When you speak of Type III and Type IV compression, what categorization are you speaking of. Has some organization established standards, like ISO? What we have is numerous catalogs. most pages are simply text, many are non-English Sometimes a photograph occures, but but that is infrequent in comparizson to the overall document.What I am considering is Huffman encoding the entire document, and havingg an association pointer with positioning ing info connecting a PICT or TIFF file to pages in which pictures occur. This strategy could produce much more efficient file sizes. It just doesn't seem appropriate to encode the entire page as a picture when most of it is text.
