trq Posted March 1, 2008 Share Posted March 1, 2008 Can't see why you couldn't do it with imagearc, Ive never tried it though so couldn't really help. Quote Link to comment Share on other sites More sharing options...

bobinindia Posted March 1, 2008 Author Share Posted March 1, 2008 So here is the code. I want to imagerotate() each character from imagechar() before it is printed. Any suggestions? <?php $string = '1 2 3 4 5 6 7 8 9 A B C D E F G'; $font_size = 5; $width=imagefontwidth($font_size)*strlen($string); $height=imagefontheight($font_size)*2; $img = imagecreate($width,$height); $bg = imagecolorallocate($img,225,225,225); $black = imagecolorallocate($img,0,0,0); $len=strlen($string); $r = 100; for($i=0;$i<$len;$i++) { $xpos=$i*imagefontwidth($font_size); $ypos=6; //somehow rotate in here below imagechar($img,$font_size,$xpos,$ypos,$string,$black); $string = substr($string,1); } header("Content-Type: image/gif"); imagegif($img); imagedestroy($img); ?> Quote Link to comment Share on other sites More sharing options...
helraizer Posted March 1, 2008 Share Posted March 1, 2008 Umm.. I think you'll have to improvise on this one. There is no easy way to create arced text as a whole, as such that I know of.. But with imagettftext: imagettftext ( resource $image , float $size , float $angle , int $x , int $y , int $color , string $fontfile , string $text ) the third element is float angle, which you can set to face the character facing from 0 to 359 degrees. If you have $string, you can use $str_split($string, 1) to split the string up into one character chunks. Then use imagettftext for all of them, using a slightly different angle for each and a slightly different x and y co-ord. Will give an arced effect, with experimenting. Hope that helps?

bobinindia Posted March 1, 2008 Author Share Posted March 1, 2008 So here is the solution as it must be shared. Thank you all for your suggestions. <?php //This works with GD2 and PHP 5. $text = "SAI BABA SAI BABA SAI BABA "; $image = imagecreatefromjpeg("frontrange.jpeg"); $white = imagecolorallocate($image,255,255,255); imagefill($image,0,0,$white); $red = imagecolorallocate($image,255,0,0); $degrees = (360/strlen($text)); for ($i=0;$i<strlen($text);$i++) { $a = ($degrees*$i)+180; $cos = cos(deg2rad($a)); $sin = sin(deg2rad($a)); $x = 0; $y = 70; $xt = round($cos*($x) - $sin*($y)); $yt = round($sin*($x) + $cos*($y)); imagettftext($image,20,180-($a),110+$xt,100+$yt,$red,"Fonts/Palatino",$text[$i]); } header("Content-type: image/jpeg"); imagejpeg($image,"",100); imagedestroy($image); ?> Quote Link to comment Share on other sites More sharing options...
Barand Posted March 1, 2008 Share Posted March 1, 2008 You can get rid of the saw-tooth effect on the character baselines by getting the angle at the midpoint of the characters' baselines rather than at the bottom left. Quote Link to comment Share on other sites More sharing options...
bobinindia Posted March 12, 2008 Author Share Posted March 12, 2008 Hi Barand, How do I get the angle at the midpoint of the characters baselines as you suggested? imagettftext() by default sets the angle from the bottom left. Is there a way around this? Quote Link to comment Share on other sites More sharing options...
Barand Posted March 12, 2008 Share Posted March 12, 2008 My code, that I pointed you towards earlier in this thread, does exactly that. Quote Link to comment Share on other sites More sharing options...
