為什么80%的碼農都做不了架構師？>>> ??

廢話不多說，直接上代碼，一貫作風不寫注釋?

createImages ? 用來創建一個真彩色底層
setColor ? ? ? 設置顏色(RGB)
setAlphaColor ?設置透明度
setTXT ? ? ? ? 設置圖片中文字
setCenterTXT ? 同上，只是會自動居中
copyIMG ? ? ? ?獲取某張圖片用來做背景
fillBG ? ? ? ? 填充顏色
echoIMG ? ? ? ?輸出圖片

具體參數看代碼就知道；

$img = new WaterMark(225,170);

$img->copyIMG('./temp/bg.png');

$img->setCenterTXT($name,30,$img->setColor(0,0,0),'STXIHEI.TTF');

$img->echoIMG('./images/ImgfileName','','png');
