问题描述
我想给图像加水印并保存.这是我正在使用的代码.在这里,它正在输出图像并将该输出存储到文件中.我想保存而不输出.
I want to watermark an image and save it. here is the code i am using for it. Here it is outputting the image and is storing that output to the file. I want to save it without outputting it.
// Load the stamp and the photo to apply the watermark to
$stamp = imagecreatefrompng('stamp.png');
$im = imagecreatefromjpeg('proverbs.jpeg');
// Set the margins for the stamp and get the height/width of the stamp image
$marge_right = 10;
$marge_bottom = 10;
$sx = imagesx($stamp);
$sy = imagesy($stamp);
// Copy the stamp image onto our photo using the margin offsets and the photo
// width to calculate positioning of the stamp.
imagecopy($im, $stamp, imagesx($im) - $sx - $marge_right, imagesy($im) - $sy - $marge_bottom, 0, 0, imagesx($stamp), imagesy($stamp));
// Output and free memory
header('Content-type: image/png');
ob_start();
// output jpeg (or any other chosen) format & quality
imagejpeg($im, NULL, 85);
// capture output to string
$contents = ob_get_contents();
// end capture
ob_end_clean();
//imagepng($im);
imagedestroy($im);
$fh = fopen("proverbs.jpeg", "w" );
fwrite( $fh, $contents );
fclose( $fh );
推荐答案
将其保存到文件中吗?
只需更改
imagejpeg($im, NULL, 85);
到
imagejpeg($im, 'image.jpg', 85);
