); $bb = imagepsbbox($c, $font, $size); // calculate width $w += abs($bb[3])-abs($bb[1]); // accumulate width if ($c == ' ') $rememberSpace = $i; // Are we a blank space? if ($w > $maxWidth) { // Have we reached the end of a line? $sub = substr($s,0,$rememberSpace); // Make a substring // Chop off space at beginning if (substr($sub,0,1)==' ') $sub = substr($sub,1); // Add substring to the array $a[] = $sub; // Reset everything $s = substr($s,$rememberSpace); $i = 0; $w = 0; } else { $i++; // Keep going! } } // Take care of the last remaining line trim($s); if (substr($s,0,1)==' ') $s = substr($s,1); $a[] = $s; return $a; } ---- Server IP: 217.13.201.10 Probable Submitter: 62.206.116.182 ---- Manual Page -- http://www.php.net/manual/en/function.imagepsbbox.php Edit -- https://master.php.net/note/edit/82990 Del: integrated -- https://master.php.net/note/delete/82990/integrated Del: useless -- https://master.php.net/note/delete/82990/useless Del: bad code -- https://master.php.net/note/delete/82990/bad+code Del: spam -- https://master.php.net/note/delete/82990/spam Del: non-english -- https://master.php.net/note/delete/82990/non-english Del: in docs -- https://master.php.net/note/delete/82990/in+docs Del: other reasons-- https://master.php.net/note/delete/82990 Reject -- https://master.php.net/note/reject/82990 Search -- https://master.php.net/manage/user-notes.php
