[SOLVED] ImageTTFText paragraph issue

[Asperon]

Is it possible to take text from a POST that is being written to an image using the GD ImageTTFText function and breaking it apart so that it writes like a paragraph. For example if you have "Welcome to the happiest place on earth" typed into the input text box and subinted but the width of the image it is being written too only is wide enough to hold "Welcome to the happiest", is there a function that automatically breaks text in the image to a second line?? or do I have write my own function for that?

[Asperon]

I guess no response means I need to program it to do that myself..

You would need to add a new line \n after X characters. Yes, you'll have to do some yourself

like this

<?php
$text = "Welcome to the happiest place on earth";

$textArray = explode('|', wordwrap($text,25,'|'));

$y = $firstLinePos;
foreach ($textArray as $txt) 
{
    imagettftext(..... $txt);
    $y += $lineHeight;
}
?>

thank you, though, it seems that I have another problem now, but I"m not sure why.

 

I have some math in my code that aligns my text where I want it, centers it and then indents.

 

The more characters the text is, with the explode and wordwrap, the farther to the right the text shifts.

 

<?php
//$ln1[0] = text
//$ln1[2] = font size

$box = ImageTTFBBox($ln1[2],0,$font,$ln1[0]);

$d = $box[2] - $box[0];

$align = $width/2 + 30 - $d/2;

$textArray = explode('|', wordwrap($ln1[0],25,'|'));

$y = 40;
foreach ($textArray as $txt) 
{
    ImageTTFText($im,$ln1[2],0,$align,$y,$color,$font,$txt);
    $y += $ln1[2] + 3;
}

?>

You need to calculate width and position each time thru the loop, for each line of text

[Asperon]

well I tried just sticking my calculations in the loop, but it gave me the same results, so guess I have to tweek them?

[Asperon]

lol I left the first set up so it still used that...it works more properly now, but its is staying aligned to the left, instead of center, thanks for your help.

[Asperon]

k, I got it, heres the reslult...thank you all for your help I really appreciate it

 

<?php

$textArray = explode('|', wordwrap($ln1[0],25,'|'));

$y = 40;
foreach ($textArray as $txt) 
{
    
    $box = ImageTTFBBox($ln1[2],0,$font,$txt);

    $d = $box[2] - $box[0];

    $align = $width/2 + 30 - $d/2;

    ImageTTFText($im,$ln1[2],0,$align,$y,$color,$font,$txt);
    $y += $ln1[2] + 3;


}
