PHP添加中文水印

示例代码１：

<?php
Header("Content-type: image/png");      /*通知浏览器,要输出图像*/
$im       = imagecreate(400 , 300);        /*定义图像的大小*/
$gray     = ImageColorAllocate($im , 235 , 235 , 235);
$pink     = ImageColorAllocate($im, 255 , 128 , 255);

$fontfile = "simkai.ttf";

/* $fontfile 字体的路径,视操作系统而定,可以是 simhei.ttf(黑体) , SIMKAI.TTF(楷体) , SIMFANG.TTF(仿宋) ,SIMSUN.TTC(宋体&新宋体) 等 GD 支持的中文字体*/
$str   = iconv('GB2312','UTF-8','中文水印');     /*将 gb2312 的字符集转换成 UTF-8 的字符*/
ImageTTFText($im, 30, 0, 100, 200, $pink , $fontfile , $str);
/* 加入中文水印 */
Imagepng($im);
ImageDestroy($im);
?>

 

 

示例代码２：

<?
header("Content-type: image/jpeg");
$image = "1.jpg"; //原图
$fnt = "c:/windows/fonts/stcaiyun.ttf"; // 彩云
$str = "谨防盗版 谨防盗版";
//$str = iconv("GB2312","UTF-8",$str);
$size = 40;
$angle = 20;
$ar = imagettfbbox($size, $angle, $fnt, $str);
$width = $ar[2];
$height = max($size,$ar[1]-$ar[5]);
$im = imagecreatefromjpeg($image);
//$white = imagecolorallocate($im, 255,255,255);
$color = imagecolorallocatealpha($im, 255,255,255,1);
for($i=0;$i<5;$i++) {
//$color = imagecolorclosestalpha($im,255,255,255,90-$i*10);
imagettftext($im, $size, $angle, 40-$ar[6], $height-$ar[1]+100*$i, $color, $fnt, $str);
}
imagejpeg($im);
imagedestroy($im);
?>
