note 126426 added to function.imagettfbbox

Pushing text around. I wanted to put various bits of text in the corners of an image so I created a function to accept a location in the image and then put a corner of the text (eg right,top) at that location. Rotation is not supported. Inputs to the function are fairly standard. The align parameter is two characters R|M|L (right, middle, top)for x alignment and T|M|B (top, middle, bottom) for y alignment; eg "LT" meaning left, top. Omitting the align parameter displays nothing. The function returns the size of the text block or false indicating failure. <?php function imagettfalign (&$im,$size,$x,$y,$col,$font,$text,$align='') { $box = imagettfbbox ($size,0,$font,$text) ; if (!$box) return false ; if ($align) { switch (strtoupper($align[0])) // X position { case 'L' : $tX = $x - $box[0] ; break ; case 'R' : $tX = $x - $box[2] ; break ; case 'M' : $tX = $x - $box[2]/2 ; break ; default : return false ; } switch (strtoupper($align[1])) // Y position { case 'B' : $tY = $y - $box[1] ; break ; case 'T' : $tY = $y - $box[7] ; break ; case 'M' : $tY = $y - $box[7]/2 ; break ; default : return false ; } if (!imagettftext ($im,$size,0,$tX,$tY,$col,$font,$text)) return false ; } $r[0]=abs($box[2]) ; $r[1]=abs($box[7]) ; return $r ; } ?> An example (excluding font declarations, etc) would be: <?php $im = @imagecreatetruecolor(400,200) ; $colBlack = imagecolorallocate($im,0, 0, 0); $xy = imagettfalign ($im,12,200,100,$colBlack,$ttFont,"The middle",'MM') ; ?> This will show "The middle" smack in the centre of the image. Finally, apologies for the non-standard indentation. It's just the way I've been doing it for years... ---- Server IP: 45.112.84.4 Probable Submitter: 45.112.85.242 (proxied: 45.130.58.202) ---- Manual Page -- https://php.net/manual/en/function.imagettfbbox.php Edit -- https://main.php.net/note/edit/126426 Del: integrated -- https://main.php.net/note/delete/126426/integrated Del: useless -- https://main.php.net/note/delete/126426/useless Del: bad code -- https://main.php.net/note/delete/126426/bad+code Del: spam -- https://main.php.net/note/delete/126426/spam Del: non-english -- https://main.php.net/note/delete/126426/non-english Del: in docs -- https://main.php.net/note/delete/126426/in+docs Del: other reasons-- https://main.php.net/note/delete/126426 Reject -- https://main.php.net/note/reject/126426 Search -- https://main.php.net/manage/user-notes.php
