我有透明的图像,我想覆盖整个图像,以赋予它更大的效果.在此代码中,它会裁剪现有图像.它合并了两个,但最后的顶部没有显示alpha.我怎样才能解决这个问题？
<?
$dst_x = 0; // X-coordinate of destination point.
$dst_y = 0; // Y --coordinate of destination point.
$src_x = 163; // Crop Start X position in original image
$src_y = 0; // Crop Srart Y position in original image
$dst_w = 469; // Thumb width
$dst_h = 296; // Thumb height
$src_w = 469; // $src_x + $dst_w Crop end X position in original image
$src_h = 296; // $src_y + $dst_h Crop end Y position in original image
// Creating an image with true colors having thumb dimensions.( to merge with the original image )
$dst_image = imagecreatetruecolor($dst_w,$dst_h);
// Get original image
$src_image = imagecreatefromjpeg("http://www.ucatholic.com/wp-content/uploads/2012/10/Sallixtus-631x295.jpg");
// Cropping
imagecopyresampled($dst_image,$src_image,$dst_x,$dst_y,$src_x,$src_y,$dst_w,$dst_h,$src_w,$src_h);
// Saving
imagejpeg($dst_image,"images/crop.jpg");
$src = imagecreatefrompng('http://www.EdVizenor.com/images/saintCover.png');
/// THIS LINE NOT WORKING - - // Copy and merge
imagecopymerge($dst_image,$src,469,296,100);
header('Content-Type: image/png');
imagegif($dst_image);
?>
不要使用imagecopymerge,使用imagecopy,然后它将正常工作,你的水印将显示alpha.
imagecopy($dst_image,296);
