If a document is marked with line-shift coding, it is particularly nasty to subscribe to the encoding if the document is in paper format. (Kessler, 2001)- Word-Shift Coding: In word shifting coding, code words are coded into a document by shifting the horizontal locations of words within text lines, while maintaining a natural spacing appearance. development the Alternate Methods: 1- Syntactic methods; 2- Semantic methods2- In images:To deal data in imag es, understanding palette... !
