[Scilab-users] Fwd: Re: scilab and tif-files

Houps,

I mailed Philipp directly, so here is a copy of my answer and available 
script to read a subset of TIFF.
It might be useful for some of you...

Hello Philipp,

I played a bit with tiff format a while ago (as none of the image 
processing toolboxes could be installed on my work computers).
The long story short: one of our microscope is storing data in a format 
(*.ols) that is just tiff file with some metadata.
I hacked a bit of the tiff specification to only support the subset of 
tiff used by this microscope.
So it might not be exactly what you need, it depends on the tiff files 
you are using.
But maybe it can help you design your own homemade solution.

Cheers,

Antoine
