sub*_*ero 20 php merge png resize image
情况是这样的:我有一个50x50的小图片.我还有一个小的50x50透明图片,其中包含一个50x50 pic的帧,所以我基本上想把透明的png 放在图像的顶部并合并这两个,这将导致最终的第三张图片看起来像这样:http ://img245.imageshack.us/i/50x50n.png
注意:我不想仅使用HTML(我通过编写一个将透明png放在原始图像顶部的javascript插件来实现这一点).
谢谢.

您可以使用PHP GD2库将两个图像合并在一起.
例:
<?php
# If you don't know the type of image you are using as your originals.
$image = imagecreatefromstring(file_get_contents($your_original_image));
$frame = imagecreatefromstring(file_get_contents($your_frame_image));
# If you know your originals are of type PNG.
$image = imagecreatefrompng($your_original_image);
$frame = imagecreatefrompng($your_frame_image);
imagecopymerge($image, $frame, 0, 0, 0, 0, 50, 50, 100);
# Save the image to a file
imagepng($image, '/path/to/save/image.png');
# Output straight to the browser.
imagepng($image);
?>
