Creating multiline text with GD is bit complicated, one of the issues I've ran to is how to set
line spacing, a normal feature in all type setting (even type writers). By default, line spacing
with imagettftext seems to be 150 % or more, too much for me anyhow. Thus I've used the
function below to get the lines closer to each other. By default, it appears to create 100 %
linespacing, but it has not been tested thoroughly.
null imagettfmultilinetext
(resource $image, float $size, float $angle, int $x, int $y, int $color, string $fontfile, string
$text , $spacing)
spacing is a coefficient, comparable to Line spacing in a word processors or graphics software,
causing a shift relative to font size in the line spacing
<?php
function imagettfmultilinetext($image, $size, $angle, $x, $y, $color, $fontfile, $text, $spacing=1)
{
$lines=explode("\n",$text);
for($i=0; $i< count($lines); $i++)
{
$newY=$y+($i * $size * $spacing);
imagettftext($image, $size, $angle, $x, $newY, $color, $fontfile, $lines[$i], $spacing);
}
return null;
}
?>
