GD 函数合成图片问题(一张jpg,一张png)
RT:
请问用php怎么能合成两张图片呢?
一张是png 透明的底图,另一张是jpg 图片

现在想让jpg的图片合成到png的底图上面,成为一张新的图片,如何实现呢?

另外问下,是不是合成的图片要尺寸一样大呢?还是底图可以大点的?

本人在网上也找了一些方法,但好像都不行

  $path_1 = "topic_assets/522592b5d61cb_ip4.jpg";<br />  $path_2 = "topic_assets/topic_border_android.png";<br />	//echo $path_1;<br />	$image=imagecreatefromjpeg($path_1);  <br />	$wm=imagecreatefrompng($path_2);   <br />	$im=imagecreatetruecolor(imagesx($image),imagesy($image));   <br />	imagecopy($im,$image,0,0,0,0,imagesx($image),imagesy($image));   <br />	imagecopy($im,$wm,0,0,0,0,imagesx($wm),imagesy($wm));
Copy after login


做过类似的,给个解决方案吧...
