Width ImageString, the strings you draw are not automatically wrapped width the edge of the image. You may use this function to automatically wrap them:
function ImageStringWrap($image, $font, $x, $y, $text, $color, $maxwidth)
{
$fontwidth = ImageFontWidth($font);
$fontheight = ImageFontHeight($font);
if ($maxwidth != NULL) {
$maxcharsperline = floor($maxwidth / $fontwidth);
$text = wordwrap($text, $maxcharsperline, "\n", 1);
}
$lines = explode("\n", $text);
while (list($numl, $line) = each($lines)) {
ImageString($image, $font, $x, $y, $line, $color);
$y += $fontheight;
}
}
So, in particular, if you want to wrap a text with the edge of the Image, you may do:
ImageStringWrap($img, $font, 0, $y, $text, $color, ImageSX($img) );
