- 水印图的完善版,可以完美生成透明水印 /** * 操作图片(图片水印) * string $image_Mark 水印地址 * int $x x轴位置 * int $y y轴位置 * int $pct 合并程度 100为完全合并,无透明 */ public function imageMark ($image_Mark,$x=0,$y=0,$pct=100) { $info2=getimagesize($image_Mark); $width=$info2[0];//水印宽 $height=$info2[1];//水印高 $type=image_type_to_extension($info2[2],false); $fun="imagecreatefrom{$type}"; $water=$fun($image_Mark);//创建水印图 if($pct==100){ imagecopy($this->image,$water,$x,$y,0,0,$width,$height);//无透明 }else{ //1.生成真彩图 $img = imagecreatetruecolor($width,$height); //2.把原图画入画板 imagecopy($img,$this->image,0,0,$x,$y, $x+$width, $y+$height); //3.在画板中加入水印 imagecopy($img,$water,0,0,0,0,$width,$height); //4.把画板中的画改变透明度后画入原图,使得水印有了透明效果 imagecopymerge($this->image,$img,$x,$y,0,0, $width, $height,$pct); imagedestroy($img); } imagedestroy($water);//释放水印图内存 }
