How to change php imagestring font size.

[Parvinder]

I use below code to show png image from external website with variable text string on it. it works fine. But i  want to change the text size, make it bold and font family of this text string with centered text.

The code is

 

$my_img = imagecreatefrompng("http://example.com/images/widget.png");


$text_colour = imagecolorallocate( $my_img, 255, 255, 255 );
imagestring( $my_img, 5, 80, 14, "$count_user", $text_colour );


$angle = 90.0;
$rotated = imagerotate($my_img, $angle, 0);


header( "Content-type: image/png" );
imagepng( $rotated );
imagecolordeallocate( $text_color );
imagedestroy( $rotated );

Kindly help. Thanks in advance.

You'll need to use imagettftext instead: give it a path to a bold font (yes, the font itself must be bold) and whatever size you want.

 

For centering you'll need imagettfbbox to determine the size of the rendered text, then you can calculate the correct offset for imagettftext so that the text is placed in the center. Google has suggestions on how to do that.

It's a lot more flexible for sizes and family if you use imagettftext. To centre, get the size of the text using imagettfbbox and calculate where to put it.
