public function entryOp() {

$img = 'http://newmall.yewugou.com/ylfapporderform/images/test.png';

list($width, $height) = @getimagesize($img);

$image = imagecreatefrompng($img);//建立圖檔模闆

imagesavealpha($image,true);//保留通道資訊

$thumb = imagecreatetruecolor($width,$height);//建立真彩圖

//設定字型開始

$black = imagecolorallocate($image, 98, 52, 11);//拾色器

$font_file = $_SERVER['DOCUMENT_ROOT'].DIRECTORY_SEPARATOR.'mobile'.DIRECTORY_SEPARATOR.'fonts'.DIRECTORY_SEPARATOR.'msyh.ttf';

imagefttext($image, 25, 0, 980, 125, $black, $font_file, '2016年11月05日');

imagefttext($image, 25, 0, 980, 165, $black, $font_file, '2017年05月05日');

imagefttext($image, 25, 0, 630, 295, $black, $font_file, '夢兒');

imagefttext($image, 25, 0, 630, 570, $black, $font_file, '伐木累');

$color = imagecolorallocate($image, 255, 84, 31);

imagefttext($image, 40, 0, 530, 690, $color, $font_file, '動作');

imagealphablending($thumb,false);

imagesavealpha($thumb,true);

imagecopyresampled($thumb,$image,0,0,0,0,$width,$height,$width,$height);
