- TIFF magic number changes from "42" to "84" (double 42 ??)
I'd prefer 66 (= 0x42) or 258 (a base 64 noted number 42) to keep the meaning behind it
A tag is now made up of 16 bytes, the last field is 8 bytes long, and either contains the data (if it will fit in 8 bytes), or an 8 byte pointer to the location of the data.
If we do changes, our goal should be not to change it again two years later. So maybe the following changes should also be done:
- the Count field of an entry should also be 8 bytes. No one will use tiles or strips with more than 4 GB data today, but who knows about tomorrow?
- the Tag field may be expanded to be 4 bytes to have plenty of tags left for future enhancements.
