破壞Huffman Tree的JPEG...part 3

jpegfixed.bat 轉換成 破壞的Huffman Tree
jpegoptimize.bat 轉換成 優化的Huffman Tree
jpegprogressive.bat 轉換成 漸進的Huffman Tree

修正檔名有空白字會出現問題...
修正共用同一組DC/AC的Huffman Table (18:40)

Optimize 1082948bytes
Progressive 1030805bytes
Fixed + rar(ppmd) 1014803bytes
Fixed + bbb 979258bytes

Fixed原理就是讓JPEG編碼會呈現8bits或16bits甚至24bits這種bytes型態
以方便其他壓縮可以更容易壓縮
雖然比不上PackJPG和Paq8o8以及商業產品Stuffit 11...
