GD imagettfbbox problem

Recommended Posts

First of all, Hello all!

 

I have this problem:

I want to create an image sized perfectly to contain a specific text, so i use imagettfbbox function to find the width of the image, and then use imagettf starting from x=0 to draw the text.

So for example something like

print_r(imagettfbbox(50, 0, "./comic.ttf", "Hello"));

On my server it returns

Array ( [ 0] => -1 [1] => -1 [2] => 149 [3] => -1 [4] => 149 [5] => -56 [6] => -1 [7] => -56 )

So i consider the width of the text 149+1= 150, the problem is that 150 is actually the width of the text but only if you consider it from most left colored pixel to most right colored pixel. Cos when i make imagettftext starting from x=0 there is anyway a small offset to the right of some pixels before text starting, so the width i calculated is not enough, and it "cust out" my text.

I tried the same line of code on other server and it gives me

Array ( [ 0] => 2 [1] => 3 [2] => 159 [3] => 3 [4] => 159 [5] => -54 [6] => 2 [7] => -54 )

So in this case the width is 159-2=157 and this is exactly the width neccessary to contain my whole text, ofsets included!

Any ideas on what my server is doing wrong, and how to fix it? (Font files are the same)

Thank you :)
