我正在尝试获取图像的最左下角(x,y)坐标。我这样做是为了能够在左下角用不同大小的图片写文字。下面是代码。能否请你帮忙?
<?php
$white = imagecolorallocate($image2, 255, 255, 255);
$grey = imagecolorallocate($image2, 128, 128, 128);
$black = imagecolorallocate($image2, 0, 0, 0);
$textsize = 30;
$size = imagettfbbox($textsize, 0, $font, $text);
$xsize = abs($size[0]) + abs($size[2]);
$ysize = abs($size[5]) + abs($size[1]);
$image2size = getimagesize("image2.jpg");
$textleftpos = round(($image2size[0] - $xsize) / 2);
$texttoppos = round(($image2size[1] + $ysize) / 2);
imagettftext($image2, $textsize, 0, $textleftpos, $texttoppos, $white, $font, $text);
imagejpeg($image2, "image3.jpg");
?>
