Text wrapping

[kristos80]

It would be a nice feature to make the text break in two lines if the available width is not enough for the text given and the font size or decrease automatically the font size in order to fit, but not under a specific limit (ex 8px) where it will break it in two lines.

Nevertheless is a really great library.

This is a rather complex request, and GD doesn't have anything built-in for it as far as I can tell. I would entertain a proper PR, but only if it doesn't bloat the library.

Furthermore, I don't think this should be a feature of the text method directly, but probably a separate method that uses text internally to achieve the desired effect.

Is there any update or progress about this request?

I've learned a bit more about how bounding boxes are calculated by GD thanks to #164. It's definitely possible to determine if the text will overlap a defined width, but I'm not sure how well it will perform.

The idea is:

• Accept a string of text.
• Determine the left/right position of the bounding box and calculate width.
• Is the start position + width > the defined width?
  • If not, draw the text.
  • If so, pop a word off the end of the string and try again.
• Start a new line and repeat the process with remaining words until the string is empty.

Things to consider:

• If a word can't be split, the text will overflow.
• Line height (in pixels) should be an argument. This can be handled correctly now thanks to Get imagettftext array back using text() method #164 and Text appears outside bounding box #165.

That said, I'm in the middle of another project at the moment and won't be able to tackle this right away. If anyone is interested in taking a stab at it, let me know!

This would be a great feature to have! +1

This can be useful, it is not the best solution but it can work very well in many cases.

$text  = '  Lorem ipsum dolor sit amet, consectetur adipiscing elit. Fusce ac scelerisque mi, eget facilisis eros.'.PHP_EOL;
$text .= '  Vestibulum vitae libero elementum, dictum nisi in, porttitor arcu. Nunc viverra eu tortor vitae rutrum.'.PHP_EOL;
$text .= '  Nullam in vulputate lorem. Nunc gravida tristique posuere. Maecenas vel bibendum augue.'.PHP_EOL;
$text .= '  Nunc ultricies velit ut justo ultrices, eu aliquet dolor luctus.';
$text  = wordwrap($text, 30, PHP_EOL, true);
$image->text($text, ....................

I am working on a function to do this.
With right, left, center alignment ...

I'm doing a test, in the final stage.
The results were very good.

Manual line break is also supported.
This is the text of my example, where I put manual line breaks "PHP_EOL"

$text  = "    Morbi eu iaculis  arcu. Cras sit amet elementum arcu, a consectetur erat. Pellentesque enec quam interdum, eleifend eros non, dapibus nisl.";
$text .= PHP_EOL;
$text .= "    Mauris mattis metus at lacus eleifend tempor in feugiat magna. Vivamus id condimentum justo, fermentum efficitur mi. ";
$text .= PHP_EOL;
$text .= "    Praesent volutpat libero at lacus aliquet, interdum lobortis ante lobortis.";

Fantastic work! This looks amazing. 😍

I'll review the source tomorrow or the next day. Apologies for the delay!
