extract data point from tiff picture

I did some google seraches but coul开发者_开发技巧d not find an answer. Is it possible to extract data points from a tiff image? If it is a vector type format it should be possible I reckon ... I am a fairly good programmer (C# preferably). Thanks.

Its not clearly for me what is "data" in your case. But hope TIFF File format specification will help http://partners.adobe.com/public/developer/en/tiff/TIFF6.pdf

Matlab and some code called grabit seem to help. Not sure whether there are better ways but that helped so far:

File Exchange

The data points are red. Maybe that also clarifies what I mean by data.
