note 113563 added to function.imagettftext

For your general edification: The following drop-in function will place a block of fully justified text onto a GD image. It is a little CPU heavy, so I suggest caching the output rather than doing it on-the-fly. Arguments: $image - the GD handle of the target canvas $size - text size $angle - slope of text (does not work very well), leave at 0 for horizontal text $left - no. of pixels from left to start block $top - no. of pixels from top to start block $color - handle for colour (imagecolorallocate result) $font - path to .ttf font $text - the text to wrap and justify $max_width - the width of the text block within which the text should be wrapped and fully justified $minspacing - the minimum number of pixels between words $linespacing - a multiplier of line height (1 for normal spacing; 1.5 for line-and-a-half etc.) eg. $image = ImageCreateFromJPEG( "sample.jpg" ); $cor = imagecolorallocate($image, 0, 0, 0); $font = 'arial.ttf'; $a = imagettftextjustified($image, 20, 0, 50, 50, $color, $font, "Shree", 500, $minspacing=3,$linespacing=1); header('Content-type: image/jpeg'); imagejpeg($image,NULL,100); function imagettftextjustified(&$image, $size, $angle, $left, $top, $color, $font, $text, $max_width, $minspacing=3,$linespacing=1) { $wordwidth = array(); $linewidth = array(); $linewordcount = array(); $largest_line_height = 0; $lineno=0; $words=explode(" ",$text); $wln=0; $linewidth[$lineno]=0; $linewordcount[$lineno]=0; foreach ($words as $word) { $dimensions = imagettfbbox($size, $angle, $font, $word); $line_width = $dimensions[2] - $dimensions[0]; $line_height = $dimensions[1] - $dimensions[7]; if ($line_height>$largest_line_height) $largest_line_height=$line_height; if (($linewidth[$lineno]+$line_width+$minspacing)>$max_width) { $lineno++; $linewidth[$lineno]=0; $linewordcount[$lineno]=0; $wln=0; } $linewidth[$lineno]+=$line_width+$minspacing; $wordwidth[$lineno][$wln]=$line_width; $wordtext[$lineno][$wln]=$word; $linewordcount[$lineno]++; $wln++; } for ($ln=0;$ln<=$lineno;$ln++) { $slack=$max_width-$linewidth[$ln]; if (($linewordcount[$ln]>1)&&($ln!=$lineno)) $spacing=($slack/($linewordcount[$ln]-1)); else $spacing=$minspacing; $x=0; for ($w=0;$w<$linewordcount[$ln];$w++) { imagettftext($image, $size, $angle, $left + intval($x), $top + $largest_line_height + ($largest_line_height * $ln * $linespacing), $color, $font, $wordtext[$ln][$w]); $x+=$wordwidth[$ln][$w]+$spacing+$minspacing; } } return true; } ---- Server IP: 64.71.164.2 Probable Submitter: 122.168.198.236 ---- Manual Page -- http://php.net/manual/en/function.imagettftext.php Edit -- https://master.php.net/note/edit/113563 Del: integrated -- https://master.php.net/note/delete/113563/integrated Del: useless -- https://master.php.net/note/delete/113563/useless Del: bad code -- https://master.php.net/note/delete/113563/bad+code Del: spam -- https://master.php.net/note/delete/113563/spam Del: non-english -- https://master.php.net/note/delete/113563/non-english Del: in docs -- https://master.php.net/note/delete/113563/in+docs Del: other reasons-- https://master.php.net/note/delete/113563 Reject -- https://master.php.net/note/reject/113563 Search -- https://master.php.net/manage/user-notes.php
