I'm new to C# , I use MS visual studio.NET 2003.
I have some TIFF images, I want to write a program using c# that reads an
image (.tiff) and prints all its tags. can anyone guid me to the right way?
Thanks

I've done this. It would require getting your hands on the Adobe Tiff file
byte order documentation. It's a big job, as TIFF files are quite
extensible. They can hold multiple images, store all sorts of meta data
about the images, and even store them in big-endian or little-endian byte
order. I believe there are some libraries around that can parse TIFFs as
well. I couldn't tell you how good any of them are.

Thanks for your replies
is there any free library to read the tags?
Thanks

Yes. Google for them.

First you need the TIFFspec...

http://partners.adobe.com/public/developer/tiff/index.html

Then you open your image as a bitmap
Get the propertyitems and you can go from there...

System.Drawing.Bitmap newbit = new
System.Drawing.Bitmap("c:\\temp\\test.tif");

System.Drawing.Imaging.PropertyItem[] newprop;

newprop=newbit.PropertyItems;

Property Items seem to have a structure of...
Id - number value to match the tag id in the spec....
Len
Type
Value

and this matches what you can find in the spec....
