怎么在一个图片上打上标签
<?php
header("Content-type: image/jpeg");
$img1="happy.png";
$img2="126.jpg";
$strhh = GetImageSize("$img2");
$strw = GetImageSize("$img1");
$strh = GetImageSize("$img1");
$titleWidth = $strw[0];
$titleHeight = $strh[1];
$strhh = $strhh[1]-$titleHeight-5;
$newImg = ImageCreateFromjpeg("$img2");
$origImg = ImageCreateFrompng("$img1");
ImageCopyResized($newImg,$origImg,5,$strhh,0,0,$titleWidth,$titleHeight,ImageSX($origImg),ImageSY($origImg));
Imagejpeg($newImg);
ImageDestroy($newImg);
?>
搞定了。 代码拿出来大家分享一下。
