我想在 php 中将一张图像添加到另一张图像的底部
我有这个来加载图像:
//load top
$top = @imagecreatefrompng($templateTop);
//load bottom
$bottom = @imagecreatefrompng($templateBottom);
现在我想将它们添加到一张图片中并一起显示顶部和底部。
我可以用什么方法来做到这一点?
Thanks!
Use 图像复制:
$top_file = 'image1.png';
$bottom_file = 'image2.png';
$top = imagecreatefrompng($top_file);
$bottom = imagecreatefrompng($bottom_file);
// get current width/height
list($top_width, $top_height) = getimagesize($top_file);
list($bottom_width, $bottom_height) = getimagesize($bottom_file);
// compute new width/height
$new_width = ($top_width > $bottom_width) ? $top_width : $bottom_width;
$new_height = $top_height + $bottom_height;
// create new image and merge
$new = imagecreate($new_width, $new_height);
imagecopy($new, $top, 0, 0, 0, 0, $top_width, $top_height);
imagecopy($new, $bottom, 0, $top_height+1, 0, 0, $bottom_width, $bottom_height);
// save to file
imagepng($new, 'merged_image.png');
