[SOLVED] Finding out size of TTF font in pixels.

[RoninStretch]

 

I'm trying to find out how to center the text I write on images using GD.

 

Im using imagettftext to write on the image. Which i give a point size for the font.

 

But imagettfbbox want's a pixel width of the font. :s

 

anyone?

What exactly are you trying to do? Did you look at the comments on the imagettfbbox page? There are a ton of helpful functions posted.

I looked yeah but i'm quite new and the advanced coding techniques they use make most of it illegible.

 

What i'm trying to do is just center my text.

 

So

$imageX = 100; // pixels
$fontwidth = 5; // pixels per character
$textlength = 10; // 10 characters
$textlengthpx = $fontwidth * $textlength;

$topleft = ($imageX - $textlengthpx) / 2;

 

or somethin...

 

I just need to know how to get the pixel width of a ttf font.

No, it wants the point size (how big do want it?) that you are using with the font then returns the x,y coordinates of the corners of a rectangle that would contain the text

if you guys say so i'll give it a bash..

 

but the manual says

 

"size - The font size in pixels "
