Keshab,

> What are the possible tiff image formats available/theoretically possible 
> ?

TIFF is a format where different properties multiply, i.e. the overall model 
is that everything freely combines with everything (except for some logical 
limitations, like you can't have JPEG compression combined with 1 bits per 
sample data simply because that particular compression mode doesn't define 
this). In other words, there are different steps you have to think of, but 
you need to think of them one by one and they need to work without depenency 
or any direct coupling to particulars of other steps. In other words, you 
have to stop thinking about TIFF as a fixed limited sets of possibilities, 
as that's the way you end up with a impossible to accomodate number of 
options. Rather, you need to think of each separate property as having a 
fixed limited set of possibilities, and then make your code freely combine 
these. Think 'multiplication' of options, not 'addition'.


Best regards,

Joris
