根據(jù)企業(yè)真實需求背景，java實現(xiàn)jpg、png、tif、gif 任意圖像格式轉換

方法名說明

imageConvertCommon	任意圖像轉換通用類
imageConvertToGIF	圖像任意格式轉gif
imageConvertToTif	圖像任意格式轉tif
imageConvertToJPG	圖像任意格式轉jpg
imageConvertToPNG	圖像任意格式轉png

說一下特殊處理的部分，就是動態(tài)傳后綴名，這個地方重命名用的是帶.的，但是，在格式轉換這一行是不帶.的，這里要注意，可以采用替換或者截取的方式，這里才去的是替換，都一樣吧！
